Survey on Chlamydophila psittaci in captive ramphastids in São Paulo State, Brazil

Chlamydophila psittaci (C. psittaci) has been detected in 460 avian species, among them the most frequent are the Psittaciformes, Columbiformes, Anseriformes and raptors. In Brazil, the main avian species recognized as healthy carriers belong to the order Psittaciformes and Columbiformes, but very few studies have been done in other bird families. Reports of the occurrence of this disease in the clinical form are rare in the Ramphastids; consequently, they are not commonly evaluated for this agent. The present study reports the investigation of C. psittaci in 25 captive ramphastids from a zoological park in São Paulo State, Brazil. Swabs samples from the cloaca were submitted to semi-nested polymerase chain reaction (semi-nested PCR) for direct detection of the microorganism. Additionally, blood samples obtained from these birds were submitted to the Complement Fixation Test (CFT) for detection of antibodies anti-C. psittaci. The presence of C. psittaci was not detected in the cloacal swab samples tested by the PCR. Nevertheless, 16% (4/25) of the bird's sera were positive by the CFT. Among the species with positive results, there are the saffron toucanet (Pteroglossus bailloni) and black-necked-aracari (Pteroglossus aracari), two species with no descriptions of the survey of C. psittaci published in the literature. Intermittent elimination of C. psittaci is a feature of chronically infected birds; however the absence of a positive-antigen sample did not guarantee that the bird is Chlamydophila-free. The serological results obtained show that the ramphastids tested were previously exposed to the pathogen and developed immune response, but showed no clinical signs of the disease and didn't eliminate regularly the organism in their feces in the moment of the sample collection.

Predição do Consumo Voluntário do Capim-Tanzânia (Panicum maximum, J. cv. tanzânia), sob Pastejo, por Vacas em Lactação, a partir das Características de Degradação

O consumo de matéria seca (CMS) do capim tanzânia de 24 vacas lactantes mestiças (HPB x Gir) e Gir, sob pastejo, foi estimado no mês de janeiro de 1998, a partir da relação entre a digestibilidade da MS da forragem e a produção fecal obtida com auxílio do cromo mordente por meio de um modelo não-linear. Os resultados do consumo estimado foram comparados aos consumos preditos por diferentes equações baseadas nos dados de degradabilidade do capim, no rúmen. A pastagem foi manejada com taxa de lotação de dois animais/ha, em sistema de pastejo rotativo com três dias de ocupação do piquete e 39 dias de descanso. Foram utilizadas para predizer o CMS diferentes equações: CMS = -1,19 + 0,035 (a+ b) + 28,5c (1), CMS = -0,822 + 0,0748 (a+ b) + 40,7c (2), CMS = -8,286 + 0,266a + 0,102b +17,696c (3) e CMS = [%FDN na MS]* [consumo de FDN ] / [(1-a-b)/K P +b/(c+ k p)]/24] (4). As equações, em geral, subestimaram o consumo obtido no modelo não-linear (9,6 kg/vaca/dia). Os consumos médios de capim de 6,2 e 6,0 kg MS/vaca/dia obtidas, respectivamente, nas equações de (2) e (4) foram semelhantes entre si e inferiores ao das equações de (1) (12,7 kg/vaca/dia) e (3) (8,1 kg/vaca/dia). A predição do consumo de forrageiras tropicais, sob pastejo, utilizando-se as equações baseadas nas variáveis da degradação in situ, constitui um importante potencial para estas avaliações. Entretanto, mais estudos dessa natureza devem ser realizados para validar o uso destas equações na prática.

Estimativa da ingestão voluntária a partir das características de degradação do capim-coastcross (Cynodon dactylon L. Pers.), sob pastejo, por vacas em lactação

O consumo de matéria seca (CMS) do capim-coastcross, sob pastejo, de vacas lactantes mestiças (HPB x Gir) e Gir, foi calculado a partir da relação entre a digestibilidade in vitro da MS (DIVMS) da forragem (extrusa colhida com animais esôfago- fistulados) e a produção fecal obtida com auxílio do cromo mordante por meio de um modelo não-linear. A pastagem foi manejada com uma taxa de lotação de 1,6 e 3,2 animais/ha, respectivamente para as épocas seca e chuvosa do ano, num sistema de pastejo rotativo com três dias de ocupação e 27 dias de descanso. Quatro diferentes equações baseadas em variáveis de degradação ruminal foram utilizadas para predizer o consumo de MS: CMS = -1,19 + 0,035 (a+ b) + 28,5c (1), CMS = -0,822 + 0,0748 (a+ b) + 40,7c (2), CMS = -8,286 + 0,266a + 0,102b +17,696c (3) e CMS = [%FDN na MS]* [consumo de FDN ] / [(1-a-b)/K P +b/(c+ k p)]/24] (4). Os dados observados utilizando as equações 1 e 2 (12,2 e 12,7 kg/vaca/dia respectivamente) foram similares entre si e superiores aos resultados obtidos na equação 4 (7,8 kg/vaca/dia). Já o resultado obtido pela equação 3 (5,5 kg/vaca/dia) foi menor do que aqueles determinados pelas outras equações, subestimando o CMS calculado a partir do cromo mordante (6,3 kg/vaca/dia). A predição do consumo de forrageiras tropicais sob pastejo, utilizando equações baseadas nas variáveis de degradação, constitui um importante potencial para estas avaliações. Entretanto, mais estudos devem ser realizados antes de se usarem estas equações na prática.

Massa de forragem, composição morfológica e química de capim-tanzânia sob diferentes dias de descanso e altura de resíduo pós-pastejo

The experiment was conducted at UNESP/FCAV, Jaboticabal, SP, with the objective of evaluating the influence of the rest period and height of the residue post-grazing on the dry matter mass, morphologic composition and on the chemical composition of the Tanzania-grass pre-grazing condition, under rotational grazing. The treatments consisted of the combination of two rest periods (25 and 35 days) and two residue height post-grazing (30 and 50 cm), as a complete randomized design in factorial arrangement 2 x 2, with three replications, with the grazing cycles considered as sub plots. The herbage mass of stem, leaves, dead material and the leaf: stem ratio were significantly influenced (P<0.05) by the grazing cycles. The percentage of CP in the leaf and stem and the NDF in the stem, leaf and whole plant were influenced positively (P<0.05) by the grazing cycles. It was observed that the short rest periods associated with the smallest residue height post-grazing presented the best results in terms of herbage mass and chemical characteristics of the herbage.

Possibilidade de aplicação de misturas de herbicidas de ação total com Jato dirigido em mamoneira de porte anão

Com o objetivo de avaliar os efeitos da aplicação em jato dirigido com e sem proteção do bico de pulverização através de chapéu-de-napoleão para misturas de herbicidas de ação total na cultura da mamoneira de porte anão, na safra 2004/2005, um experimento foi conduzido no município de Garça-SP, utilizando-se o híbrido Lyra e espaçamento de 1,0 x 0,5 m. O delineamento experimental utilizado foi o de blocos casualizados, com tratamentos em esquema fatorial 2 x 10, com quatro repetições, em que o primeiro fator representou a forma de aplicação de jato dirigido com e sem uso de chapéu-de-napoleão e o segundo os herbicidas: glyphosate (0,72 kg ha-1); glyphosate + 2,4-D (0,72 + 0,35 kg ha-1); glyphosate + flumioxazin (0,72 + 0,025 kg ha-1); glyphosate + carfentrazone-ethyl (0,72 + 0,016 kg ha-1); glyphosate + diuron (0,72 + 0,75 kg ha-1); MSMA + diuron (1,44+ 0,75 kg ha-1); paraquat + diuron (0,9 kg ha-1); paraquat + diquat (0,20 + 0,20 kg ha-1); paraquat + bentazon (0,40 + 0,48 kg ha-1); e testemunha capinada. A aplicação dos herbicidas foi feita em pós-emergência das plantas daninhas, nas entrelinhas da cultura, utilizando-se pulverizador costal pressurizado com CO2, com uma ponta XR 8002-VS para o uso de chapéu-de-napoleão e duas pontas XR 11002-VS, espaçadas de 50 cm, para condição sem proteção, ambas com consumo de calda equivalente a 200 L ha-1. O herbicida glyphosate e as misturas de paraquat + bentazon, glyphosate + 2,4-D e paraquat + diquat proporcionaram os maiores níveis de produtividade da mamoneira Lyra quando aplicados em jato dirigido e com auxílio de chapéu-de-napoleão. As misturas paraquat + bentazon (0,40 + 0,48 kg ha-1) e paraquat + diquat (0,20 + 0,20 kg ha-1) demonstraram ser as mais indicadas para aplicação em jato dirigido com proteção do bico de pulverização.

Desgaste de polímeros estruturais de engenharia em contato de deslizamento com cilindro metálico

Present work proposed to map and features the wear mechanisms of structural polymers of engineering derived of the sliding contact with a metallic cylindrical spindle submitted to eccentricity due to fluctuations in it is mass and geometric centers. For this it was projected and makes an experimental apparatus from balancing machine where the cylindrical counterbody was supported in two bearings and the polymeric coupon was situated in a holder with freedom of displacement along counterbody. Thus, the experimental tests were standardized using two position of the two bearings (Fixed or Free) and seven different positions along the counterbody, that permit print different conditions to the stiffness from system. Others parameters as applied normal load, sliding velocity and distance were fixed. In this investigation it was used as coupon two structural polymers of wide quotidian use, PTFE (polytetrafluroethylene) and PEEK (poly-ether-ether-ketone) and the AISI 4140 alloy steel as counterbody. Polymeric materials were characterized by thermal analysis (thermogravimetric, differential scanning calorimetry and dynamic-mechanical), hardness and rays-X diffractometry. While the metallic material was submitted at hardness, mechanical resistance tests and metallographic analysis. During the tribological tests were recorded the heating response with thermometers, yonder overall velocity vibration (VGV) and the acceleration using accelerometers. After tests the wear surface of the coupons were analyzed using a Scanning Electronic Microscopy (SEM) to morphological analysis and spectroscopy EDS to microanalysis. Moreover the roughness of the counterbody was characterized before and after the tribological tests. It was observed that the tribological response of the polymers were different in function of their distinct molecular structure. It were identified the predominant wear mechanisms in each polymer. The VGV of the PTFE was smaller than PEEK, in the condition of minimum stiffness, in function of the higher loss coefficient of that polymer. Wear rate of the PTFE was more of a magnitude order higher than PEEK. With the results was possible developed a correlation between the wear rate and parameter (E/ρ)1/2 (Young modulus, E, density, ρ), proportional at longitudinal elastic wave velocity in the material.

Desenvolvimento de uma desfribadeira para obtenção da fibra da folha do abacaxi

In 1998 the first decorticator was developed in the Textile Engineering Laboratory and patented for the purpose of extracting fibres from pineapple leaves, with the financial help from CNPq and BNB. The objective of the present work was to develop an automatic decorticator different from the first one with a semiautomatic system of decortication with automatic feeding of the leaves and collection of the extracted fibres. The system is started through a command system that passes information to two engines, one for starting the beater cylinder and the other for the feeding of the leaves as well as the extraction of the decorticated fibres automatically. This in turn introduces the leaves between a knife and a beater cylinder with twenty blades (the previous one had only 8 blades). These blades are supported by equidistant flanges with a central transmission axis that would help in increasing the number of beatings of the leaves. In the present system the operator has to place the leaves on the rotating endless feeding belt and collect the extracted leaves that are being carried out through another endless belt. The pulp resulted form the extraction is collected in a tray through a collector. The feeding of the leaves as well as the extraction of the fibres is controlled automatically by varying the velocity of the cylinders. The semi-automatic decorticator basically composed of a chassis made out of iron bars (profile L) with 200cm length, 91 cm of height 68 cm of width. The decorticator weighs around 300Kg. It was observed that the increase in the number of blades from 8 to twenty in the beater cylinder reduced the turbulence inside the decorticator, which helped to improve the removal of the fibres without any problems as well as the quality of the fibres. From the studies carried out, from each leaf 2,8 to 4,5% of fibres can be extracted. This gives around 4 to 5 tons of fibres per hectare, which is more than that of cotton production per hectare. This quantity with no doubt could generate jobs to the people not only on the production of the fibres but also on their application in different areas

Comportamento de cultivares de feijoeiro comum à murcha-de-curtobacterium

No presente trabalho foi avaliada a resistência de 40 cultivares de feijoeiro comum (Phaseolus vulgaris) à murcha-de-Curtobacterium, inoculadas separadamente com dois isolados de Curtobacterium flaccumfaciens pv. flaccumfaciens, e o desenvolvimento da parte aérea de cultivares resistentes e suscetíveis a essa doença, inoculadas ou não com um isolado da bactéria. As reações apresentadas pelas cultivares permitiram verificar que 'IAC Carioca Aruã', 'IAC Carioca Akytã' e 'IAC Carioca Pyatã' foram resistentes e que 'A - 768', 'Aeté', 'Aporé', 'Bambuí', 'Bico de Ouro', 'BR IPA 11 - Brígida', 'Carioca MG', 'Carioquinha', 'Catu', 'Corrente', 'Diamante Negro', 'FT Bonito', 'FT Nobre', 'FT-120', 'IAC Carioca', 'IAC Maravilha', 'IAC Una', 'IAPAR 14', 'IAPAR 16', 'IAPAR 31', 'IAPAR 44', 'IPA 6', 'Iraí', 'Jalo Precoce', 'Jamapa', 'Onix', 'Ouro Negro', 'Pérola', 'R - 161', 'RAO 33', 'Rio Tibagi', 'Rosinha G2', 'Roxo 90', 'Rudá', 'Safira', 'Tarumã' e 'Xamego' foram suscetíveis à murcha-de-Curtobacterium. Plantas de feijoeiro das cultivares resistentes (IAC Carioca Aruã, IAC Carioca Akytã e IAC Carioca Pyatã) apresentaram menor redução da matéria seca da parte aérea do que das suscetíveis (IAC Carioca e Pérola), quando inoculadas com C. flaccumfaciens pv. flaccumfaciens.

Influência da corrente de pulso, do tempo de pulso e diâmetro de gota sobre a estabilidade da transferência metálica no processo MIG-P

To obtain a process stability and a quality weld bead it is necessary an adequate parameters set: base current and time, pulse current and pulse time, because these influence the mode of metal transfer and the weld quality in the MIG-P, sometimes requiring special sources with synergistic modes with external control for this stability. This work aims to analyze and compare the effects of pulse parameters and droplet size in arc stability in MIG-P, four packets of pulse parameters were analysed: Ip = 160 A, tp = 5.7 ms; Ip = 300 A and tp = 2 ms, Ip = 350 A, tp = 1.2 ms and Ip = 350 A, tp = 0.8 ms. Each was analyzed with three different drop diameters: drop with the same diameter of the wire electrode; droplet diameter larger drop smaller than the diameter of the wire electrode. For purposes of comparison the same was determined relation between the average current and welding speed was determined generating a constant (Im / Vs = K) for all parameters. Welding in flat plate by simple deposition for the MIG-P with a distance beak contact number (DBCP) constant was perfomed subsequently making up welding in flat plate by simple deposition with an inclination of 10 degrees to vary the DBCP, where by assessment on how the MIG-P behaved in such a situation was possible, in addition to evaluating the MIG-P with adaptive control, in order to maintain a constant arc stability. Also high speed recording synchronized with acquiring current x voltage (oscillogram) was executed for better interpretation of the transfer mechanism and better evaluation in regard to the study of the stability of the process. It is concluded that parameters 3 and 4 exhibited greater versatility; diameters drop equal to or slightly less than the diameter of the wire exhibited better stability due to their higher frequency of detachment, and the detachment of the drop base does not harm the maintenance the height of the arc

Efeito da intensidade do vento, da pressão e de pontas de pulverização na deriva de aplicações de herbicidas em pré-emergência

Objetivou-se com este trabalho avaliar o efeito de pontas de pulverização, pressão e intensidade do vento na deriva gerada em aplicações simuladas de herbicidas aplicados em pré-emergência. Os modelos de pontas de pulverização e as respectivas pressões testadas foram: SF 11002 (207 e 310 kPa), JA-2 (345 e 655 kPa) e AVI 11002 (207 e 414 kPa). As aplicações foram realizadas em dois períodos, em dias com condições de velocidade de vento distintas, em uma área de 1.200 m², localizada na Fazenda Experimental da FCA/UNESP. Um pulverizador com barra de 12 m, 24 bicos e tanque de 600 L foi utilizado nas aplicações. A calda de aplicação foi composta por água e o corante alimentício FDC-1 foi usado como traçador. A deriva foi amostrada por coletores ativos fixados sobre a barra de pulverização. As velocidades mínimas, médias e máximas de vento registradas no primeiro e segundo períodos das aplicações foram de 7, 14 e 23 km h-1 e 1, 5 e 18 km h-1, respectivamente. Nas duas ocasiões de aplicação, as pontas de pulverização com indução de ar AVI 11002 e de jato cônico vazio JA-2 a 655 kPa resultaram nas menores e maiores quantidades de depósito de líquido detectadas, respectivamente. A maior intensidade do vento incrementou a deriva. A redução na pressão pode ser utilizada para controle de deriva, mas a seleção adequada de uma ponta mostrou ser mais eficiente para esse propósito.

Estudo do Cultivo de dois clones de Escherichia coli recombinantes (eIF, LACK) para a Expressão de Antígenos da Leishmania chagasi

With advent of the technology of the recombinant DNA, the recombinant protein expression becomes an important tool in the studies of the structure, function and identification of new proteins, mainly with therapeutical purposes. The Escherichia coli has been procarioto predominant in the studies of genetic engineering due to wealth of information regarding its metabolism. Despite the expressivo advance of the studies of molecular biology and the immunology of the infections, it does not exist, currently, no prophylactic drug capable to prevent calazar. Of this form, it exists a great necessity of specific antigen identification for the vaccine development and kits for disgnostic against the visceral Leishmaniose. In this context, this work objectified to study the recombinant antigen expression of the Leishmania chagasi during the culture of Escherichia coli in shaker. A first set of assays was carried through with the objective of if knowing the kinetic behavior of the growth of two clones recombinant proteins (eIF, LACK) in two different compositions of culture medium (2xTY, TB) supplemented by antibiotics, without IPTG addition. In the second stage of the assays, the procedure of induction for IPTG was carried through, in order to verify the influence of the composition of the ways tested in the expression them recombinant proteins. On the basis of the gotten results, can be observed that the high complexity of culture medium favored the kinetic one of growth of clones recombinant (eIF, LACK), however, to if to deal with the assays submitted to the procedure of induction for IPTG, the raised complexity of culture medium did not favor the expression of recombinant proteins. On the other hand, they had been gotten resulted positive for all clones recombinant (eIF, LACK) tested, confirmed through the eletroforético profile

Deposição e distribuição de calda de pulverização em plantas de feijoeiro (Phaseolus vulgaris) e capim-braquiária (Brachiaria decumbens)

Com o objetivo de avaliar a deposição e distribuição de solução traçante em plantas de feijoeiro e capim-braquiária, foi conduzido experimento no NuPAM-FCA/ UNESP, campus de Botucatu-SP, utilizando um simulador de pulverização em ambiente controlado. Os tratamentos utilizados foram: bico jato plano XR Teejet (XR110.02VS) + surfactante Aterbane BR (0,5% v/v); bico jato cônico Conejet (TXVK-4) + surfactante Aterbane BR (0,5% v/v); bico jato plano XR Teejet (XR110.02VS); e bico jato cônico Conejet (TXVK-4). em todos os tratamentos foi aplicada uma solução de NaCl (0,5% p/v) + corante Poliglow laranja (0,5% p/v) + mancozeb (0,5% p/v). As unidades experimentais constituíram-se de vasos com duas plantas-alvo de capim-braquiária posicionadas sob uma planta-alvo de feijoeiro. A visualização da distribuição das gotas nas folhas de capim-braquiária foi efetuada com auxílio de luz negra, e o depósito da calda na superfície das plantas foi quantificado através da condutividade elétrica da solução aplicada e coletada por meio de lavagem de ambos os alvos. Os bicos de pulverização, jato plano (XR Teejet) e cônico (Conejet), não apresentaram diferença no depósito nos folíolos totais de feijoeiro quando submetidos a mesma condição de calda de pulverização. No entanto, o bico jato plano XR Teejet (XR110.02VS) e o bico jato cônico Conejet (TXVK-4) proporcionaram aumento de 67,1 e 61,5% na deposição da calda em relação a área foliar e 106,4 e 66,9% para matéria seca, respectivamente, em relação ao bico jato plano XR Teejet (XR110.02VS) + surfactante Aterbane BR (0,5% v/v) e ao bico jato cônico Conejet (TXVK-4) + surfactante Aterbane BR (0,5% v/v). Para o capim-braquiária, o bico cônico Conejet proporcionou deposição superior e distribuição mais uniforme em relação ao jato plano XR Teejet.

Variáveis qualitativas da pulverização em feijão, Bidens pilosa E Brachiaria plantaginea

Conduziu-se este trabalho, com o objetivo de avaliar a qualidade da deposição da calda de pulverização em plantas de feijão (Phaseolus vulgaris L.), Bidens pilosa L. e de Brachiaria plantaginea (Link) Hitchc. presentes na linha e entrelinha da cultura. Foi utilizado como traçador o corante Azul Brilhante FDC-1 (500 ppm). Utilizaram-se cinco pontas de pulverização: jato plano (XR 110015 VS e XR 11002 VS), jato plano duplo (TJ60 11002 VS) e jato cônico (TX-6 VS e TX-8 VS) e dois volumes de aplicação 150 e 200 L ha-1. O delineamento utilizado foi de blocos ao acaso, com 4 repetições. Foram amostradas 25 plantas em cada parcela/repetição, de plantas de feijão e plantas daninhas presentes na linha e na entrelinha da cultura. Após a aplicação, as plantas foram coletadas e lavadas em água destilada para quantificação do traçador em espectrofotômetro. Os dados ajustaram-se à curva de regressão pelo modelo de Gompertz. Os resultados evidenciaram que: para as plantas de feijão as pontas XR 110015 e TJ60 proporcionaram as deposições mais uniformes, nos volumes de 150 e 200 L ha-1, respectivamente; a ponta TX-6 no volume de 150 L ha-1 apresentou melhor uniformidade de distribuição para ambas as espécies de plantas daninhas presentes na linha da cultura; para as plantas daninhas presentes na entrelinha, no volume de 150 L ha-1, destacaram-se as pontas XR 110015 e TJ60 11002 para B. pilosa e B. plantaginea, respectivamente, no volume de 200 L ha-1 destacou-se a ponta TX-8 para ambas as espécies.

Avaliação de dois clones de Escherichia coli recombinante quanto ao crescimento e expressão de antígenos de Leishmania chagasi (kmp11 e P36)

Visceral leishmaniosis caused by Leishmania chagasi, also known as calazar, presented, in the period from 1990 to 2005, tax of incidence in Brazil varying between 1 and 3 cases for 100 000 inhabitants. The Northeast region that up to the year of 2000 contributed with almost 90% of the registered cases is reducing his participation in the current decade, reaching 56% in 2005. Conventional leishmaniasis treatment is costly and it shows high toxicity, demanding more research for alternative treatments, with special interest in development of vaccines and diagnosis kits which include production of recombinant antigens by host cells. Escherichia coli has been the microorganism most studied and used as a host for recombinant protein production. Therefore, the aim of this work was to study the influence of induction on cellular growth and to verify the type of Leishmania chagasi antigens expression (intra or extracellular) during two recombinant E. coli clones (kmp11 and P36) cultivation in rotary incubator (shaker) using three different media (2xTY, TB, FASS+EL). For that, tests were carried out using conditions established in the literature for E. coli (37°C and 200 rpm) and media supplemented with antibiotics to guarantee that only competent cells grows. First, tests were carried out without induction in order to verify the two microorganisms kinetic behavior (growth and substrate consumption) in different media. Next, the induction was carried out through the addition of IPTG (1mM as final concentration), at the first hour of cultivation. It was observed that protein expression were intracellular for all clones and media tested, however the highest level of expression was clearly observed by the electrophoresis band density (intensity) for 2xTY medium and kmp11 protein. Although it contains the lowest substrate concentration, consequently, a reduced cellular concentration when compared to other media, it appeared that this medium and clone combination is the most indicated for recombinant protein production. Therefore, the objective of this work was achieved, since the interested proteins were produced. Consequently, this result motivates new studies for production optimization using different cultivation strategies

Hidrólise de resíduos lignocelulósicos utilizando extrato enzimático celulolítico produzido por Trichoderma reesei atcc 2768

Cellulolytic enzymatic broth by Trichoderma reesei ATCC 2768 cultived in shaker using cashew apple bagasse and coconut shell bagasse, as substrate for fermentation, was used to investigate the enzymatic hydrolysis of these substrates after pre-treatment with 1 M NaOH, wet-oxidation as well as a combination of these treatments. Hydrolysis runs were carried at 125 rpm, 50ºC and initial pH of 4.8 for 108 hours. Enzymatic broth produced using cashew apple bagasse treated with 1M NaOH (1.337 UI/mL CMCase and 0.074 UI/mL FPase), showed after the hydrolysis an initial of 0.094 g of reducing sugar/g of substrate.h with 96% yield of total reducing sugars while for the coconut shell bagasse treated using the alkaline process (0.640 UI/mL CMCase and 0.070 UI/mL FPase) exhibited an initial hydrolysis velocity of 0.025 g of reducing sugar/g of substrate.h with 48% yield of total reducing sugars. For the treatment with wet-oxidation using cashew apple bagasse as substrate enzymatic broth (0.547 UI/mL CMCase) exhibited an initial hydrolysis velocity of 0.014 g of reducing sugars/g of substrate.h with a lower yield about 89% of total reducing sugars compared to the alkaline treatment. Enzymatic broth produced using coconut shell treated by wet-oxidation showed an initial hydrolysis velocity of 0.029 g of reducing sugar/g of substrate.h with 91% yield. However, when the combination of these two treatments were used it was obtained an enzymatic broth of 1.154 UI/mL CMCase and 0.107 FPase for the cashew apple bagasse as well as 0.538 UI/mL CMCase and 0,013 UI/mL de FPase for the coconut shell bagasse. After hydrolysis, initial velocity was 0.029 g of reducing sugar/g of substrate.h. with 94% yield for the cashew apple bagasse and 0.018 g de reducing sugar/g of substrate.h with 69% yield for coconut shell bagasse. Preliminary treatment improves residues digestibility showing good yields after hydrolysis. In this case, cellulose from the residue can be converted into glucose by cellulolytic enzymes that can be used for ethanol production
