whole world. The world production of fish is around 100 million tons/year and 70% of them is destined exclusively to the human feeding. The fish and derived have a great importance in the human diet, contributing with ¼ of offer of protein of animal origin. Sseafood and fish are health, because they are rich in proteins, vitamins, micronutrients and insatured fats. However, one of the most important themes, in public health, refers to the safe food. Only in the USA, 76 million case of foodborne diseases occurs every year, with 325 thousand hospitalized and 5 thousand deaths. According to the microbiological parameters, the Brazilian Food Sanitation Standard (Decree No. 12, 2001) defined that fish, roes of fish, crustaceans and mollusks in natura cooled or frozen, no consumed raw should present up to 103 MPN of coagulase positive Staphylococcus in the absence of Salmonella in 25g. Based on this, this work verified the microbiological quality of fish and seafood retailed in supermarkets and fish store in Botucatu city. A hundred samples were analyzed, being 65 frozen (65%) and 35 cooled (35%). The samples included various kinds of fish and seafood. Among the frozen samples, 31 were fish and 34 seafood. About the cooled ones, 28 were fish and 7 seafood. The methods used for analysis are in agreement with APHA (2001). The samples were acquired in 4 establishments (3 supermarkets and a fish store). Ina total of 100 samples, all were negative to coagulase positive Staphylococcus and 2 were positive for Salmonella (2%). According to the results, we conclude that the presence of Salmonella is a risk factor for the consumers' health and these foods should not be consumed raw. In spite of the freezing to be a good conservation way, this process doesn't totally eliminate the pathogens of the food

This paper is aimed to analyze the distribution of green areas in public spaces of the Limeira city. This study seeks to diagnose the current situation of the distribution of green areas in the city of Limeira and how these areas contribute to the quality of life of city residents. The concept of public green areas can be defined in different ways , and for this study were considered spaces where there is a prevalence of vegetation, parks , public gardens , squares and medians of avenues performing aesthetic and ecological , whose soil is not completely covered . The presence of urban green areas has several functions, such as a space for recreation , environmental education and interpretation , and thus contribute to a greater closeness between man and nature . The aim of this study is to discuss what benefits, incentives and difficulties exist for the maintenance and expansion of green areas in the city and investigate the population's perception of, and their relationship with, these spaces

O pescado e seus derivados têm uma grande importância na dieta, em todo o mundo. Sabe-se que peixes e frutos do mar fortalecem o sistema imunológico, contribuem para a redução dos níveis de colesterol, diminuem as chances de depressão, ajudam na formação dos músculos e protegem contra doenças cardiovasculares. Também, são ricos em vitaminas lipossolúveis A, D e E, além do ômega 3. Muitas vezes, esses produtos são consumidos crus ou com pouco preparo e com isso faz-se necessário medidas higiênico- sanitárias, pois podem ser contaminados com micro-organismos causadores de doenças. A análise microbiológica dos alimentos para se verificar a presença de micro-organismos prejudiciais é fundamental para se conhecer as condições de higiene nas quais estes alimentos foram preparados. Assim, 80 amostras de peixes e frutos do mar de peixarias e supermercados de Botucatu, SP, foram analisadas com o objetivo de verificar se esses alimentos estão dentro dos padrões estabelecidos pela legislação brasileira, através da RDC nº12, através da detecção da presença de Salmonella sp., Staphylococcus aureus e determinação do número mais provável de coliformes termotolerantes (CT), mesmo que este último não faça parte dos parâmetros para esse alimento, mas foi pesquisado para avaliação de suas condições higiênicas. Cada amostra (25 gramas) foi homogeneizada em 225ml de água peptonada e para a detecção de S. aureus, utilizou-se método spread Baird Parker, seguida de catalase, coagulase e kit Dry Spot. Para a detecção de Salmonella, utilizou-se caldo tetrationato (35ºC/24h) e Rapapport (42ºC/24h), semeados em ágar SS e XLD. As colônias foram testadas em TSI, ágar fenilalanina e testadas em poli soros somático e flagelar. Quanto aos CT, empregou-se a técnica de tubos múltiplos, inoculando diluições da amostra em caldo Lauril sulfato, na fase presuntiva e depois em caldo EC (45ºC) na fase confirmatória. De ...

Species of colonial green algae from 10 Conservation Units from the Southern Brazil were surveyed. The samplings were carried out in 105 stream reaches, consisting of 10 m length transects. In addition to biological data, some environmental variables were measured: depth, current velocity, water temperature, turbidity, specific conductance, pH, dissolved oxygen and nutrients (total nitrogen and orthophosphate). Three species of colonial green algae [Bohlin Ecballocystis pulvinata var. pulvinata, Tetraspora gelatinosa (Vaucher) Desvaux and T. lubrica (Roth) C Agard] were recorded and these species were described and illustrated. Based on the environmental data, it was observed some patterns of ecological distribution, including the occurrence of E. pulvinata var. pulvinata in environments with higher water temperature and current velocity values, while Tetraspora species typically occurred in environments with lower total nitrogen, orthophosphate and specific conductance values.

Phenolic compounds and antioxidant capacity are defense mechanisms of plants against the oxidative stress damage. Phenolic compounds are synthesized through the phenylpropanoid pathway, where the enzyme phenylalanine-ammonia-lyase plays a key role and it is influenced by light and photoreceptors such as phytochromes. The present research aims to evaluate the phenolic compounds content and antioxidant capacity of the wild Micro-Tom (MT) cultivar tomato fruits and its photomorphogenic mutant tomato plants high pigment 1 (hp1), super responsive to events mediated by light, and aurea (au), quantitative phytochrome deficient. Twenty mature fruits of each genotype (MT, hp1, au) were used in triplicate for analyses. To quantify the total phenolic compounds the Folin-Ciocalteu method was used and the antioxidant capacity was analyzed by Ferric Reducing Antioxidant Power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods. The hp1 mutant presented the highest total phenolic compounds content and higher antioxidant capacity than wild cultivar (MT) and au mutant, which did not differ significantly from MT cultivar.
