The effect of sodium chloride on the formation of W/O microemulsions in soy bean oil/surfactant/water systems and the solubilization of small hydrophilic molecules

Partial pseudoternary phase diagrams were constructed for soy bean oil (SBO)/surfactant/NaCl aqueous solution systems, at 25 degrees C, using the anionic sodium bis(2-ethylhexyl) sulfosuccinate (ACT) and zwiterionic phosphatidylcholine (PC) or mixtures of these surfactants. The isotropic single phase of water-in-oil (W/O) microemulsions (MEs) is shown in the phase diagram and their viscosity reported. ME samples containing small amount of surfactant exhibit slightly higher viscosity than pure SBO, and were used in the solubilization of small water soluble molecules. NaCl enhances the area of the ME phase and MEs with different surfactant composition exhibit different induction time as obtained from tests of oxidative stability, and so are the MEs enriched with ascorbic acid, folic acid and FeSO4, with the latter exhibiting lower stability. The so prepared enriched soy bean oil has potential application in food industry since the surfactants are food grade. (C) 2007 Elsevier B.V. All rights reserved.

Isolation and identification of mycobacteria from livestock specimens and milk obtained in Brazil

The prevalence of Mycobacterium bovis and other mycobacterial species in livestock specimens and milk was evaluated. An emphasis was placed upon the distribution of these organisms in milk that is readily available to the public that was either untreated, pasteurized, or treated using ultra high temperature. Twenty-two pathologic specimens from livestock (bovine, swine and bubaline) in five Brazilian states and 128 bovine milk samples from retail markets in the State of São Paulo were examined for mycobacteria. Identification was made by classical biochemical tests, thin layer chromatography of mycolic acids and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Mycobacteria were isolated from 15 (68.2%) caseous lesions and from 23 (18%) milk samples. Eleven isolates were identified as M. bovis, and the remaining 27 nontuberculous mycobacterial isolates were represented by five species and six unidentified rapidly growing mycobacterial strains. The data demonstrate that animal products in Brazil are frequent reservoirs of mycobacteria and may pose a risk to the public.

Occurrence of toxigenic Escherichia coli in raw milk cheese in Brazil

Pesquisou-se a ocorrência de Escherichia coli toxigênica, em queijo produzido com leite não pasteurizado, na Região Centro Oeste do Brazil. Foram utilizados 50 queijos adquiridos em diferentes supermercados. As amostras isoladas foram classificadas por sorogrupo, avaliadas em relação à sensibilidade para 13 agentes antimicrobianos e submetidas à reação em cadeia da polimerase para a presença de genes característicos de E. coli verotoxigênica (VTEC) e enterotoxigênica (ETEC). E. coli foi recuperada em 48(96,0%) dos queijos. Foram identificados os sorogrupos O125 (6,0%), O111 (4,0%), O55 (2,0%) e O119 (2,0%). Três (6,0%) amostras de E. coli foram classificadas como VTEC e uma (2,0%) como ETEC. Os maiores índices de resistência foram verificados para: cefalotina (60,0%), ácido nalidíxico (40,0%), doxiciclina (33,0%), tetraciclina (31,0%) e ampicilina (29,0%).
