| Abstract Our objective was to characterize the protease enzymatic activity and its isoenzymes on cacao cultivars PH 16 and TSH 1188, produced in southern Bahia, linking it to the conditions of the fermentation process. Proteases were extracted and semi-purified, their activities determined changing substrate, pH and temperature, and the values compared with the parameters of fermentation (pH and temperature), and yet determined the kinetic parameters and the activity of its isoenzymes: aminopeptidase, carboxypeptidase and endoprotease. In the experimental conditions, differences in protease activities were shown as to different cocoa cultivars on various conditions. The albumin stands out as the preferred enzyme substrate, in a pH range between 3 and 6... |

| The abundance and composition of microbial communities were investigated during 2007 in Marennes Oleron Bay (France) in order to characterize the biological relationships governing the planktonic food web. Compared to the results of previous years, there was a lower abundance and a lower magnitude of variations in autotrophic and heterotrophic microbial entities in 2007. Using a Spearman rank correlation analysis, a significant link for biological abundance was only noted between bacteria and ciliates. However, an interesting relationship was highlighted between chlorophyll a and bacterial aminopeptidase and beta-glucosidase exoenzymatic activities. Two characteristic periods of virus-bacteria uncoupling were observed in spring and autumn 2007. Using... |
