The anaerobic mixed microbiote may be inhibited through different mechanisms: inhibition by product or substrate, by the physical characteristics of the medium (pH or temperature), and by inhibitory substances, organic or inorganic. Biological activity tests have been the most widely used, of different experimental procedures known, to evaluate the toxicity of various compounds in anaerobic pro...

A cold-active endoglucanase-producing bacterium was isolated from the Beaufort Sea of Arctic Ocean and identified as Pseudoalteromonas sp. ArcC09. Cellulolytic activity ArcC09 reached a maximum 60 U/mg when cultivated in ZoBell medium for 72 h at 15 °C. This purified endoglucanase, with molecular mass 28 kDa, exhibited pH 7.0 55 The endoglucanase 10% 36% its maximal even low temperatures 5 °C °...
