  • Abstract The lipase from the Antarctic psychrophilic bacterium Psychrobacter immobilis B10 shows a very limited thermal stability when compared to the lipase from a mesophilic strain of Pseudomonas aeruginosa . The thermal dependence of its activity is shifted by at least 30 °C towards low temperatures and its activation energy is reduced by a factor of 2. The three-dimensional model of the P. immobilis lipase reveals several features typical of cold-adapted enzymes: a very low proportion of… CONTINUE READING
