Lipases from psychrotropic antarctic bacteria
Properties of lipases excreted by 4 psychrotropic Moraxella strains from antarctic sea water have investigated. Despite an optimal cell generation time at 25°C, maximal lipase excretion essentially occurs at low temperatures. These enzymes are characterized by a shift of the apparent optimal activit...

Properties of lipases excreted by 4 psychrotropic Moraxella strains from antarctic sea water have investigated. Despite an optimal cell generation time at 25°C, maximal lipase excretion essentially occurs at low temperatures. These enzymes are characterized by a shift of the apparent optimal activity towards low temperatures, by a reduction of the activation energy value and by a decrease in heat stability. These lipases are associated with lipopolysaccharides, forming high molecular weight complexes. One of the selected strain is able to express the antibiotic resistances carried by RP4, at both 4 and 25°C. |
