Halophilic enzymes especially esterase & lipases have a wide and varied industrial & biotechnological application in the present era. The ability of the halophilic bacteria to grow and produce enzymes over a very wide range of salinities make them very attractive for research and for the isolation of novel enzymes with unusual properties. Screening of novel extreme halophilic microorganism is very important for the production of novel enzyme. The bacterium Marinobacter Hydrocarbonoclasticus PSTZ used for the present study was previously isolated in our laboratory. Further work was carried out...
