Abstract
A fungal strain Beauveria species bearing accession number MTCC 5184 is disclosed. The process for the preparation of an enzyme mix including at least one enzyme selected from, but not limited to protease, carbohydrase, and lipase from the disclosed Beauveria species and uses of the enzyme mix in various areas also disclosed.
Claims8
A composition comprising:
- a protease enzyme and an organic solvent, wherein the protease enzyme is from a Beauveria species bearing accession number MTCC 5184, and the organic solvent comprises acetone, ethanol, isopropanol, methanol, butanol, chloroform, dimethyl sulfoxide (DMSO), or hexane;
- wherein the composition is prepared by a process comprising:
- a) culturing the Beauveria species in a medium comprising 0.15 to 80% of a carbon source, 0.15 to 80% of a nitrogen source, and an inducer, wherein the carbon and nitrogen sources are optionally inducers under aerobic conditions at a pH ranging from 5.0 to 9.0 and a temperature ranging between 15° to 32° C. for a period ranging between 2 to 7 days;
- b) harvesting the medium obtained in step (a);
- c) separating/extracting the protease enzyme from the harvested medium in liquid phase;
- and
- d) providing the protease enzyme obtained in step (c) with the organic solvent;
- wherein the protease enzyme in the composition has a greater residual activity (%) than a control sample comprising an identical concentration of the protease enzyme in water, after 1 hour at 50° C.;
- and
- wherein the protease enzyme is active in a pH range of 5.5 to 12, provides its maximum activity at 50° C., and is stable in a pH range of 3 to 11.
