Efficient media for high production of microbial lipase from Bacillus subtilis (BSK-L) using response surface methodology for enantiopure synthesis of drug molecules

Lipases are a multipurpose enzyme that holds a significant position in industrial applications due to its ability to catalyse a large number of reactions such as hydrolysis, esterification, interesterification, transesterification which makes it a potential candidate. It is also used for the separation of chiral drugs from the racemic mixture and this property of lipase is considered very important in pharmaceutical industries for the synthesis of enantiopure bioactive molecules. Assuming the tremendous importance of lipases, as stereoselective biocatalysts, in pharmaceuticals and various other commercial applications, industrial enzymologists have been forced to search for those microorganisms which are able to produce novel biocatalysts at reasonably high yield. In the present study microbial lipase was isolated from the water sample of pond at Katra, Jammu and Kashmir (India). This enzyme has shown wide specificity and higher enantioselectivity, which make it pharmaceutical important enzyme. To make it economical for industrial application, it was produced on cheap nutrient media using Response Surface Methodology and got maximum production. It was used for resolution of chiral drugs and the significant results obtained during the course of work shall have potential towards pharmaceutical industries.
