STUDY ON BACILLUSPRODUCING ALKALINE LIPASE ISOLATED FROM MANGROVES

Abstract

Lipases are enzymes that have been extensively usedin the processing industries and in medicine worldwide. In fact lipases take the secondrank in enzyme production, after protease. Recently, there have been several new applications of lipase introduced such as industrial detergents, tanning industry, changing the chemicalstructure of molecules... In this study, we selected eight among 250 strains of bacteria isolated from mangroves that are capable of producing strong alkaline lipase. The lipase shows  high activity at pH 9, in 3 % salt concentration solution. All eight strains were identified as Bacillusspp. These bacteria actually possess meaningful applications in the processing procedures that require alkaline and saline conditions in the industry. The applications and characteristics of lipase were studied and discussed in detail
