Abstract
There is a growing trend to produce lipase from microorganisms owing to their commercial demand in various industries. Bacillus cereus has been shown to have extracellular lipase activity and high growth rates. This study explains the purification of microbial lipase to homogeneity by dialysis, precipitation and chromatography. The purified enzyme with 56kDa relative molecular mass exhibited the highest activity at 60°C (95.56U/ml) and pH 7 (124.50U/ml). The enzyme activity was highly promoted in the presence of K+ (136.17U/ml) and Zn++(133.07 U/ml), and SDS did not affect the enzyme activity, whereas in the company of triton X100 activity of lipase is maximum (23.90 U/ml). The enzyme activity was enhanced by using almond oil (120.00 U/ml) as a substrate. We deduce cheaper protocols for producing extracellular lipase via simple laboratory techniques, which could be a good insight for its production at the commercial level.
Keywords: Lipase; Bacillus cereus; chromatography; enzyme activity; purification.
