Lipases (triacylglycerol acylhydrolases, EC 3.1.1.3) catalyze the hydrolysis and the synthesis of esters formed from glycerol and long-chain fatty acids. Lipases occur widely in nature, but only microbial lipases are commercially significant. The many applications of lipases include speciality organic syntheses, hydrolysis of fats and oils, modification of fats, flavor enhancement in food processing, resolution of racemic mixtures, and chemical analyses. This article discusses the production, recovery, and use of microbial lipases. Issues of enzyme kinetics, thermostability, and bioactivity are addressed. Production of recombinant lipases is detailed. Immobilized preparations of lipases are discussed. In view of the increasing understanding of lipases and their many applications in high-value syntheses and as bulk enzymes, these enzymes are having an increasing impact on bioprocessing. D

A bacterium hydrolysing various organic materials including cellulose, protein, starch and lipid was isolated. The isolate was identified as Bacillus subtilis, and named Bacillus subtilis CK-2 in this paper. This bacterium showed optimal growth at 40~45℃, pH 6~9, and 0~3% of NaCl. B. subtilis CK-2 seemed to synthesis highly active autolysin. The hydrolytic enzymes produced by B. subtilis CK-2 were primary enzymes because extracellular enzyme activities varied similarly to the growth curve.The hydrolytic enzymes seemed to be stable at basic pH conditions. From these results, B. subtilis CK-2 was found to bea useful bacterial agent for composting, or for use in feed-production waste in agriculture, fishery, forest materials, livestock farming, and food.

“…Other valuable properties of most lipases are the ability of catalyzing enzymatic interesterification reactions rearranging a triglyceride molecule, and transesterification between oil compounds, alkyl or aryl esters, and alcohols [3]. Lipases can also be used to accelerate the degradation of fatty waste and polyurethane [4,5].…”
