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 proce...

Lipases are placed only after proteases and carbohydrases in world enzyme market and share about 5% of enzyme market. They occur in plants, animals and microorganisms and are accordingly classified as plant, animal and microbial lipases. Wherever they exist, they function to catalyze hydrolysis of triglycerides to glycerol and fatty acid. Like carbohydrases and proteases, lipases of microbial o...

Due to the numerous applications of lipases in industry, there is a need to study their characteristics, because lipases obtained from different sources may present different properties. The aim of this work was to accomplish the partial characterization of lipases obtained through submerged fermentation and solid-state fermentation by two species of Aspergillus. Fungal strains were isolated fr...

Lipases (triacyl glycerol acylhydrolases, EC 3.1.1.3) belonging to the class Hydrolases catalyze hydrolysis of insoluble triacylglycerols (TAGs) to generate free fatty acids, mono and diacylglycerols and glycerol (Das et al., 2016). Lipases are found in both prokaryotes (bacteria and archaea) as well as in eukaryotes (animals, plants and fungi) (Cai-hong et al., 2008). The most broadly applied ...

Infants of women with gestational diabetes mellitus (GDM) are more likely to be born large for gestational age with a higher percentage body fat. Elevated maternal lipids may contribute to this. Placental lipases such as lipoprotein lipase (LPL), endothelial lipase (EL) and hormone sensitive lipase (HSL) are involved in transferring lipids from mother to fetus. Previous studies of expression of...

Lipases (triacylglycerol hydrolases, EC 3.1.1.3) are enzymes that hydrolyze triacylglycerol at the oil-water interface and liberate free fatty acids and glycerol (Dheeman et al., 2010). Lipases belong to the class of serine hydrolases (Sharma et al., 2009) and contains the consensus sequence G-X1-S-X2-G as the catalytic moiety, where G = glycine, S = serine, X1 = histidine and X2 = glutamic or ...

Microbial lipases are an important group of biotechnologically valuable enzymes, because of the versatility of their applied properties and ease of mass production. Lipases of microbial origin are widely diversified in their enzymatic properties and substrate specificity, which make them very attractive for industrial applications. This review describes the applications of microbial lipases in ...

Lipase-catalyzed ethanolysis of triolein was studied as a model for biodiesel production. Four lipases were immobilized on porous polypropylene, and ethanolysis reactions were carried out in methyl t-butyl ether. The reaction products were analyzed using gas chromatography. Three of the four lipases studied were efficient in the conversion of triolein to 2-monoolein, but slow in the final step ...
