Lipases are the most pliable biocatalyst and bring about a wide range of bioconversion reactions, such as hydrolysis, interesterification, esterification, alcoholysis, acidolysis and aminolysis that play a key role in fat digestion by cleaving long-chain triglycerides into polar lipids and these Lipases (triacylglycerol acylhydrolases, EC catalyze the hydrolysis and the synthesis of esters formed from glycerol and long-chain fatty acid and they are ubiquitous enzymes which catalyze the hydrolysis of triacylglycerols to glycerols and free fatty acid. Lipases have been utilized for fat modification, fragrance development in dairy product and for the synthesis of personal care product, oil industry, dairy industry, pharmaceuticals and bakery industry and cosmetics. The most important microbial lipase-producing strains for submerged and solid-state fermentations are reviewed as well as the main substrates, including the use of agroindustrial residues. Current process techniques (batch, repeated-batch, fed-batch, and continuous mode) are discussed and the importance of lipase catalyzed fat splitting process, kinetics, deactivation kinetics, pre-purification and novel purification technologies.
