“…Many studies have been undertaken to define the optimal culture and nutritional requirements for lipase production by submerged culture. Lipase production is influenced by the type and concentration of carbon and nitrogen sources, the culture pH, the growth temperature, and the dissolved oxygen concentration (Elibol and Ozer, 2001). Lipidic carbon sources seem to be generally essential for obtaining a high lipase yield; however, a few authors have produced good yields in the absence of fats and oils.…”

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

Abstract. The present investigation was carried out to evaluate the effect of different growth conditions on lipase production by Aspegillus niger. The extracellular lipase producing fungus was isolated from spent bleaching earths. Optimizations of physical and chemical parameters were done for maximum lipase production using this isolate. Growth of the organism and lipase production were measured usig varying pH (4 -9), incubation temperature (20 -30 °C), incubation time (8 -80 hrs.), carbon sources, nitrogen sources, and shaking speed. Enhanced lipase production was observed at 24 °C, pH 7 and after 72hrs of incubation. Olive oil 5 % was observed as the most effective carbon source and Yeast extract 1.0 % as the most effective nitrogen source for lipase production. The optimum shaking value to get maximum lipase activity by Aspergillus niger was 200 rpm.

ABSTRACT:Lipase is an important of extracellular thermostable enzyme that has received considerable attention for potential use in the food industry. Hence to achieve large scale production of gram positive and negative organism is commercially important lipase enzyme under the fermentation. Lipases are produced by microorganisms such as bacteria and fungi. However, we have focused on bacterial microbial lipases were economically importance of several properties. The present studies of the goals of this paper were isolation and identification of lipase producing bacteria from biogas producing power plant waste volatile substances as sources. Optimization of the experimental conditions for the maximal amount of enzyme production was performed.
