General description

Lipase is produced by several animals, microbes, and plants. Lipase from Mucor sp. is a fungal lipase. It is a member of the serine hydrolase family.

Application

Lipase from Mucor miehei can be used to drive the synthesis of flavor esters.
Lipase from Mucor miehei has been used in a study to assess the nonthermal effect of microwave irradiation in nonaqueous enzymatic esterification. It has also been used in a study to investigate the hydrolysis of virgin coconut oil using immobilized lipase in a batch reactor.
Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.

Biochem/physiol Actions

Mucor miehei lipase hydrolizes triglycerides and catalyzes the synthesis of esters from glycerol and long-chain fatty acids in vitro. Tri-, di-, and monoglycerides are hydrolyzed (in decreasing order of rate).
Microbial lipase has a wide industrial application due to its stability, broad substrate specificity, and selectivity. It may be used in the synthesis of biosurfactants and finds application in organic chemical processing, dairy industry, oleochemical industry, detergent formulations, paper, cosmetics, nutrition, and the pharmaceutical industry.

Unit Definition

One unit will hydrolyze 1.0 microequivalent of fatty acid from a triglyceride in 1 hr at pH 7.7 at 37 °C using olive oil.

Analysis Note

Protein determined by biuret.

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

Steady-state and time-resolved fluorescence-quenching measurements have been performed to study multitryptophan lipase from filamentous fungus Rhizomucor miehei. Using the steady-state acrylamide fluorescence quenching data and the fluorescence-quenching-resolved-spectra (FQRS) method, the total emission spectrum of native ("closed-lid") lipase has been decomposed

A Photobacterium strain, M37, showing lipolytic activity, was previously isolated from an intertidal flat of the Yellow Sea in Korea and identified as Photobacterium lipolyticum sp. nov. In the present study, the corresponding gene was cloned using the shotgun method.
