Source of Lipase

1. Lipase


The scientific name of lipase is triacylglycerol acylhydrolase, which can catalyze the hydrolysis reaction of fats and oils to produce fatty acids and glycerol. Lipase is a kind of enzyme, a protein substance composed of amino acids. Lipases are specific and only work on one type of fat. Lipases of different structures and the lipid substances that can act are also different.


2. The source of lipase


Lipase was first discovered in 1834. It is an extremely important metabolic enzyme in the organism and an indispensable enzyme in the metabolic process of the human body and the organism. With lipase, the fats and oils ingested by the human body and organisms can be absorbed by the intestines.


The industrial lipase is mainly derived from microbial fermentation. The lipase-producing fungi mainly include Aspergillus niger, Pseudomonas fluorescens, Geotrichum candidum Rhizopus, Candida cylindrica, Rhizopus nigricans, and Humicola multicoccus. , Penicillium arcuate Chromobacterium marcescens.


The main strain used to produce and extract lipase is Aspergillus niger, which adopts the method of liquid submerged fermentation. For lipase fermentation strains to be used in industrial production, their yield and enzyme quality must be the most concerned issues of major manufacturers.


Therefore, scientific researchers use mutagenesis technology to continuously act on lipase to cause its gene mutations and screen step by step, and finally obtain high-yielding strains that can be used in industrial production. The enzyme-producing capacity of high-yielding strains is dozens or even hundreds of times that of general strains.
