Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to a high-activity α-galactosidase Aspergillus niger variant and its fermentation process on a solid substrate. Background technique

[0002] α-galactosidase is an enzyme that catalyzes the decomposition of α-galactosides into monosaccharides such as oligosaccharides, sucrose, and fructose, and is widely found in microorganisms, plants, and animals. α-Galactosidase has very important application value in all aspects of food and pharmaceutical industries. In the beet sugar industry, the raffinose in molasses is decomposed by α-galactosidase, which can not only increase the yield, but also improve the efficiency. In addition, it is also widely used in medicine and modification of polysaccharide gums. Studies in recent years have shown that this enzyme, as a specific exogenous feed enzyme, also has a broad application prospect in the feed industry. There are high levels of α-galactoside...
