Research Status and Progress on β-Galactosidase

Abstract:

β-Galactosidase is an important food biocatalyst，which possesses transglycosylation and hydrolysis of β-1，4 glycoside bonds. These catalytic have been widely used in galacto- oligosaccharides production and lactose hydrolysis. As an important member of glycoside hydrolase family，it has accumulated rich results on research of theory and application of β-galactosidase. In this paper，it is reviewed from perspectives of theory and application，including distribution of β-galactosidase in glycoside hydrolase family，theory of catalytic mechanism，progress on structure research，and development of specific functional. This article is intended to provide reference for further research on the catalytic mechanism regulation and the application development of β-galactosidase.
