ASPERGILLUS ORYZAE BLCY-006 STRAIN AND APPLICATION THEREOF IN PREPARATION OF GALACTOOLIGOSACCHARIDE

摘要

Provided are an aspergillus oryzae BLCY-006 strain and an application thereof in the preparation of a galactooligosaccharide. The strain produces β-galactosidase, and the enzyme activity can reach 300 U/ml after culturing and fermentation, which is more than 50% higher than traditional β-galactosidase activity. The enzyme also has lactose and glucose resistance properties.
