WIPO Patent Application WO/2020/135893

A1

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 300U/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.
