β-galactosidase GALA from Bacillus circulans with high transgalactosylation activity. [PDF]
Bioengineered, 2021 β-galactosidase catalyzes lactose hydrolysis and transfers reactions to produce prebiotics such as galacto-oligosaccharides (GOS) with potential applications in the food industry and pharmaceuticals. However, there is still a need for improved transgalactosylation activity of β-galactosidases and reaction conditions of GOS production in order to ...
