The hydrolysis products of lactose (200 g/L) degraded by bG42-106. (a) Effects of temperature and enzyme concentration on the lactose hydrolysis for 24 h. (b) Time course of lactose hydrolysis (solid lines) and galacto-oligosaccharide synthesis (dash lines) at 60°C with different enzyme concentrations. The error bars represent the mean ± standard deviation of three replicates.
