Fig. 1From: Application of the thermostable β-galactosidase, BgaB, from Geobacillus stearothermophilus as a versatile reporter under anaerobic and aerobic conditionsTemperature (a) and pH (b) profiles of the BgaB expressed in E. coli. The Y-axis designates the relative β-galactosidase activity at different conditions temperature (a) and pH (b). Error bars indicate standard deviation calculated based on triplicate experiments. pH profile was assessed at 70 °CBack to article page
