Figure 3From: Discovery of novel enzymes with industrial potential from a cold and alkaline environment by a combination of functional metagenomics and culturing Temperature and pH profiles of β-galactosidases. Temperature (left) and pH (right) profile of crude extracts of the two β-galactosidases BGalI3H5 (dotted line) and BGalI17E2 (solid line) with ortho-nitrophenyl-β-galactoside (ONPG) as substrate. Error bars show standard deviations from triplicate experiments.Back to article page
