Effect of xylose utilisation and induction time in the xylose-inducible expression system. a Effect of induction time on the production of DPEase in WB800-Cb. b Effect of induction time on the production of DPEase in WB800-Ds. c Effect of xylose concentration on the production of DPEase in WB800-Cb. d Effect of xylose concentration on the production of DPEase in WB800-Ds. All tests were performed in triplicate, and the results are presented as the means ± standard deviation
