Effects of carbon and nitrogen source on DPEase production and cell growth. a Effect of different carbon sources on the production of DPEase in WB800-Cb. b Effect of different nitrogen sources on the production of DPEase in WB800-Ds. c Effect of different carbon sources on the production of DPEase in WB800-Cb. d Effect of different nitrogen sources on the production of DPEase in WB800-Ds. All tests were performed in triplicate, and the results are presented as the means ± standard deviation
