The effect of expression cassettes on enzyme activity. A The schematic diagram of promoter engineering in B. subtilis. B Comparison of crude enzyme activity of recombinant strains in flask fermentation. The transcription element has only one promoter, HpaII, as the original control. C Fed-batch fermentation of strain SspovG-srfA was performed to test total enzyme activity in a 5 L bioreactor
