l-asparaginase has high application value in medicine and food industry, but the low yield limits its application. In this study, we designed a synthetic system in <i>Bacillus subtilis</i> to produce l-asparaginase by improving gene expression and optimizing the fermentation agitation speed. Gene expression was improved by respectively increasing transcription levels and translation speeds through screening promoters and RBS sequences. With the optimal promoter, P43, and the synthetic RBS sequen ...[more]
