High-level recombinant protein production with Corynebacterium glutamicum using acetate as carbon source.

ABSTRACT: In recent years, biotechnological conversion of the alternative carbon source acetate has attracted much attention. So far, acetate has been mainly used for microbial production of bioproducts with bulk applications. In this study, we aimed to investigate the potential of acetate as carbon source for heterologous protein production using the acetate-utilizing platform organism Corynebacterium glutamicum. For this purpose, expression of model protein eYFP with the promoter systems T7lac and tac was characterized during growth of C. glutamicum on acetate as sole carbon source. The results indicated a 3.3-fold higher fluorescence level for acetate-based eYFP production with T7 expression strain MB001(DE3) pMKEx2-eyfp compared to MB001 pEKEx2-eyfp. Interestingly, comparative eyfp expression st
