[Progress in microbial production of prodigiosin].

Prodigiosin is an important natural red pigment that is produced as a secondary metabolite by microorganisms, and has great potential applications in the field of pharmaceutical development, environmental management and dye preparation. This paper reviews recent research progress in the production of prodigiosin by microbial fermentation, including discovery and modification of the prodigiosin-producing microorganisms, regulation and optimization of prodigiosin fermentation and extraction process, and resolution of biosynthetic pathway of prodigiosin and related transcriptional regulation. Finally, we discussed the future research directions in microbial production of prodigiosin.
