Dynamic regulation of gut Clostridium-derived short-chain fatty acids

Short-chain fatty acids (SCFAs) are major products of intestinal microbial fermentation with beneficial effects for human health. The dynamic balance and real-time monitoring of endogenous SCFA biosynthesis are important for understanding their physiological functions. We discuss the promising future of applying CRISPRi genetic systems and biosensors for targeted SCFA improvement.
