Advances in transcription regulators of bacterial exopolysaccharides biosynthesis

Abstract:

Bacterial exopolysaccharides (EPS) are widely used in food, pharmaceutical, and chemical fields due to their unique physicochemical properties and physiological activities. Bacterial EPS such as xanthan gum, gellan gum, and thermal gel are widely applied and favored in food industry. Transcriptional regulators can regulate the expression of eps genes at transcription level to affect bacterial EPS biosynthesis. Moreover, the regulatory mechanism of most reported EPS transcriptional regulators has not been elucidated. This review summarizes the progress of bacterial EPS transcriptional regulators in recent years and focuses on the research methods and regulatory mechanisms, in order to provide reference for transcription regulation research of bacterial EPS.
