Research on Curdlan Synthesized by Agrobacterium sp.ATCC31749

Abstract

Abstract: Curdlan is a high molecular β-1, 3-glucan with unique gel nature. Curdlan and it’s modified molecule were used as new materials applied widely in industries of food, pharmaceutics and chemical engineering, resulting in the growing of curdlan demand year by year. Agrobacterium sp. ATCC31749 is an efficient industrious strain for curdlan production. This review summarized the advance of the fermentation and physiology of curdlan biosynthesis of the strain. By combining with ATCC31749 genomic information and proteomics study, we focus on signal transduction and regulation, energy producing and metabolic pathway of this special polysaccharides biosynthesis ；then analyze the restriction factor for curlan synthesis and propose the strategies for how to improve the strain and optimize fermentation procedures.

Key words: Genomic information and proteomics, Curdlan biosynthesis, Regulatory mechanism
