Abstract:
Hyaluronic acid(HA)is a linear polysaccharide chain composed of alternating ?-1,4-glucuronic acid(GlcA)and ?-1,3-N-acetylglucosamine(GlcNAc)moieties.Construction of engineering strain has become the prevailing strategy for increasing yield and improving its quality,especially the molecular weight.Here the molecular mechanism of HA biosynthesis in Streptococcus strains was reviewed,involving fermentation strains,operon structure,crucial enzyme and construction of engineering strains.In addition,the prevalent problems in HA fermentation production were also discussed and the protocols were tentatively put forward for the upcoming research and industrial production.
