摘要

PROBLEM TO BE SOLVED: To provide a DNA segment involved in biosynthetic production of sphingan polysaccharides.SOLUTION: The present invention relates to DNA segments isolated from Sphingomonas sp. and involved in the biosynthetic production of sphingan polysaccharides to increase the production of the polysaccharide in engineered microorganisms. The present invention also relates to methods of engineering strains of Sphingomonas to produce bacteria which are hyperproducers of sphingan, methods of identifying and utilizing DNA fragments useful to enhance production of sphingan in bacteria and the hyperproducer bacteria.
