LOW POLYSACCHARIDE MICROORGANISMS FOR PRODUCTION OF BIOFUELS AND OTHER RENEWABLE MATERIALS

High cell density fermentations of wild-type organisms can result in increased viscosity due to the production of exocellular polysaccharides. Mutant microorganisms with a dry morphology, resulting from reduced exocellular polysaccharide formation, were isolated and characterized. The exocellular po...

Zusammenfassung:	High cell density fermentations of wild-type organisms can result in increased viscosity due to the production of exocellular polysaccharides. Mutant microorganisms with a dry morphology, resulting from reduced exocellular polysaccharide formation, were isolated and characterized. The exocellular polysaccharide composition for these modified microorganisms is shown to be different than the polysaccharide composition of the wild type microorganism. In addition to reduced exocellular polysaccharide formation, dry morphology mutants of multiple strains show reduced viscosity, improved oxygen mass transfer, and improved fatty acid fermentation yield on carbon.
