EXTRACELLULAR MICROBIAL POLYSACCHARIDE PRODUCTION BY FERMENTATION ON WHEY OR HYDROLYZED WHEY

Abstract

ABSTRACT Several organisms have been screened for their ability to produce extracellular microbial polysaccharides when lactose or glucose: galactose (1:1) were used as the carbon source during fermentation. Organisms were selected from known gum producing strains (on glucose) of Alcaligenes, Xanthomonas, Arthrobacter, Zooglea , and others. Results indicate that all organisms studied can produce polymers from hydrolyzed lactose while only Alcaligenes viscosus and Zooglea ramigera produced a gum from whey, when using conditions as reported here.
