Abstract

A high molecular weight polysaccharide was isolated from ATCC 19213 cultured on a fructose mineral salts medium. This polymer was a heteropolysaccharide composed of -glucose, -xylose, -galactose and -arabinose in molar concentrations of 7.7:1.1:1.0:0.6, respectively. The polysaccharide neither bound concanavalin A nor formed a coloured complex with iodine, distinguishing it from many of the glucans isolated from other sporeformers. The concentration of the polymer decreased during forespore development, suggesting that it served as a carbon storage compound for use during formation of the spore.
