Abstract
Arthrobacter viscosus
NRRL B-1973 produces its viscous extracellular polysaccharides (EPS) when grown on media containing xylose or enzymatic xylan hydrolysates. Crude EPS formation from xylose averaged 12 g/liter when initial culture pH was adjusted to 8.0 and total nitrogen was limited to 0.03%. Purified EPS from pentose and hexose substrates were analyzed for their monosaccharide, acetyl, and uronic acid components, intrinsic viscosities, and average molecular masses. Differences were apparent in degrees of acetylation, molecular masses, and intrinsic viscosities of the heteropolysaccharides produced on different carbon sources.
