Presence of acetate and succinate in the exopolysaccharide produced by Zoogloea ramigera 115SLR

摘要

The extracellular acidic polysaccharide produced by Zoogloea ramigera 115SLR contains O-acetyl and O-succinyl groups, in addition to glucose, galactose and pyruvate already reported. Methylation analysis of both the native and the chemically modified zooglan showed that these O-acyl groups are attached to position 6 of a 4-substituted glucosyl residue and of a terminal glucose.
