Succinoglucan, a succinylated polysaccharide produced by Alcaligenes faecalis var. myxogenes 1OC3, was partially hydrolyzed with acid. Fractionation of the neutral oligosaccharides gave cellobiose, gentiobiose, laminaribiose, laminaritriose, 6-O-β-laminaribiosylglucose, 6-O-β-laminaritriosylglucose, and 3-O-β-cellobiosylgalactose, confirming the previous results that the polysaccharide consists of β-(1→3)-linked, (1→4)-linked and (1→6)-linked D-glucose residues, and β-(1→3)-linked D-galactose residues. Possible structural features of succinoglucan were discussed on the basis of the above and previous results obtained by Smith degradation.
