Structure of an exocellular beta-D-glucan from Pediococcus sp., a wine lactic bacteria.
Pediococcus sp. produces an exocellular slime containing exclusively D-glucose. The structure of the polysaccharide was determined by methylation analysis, Smith degradation, enzymic hydrolysis, and 13C-n.m.r. spectroscopy as having a trisaccharide repeating unit, ----3)-beta-D-Glcp-(1---- 3)-[beta-D-Glcp-(1----2)]-beta-D-Glcp-(1----.
