The exopolysaccharide produced by a ropy strain of Pediococcus damnosus (2.6) in a semi-defined medium was found to be an homopolymer composed of D-glucose. On the basis of monosaccharide and methylation analysis, 1H, 13C, 1D and 2D NMR experiments the polysaccharide was shown to consist of repeating units with the following structure.

Rhizobium fredii HH103 produces extracellular signal molecules that are able to induce deformation of root hairs and nodule organogenesis of soybean. This strain produces a large variety of nodulation factors, consisting of a linear backbone of GlcNAc with different degrees of polymerization, bearing on the non-reducing residue various different N-acyl(More)
