The isolation and structural characterization of exopolysaccharides (EPSs) synthesized by Pseudomonas species has been an integral part of a program in this laboratory with the goal of possible commercialization of these polymers. The EPSs which we have characterized to date were all isolated from p

β¦ Synopsis
Pseudomonas rnffrgi~~f~ is a phytopathogeni~ bacterial species that is a causative agent of soft rot in stored fruits and vegetables. Work in our laboratory has indicated that strains of this species are heterogeneous with respect to the acidic exopolysaccharides (EPS) they produce. We have recently characterized' the acidic EPS from strain HT041B as: --, 3)-/3-~-C3cp-(l + 3%a-D-Galp-(1 + * Mention of brand or firm names does not constitute an endorsement by the US Department of Agriculture over others of a similar nature not mentioned.

Mild acid degradation of the Pseudomonas fluorescens strain ATCC 49271 lipopolysaccharide resulted in a core oligosaccharide containing D-glucose, 2-acetamido-2-deoxy-D- glucose, 2-(L- alanylamino)-2-deoxy-D-galactose, 2-acetamido-2,6-dideoxy-D-glucose (QuiNAc), 2-acetamido- 2,6-dideoxy-L-galactose
The structure of an exopolysaccharide from Rhizobium sp. strain ANU280 (derivative of the broad host-range strain NGR234) has been determined. Fragments generated by partial acid hydrolysis were fractionated by sequential ionexchange and gel chromatography, and their structures were assigned by 13C-
