Abstract:
Two extracellular polysaccharides from strains of Erwinia chrysanhemi Ech 1 and 9, phytopathogens of potatoes, have been isolated and purified. Both have similar compositions and other properties to that produced by strain SR 260, a phytopathogen of corn. These polysaccharides are composed of L-rhamnose, D-mannose, D-glucose, D-glucuronic acid in the ratio 3:1:1:1. Initial structural aspects of these polysaccharides are reflected in the 600 MHz 1H NMR spectra and the products of partial acid hydrolysis, which are presented for comparison.
