The saccharides from the strains of Xanthomonas were all composed of unbranched, linear (1.2)-β-D-glucosaccharides with degrees of polymerization (DPs) of 8 to about 20, and a cyclic (1.2)-β-D-glucan (DP 16) containing one (1.6)-linkage and one α-linkage. The saccharides produced by the five strains of E. coli and four strains of K. pneumoniae were glucans with branches at O-6, and DPs of 10 to 15, whereas one strain of K. pneumoniae produced unbranched linear (1.2)-β-D-glucosaccharides with DPs of 6 to about 20. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-132-9-2443
