One strain each of Xanthomonas campestris and 'Xanthomonas phaseoli', three strains of 'Xanthomonas oryzae', and five strains each of Escherichia coli and Klebsiella pneumoniae were found to produce a mixture of (1----2)-beta-D-gluco-oligosaccharides and/or low-Mr (1----2)-beta-D-glucans in their culture media. The saccharides from the strains of Xanthomonas were all composed of unbranched, linear (1----2)-beta-D-glucosaccharides with degrees of polymerization (DPs) of 8 to about 20, and a cyclic (1----2)-beta-D-glucan (DP16) containing one (1----6)-linkage and one alpha-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)-beta-D-glucosaccharides with DPs of 6 to about 20.
发现野油菜黄单胞菌和菜豆黄单胞菌各1株、稻黄单胞菌3株以及大肠杆菌和肺炎克雷伯菌各5株在其培养基中产生(1→2)-β-D-葡寡糖和/或低分子量(1→2)-β-D-葡聚糖的混合物。来自黄单胞菌菌株的糖类均由聚合度(DPs)为8至约20的无分支线性(1→2)-β-D-葡聚糖，以及含有一个(1→6)连接和一个α连接的环状(1→2)-β-D-葡聚糖(DP16)组成。5株大肠杆菌和4株肺炎克雷伯菌产生的糖类是在O-6位有分支且DPs为10至15的葡聚糖，而1株肺炎克雷伯菌产生的是DPs为6至约20的无分支线性(1→2)-β-D-葡聚糖。
