The biological properties of the exopolysaccharide (EPS) of the Ancylobacter abiegnus Z-0056 bacteria (ancylan) were studied. The influence of this EPS on the natural-habitation microorganisms Ancylobacter abiegnus (Singulisphaera mucilaginosa Z-0071, Xanthobacter xylophilus Z-0055) and on test strains of several microorganisms (Pseudomonas aeruginosa 27533, Escherichia coli 01, Staphylococcus aureus 209, Bacillus cereus 8035, and Candida albicans 230) was explored. The exopolysaccharide under study in a concentration of 1 g/L was shown to render positive effect on the growth of some bacteria, including the producent itself (Ancylobacter abiegnus Z-0056). The influence of the EPS on the cells of Colpoda stenii infusorians [5] and laboratory animals (while mice) was studied. According to our data, it can be supposed that the A. abiegnus Z-0056 bacteria produce their exopolysaccharide for protection from being eaten by protozoa and as a reserve nutrient.
