Bacterial biome of sugar beet with black root of sugar beet

Abstract

The purpose. To isolate and identify bacteria in structure of biome of plants of sugar beet, contaminated with black root of sugar beet. Methods. Field — for sampling plants with disease symptoms; laboratory (microbiological and phytopathological) — for allocation of bacteria in pure culture, determination of their disease-inciting power; biochemical — for determination of properties of the isolated bacteria. Results. Bacteriological analysis of samples of plants of sugar beet with typical symptoms of black root of sugar beet is carried out. Conclusions. Except for the basic causal organisms of black root of sugar beet, in structure of biome of plants of sugar beet, contaminated with black root of sugar beet they fixed presence of bacteria of stem Bacillus and pectolytic-active bacteria of Pectobacterium carotovorum which are capable to initiate putrefaction or reinforce pathological process caused by other microorganisms.
