Isolation and identification of bacteria isolated from cabbage seeds in the Ulyanovsk region

Abstract

Bacteriosis caused by the bacterium Xanthomonas campestris is considered one of the most dangerous for cultivated plants. The problem is particularly sharp during favorable agricultural seasons for the development of pathogens. At the same time, effective and modern methods of combating these bacterioses are currently lacking for their effective control. One of the suggested solutions to this problem is the use of phage biopreparations, for which the activity towards “field” cultures of microorganisms is important. In this regard, 22 strains of Xanthomonas campestris bacteria were isolated from 36 samples of seed material. Despite the differences in the seed material, all the isolated strains had typical biological properties for the species and corresponded both to each other and to the reference strains used in work. At the same time, the pathogenicity of isolated microorganisms in relation to cabbage was established in 21 strains. Page layout
