Abstract

For the first time, the article provides data on the history of the discovery and study of the endophytic bacterium Bacillus subtilis 26D (ARRIAM 128), the ground of the biofungicide Phytosporin-M, used in Russian crop production for more than 30 years. A brief analysis of the term endophyte in relation to bacteria, statistics of Russian scientific publications on endophytic bacteria are given. The cultural, morphological and biochemical properties of the strain, biological activity in relation to phytopathogenic fungi and bacteria, useful microorganisms, plants and animals are considered. The properties of modified endophyte strains and the perspectives of use bacteria B. subtilis 26D are described.
