“…The BZR 336g strain was originally isolated from a winter wheat rhizoplane, and the plant source was grown in the Krylovsky district of the Krasnodar region in Russia. The strain was described previously as Bacillus subtilis BZR 336g (according to phenotyping and 16S rRNA gene analysis data) ( 6 ) and was placed in the Departmental Collection of Useful Microorganisms for Agricultural Purposes (accession number RCAM01729) as a highly effective producer of hydrolytic protease and lipase ferments and as a suppressor of common crop phytopathogens, such as Fusarium graminearum , Fusarium culmorum , Microdochium nivale , and Pyrenophora tritici-repentis ( 7 , 8 ). The BZR 336g strain has demonstrated commercial promise as a biological agent ( 9 ) for crop pest control ( 10 ).…”

Bacillus velezensis strain BZR 336g is a plant growth-promoting rhizobacterium isolated from a winter wheat rhizoplane from the Krasnodar region in Russia. In this study, we report the genome, including genes with known phenotypic function, i.e., the biosynthesis of secondary metabolites with fungicidal and plant growth-promoting activities. We sequenced and analyzed the complete BZR 336g genome using two different DNA preparation methods to help us better understand the origin of the antimicrobial and antifungal abilities and to weigh the biocontrol properties of this strain.

BACKGROUND: Human infectious diseases caused by antibiotic-resistant bacterial pathogens present a serious problem for clinical medicine. Causative agents of nosocomial infections, such as Escherichia coli, Klebsiella pneumoniae, Enterobacter spp., are the most common among them. An active search for antimicrobial agents that can effectively combat drugresistant pathogens is underway. Antimicrobial substances of bacterial origin are of particular interest. Promising sources of microorganisms with antibiotic properties are natural sources: Soil, water, plants, etc. AIM: The purpose of this work is to screen and characterize the antagonistic properties of microorganisms isolated from natural sources in connection with the creation of new pharmaceutical substances. METHODS: The material for the isolation of microorganisms was the soil, water bodies, and plant objects of various municipal districts of the Kemerovo Region. Identification of the isolated microorganisms was carried out using the methods proposed in the directory “Bergey’s Manual of Determinative Bacteriology” and in the monograph Nesterenko et al. The selection of strains from soil samples was carried out according to standard methods described in “Methods of soil microbiological control. Methodical recommendations,” cultural-morphological properties of isolates were studied using conventional microbiological methods. RESULTS: The following results are obtained: (1) Lactic acid bacteria and other microorganisms antagonists from natural sources were isolated: Soil, water bodies, and plant objects; 20 isolates were isolated, their cultural and morphological properties were studied; isolated microorganisms were found to belong presumably to the genera Bacillus, Leuconostoc, Pedio-coccus, Lactobacillus, and Bacteroides; (2) Antimicrobial properties of lactic acid bacteria and other antagonistic microorganisms isolated from natural sources on solid and liquid nutrient media were studied; (3) 12 strains of 20 isolates with maximum antimicrobial properties were selected for further studies. CONCLUSION: Further research on the biochemical properties of lactic acid bacteria and other antagonist microorganisms isolated from natural sources, the study of antibiotic resistance of lactic acid bacteria and other antagonist microorganisms isolated from natural sources, as well as other more detailed studies will be conducted with selected 12 strains with maximum antimicrobial properties.

It was also patented as a prospective biological agent for crop protection and control of phytopathogenic fungi (10,11).…”
