Abstract
Strains of Bacillus genus were isolated from soil samples in the permafrost region (Yakutia, Russia). The phenotypic characteristics of the strains are given. The analysis of the obtained data made it possible to assign them to the Bacillus cereus complex. PCR analysis made it possible to determine the profile of B. cereus toxin synthesis genes in the genomes of the studied strains. Genetic characterization was obtained by RAPD genotyping and using MLVA loci used for genotyping of the anthrax pathogen. The results of genotyping at different levels of resolution made it possible to differentiate the studied strains from the B. anthracis species and to show their intraspecific genetic differences and the degree of relationship. Whole genome sequencing was carried out, based on the data of which MLST genotyping was carried out, which revealed two known sequence types and one new one that is described for the first time in this work. The results we obtained are of practical importance and are extremely interesting from the point of view of the evolution and phylogeography of the B. cereus group, since the fact that strains were isolated from permafrost suggests that their age may be much older than expected.
期刊介绍:
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
