Bacterial nanocells 0.2-0.3 micron in size and hundreds of a cubic micron in volume have been revealed in natural habitats and obtained in pure cultures. The taxonomic analysis of naturally occurring nanobacteria showed that they belong to the known taxa of the kingdom Eubacteria. The results of the cytological investigation of nanocells suggest that they are universally formed in response to stress impacts.
We studied metabolites synthesized by Bacillus subtilis strains, including the type strain of B. atrophaeus and phenotypically similar cultures. These metabolites were presented by polyene antibiotics with conjugated double bonds. Hexaenes from study strains inhibited the growth of phytopathogenic fungi Fusarium culmorum, F. sporotrichiella, F. oxysporum, Botrytis sorokiniana, Alternaria tenuis, and Phytophtora infestans. The degree of growth inhibition depended on the test fungus.
The descriptions of strains assigned to the species Halobacterium distributum were supplemented with the results of chemo-and genotaxonomic studies. According to these data, H. distributum VKM B-1733, which was hitherto regarded as the type strain of H. distributum, cannot be assigned to this species. Instead, strain H. distributum VKM B-1739 is proposed as the type strain. It is also suggested that strain VKM B-1954 should be transferred to H. distributum.
