Abstract

The rapid development of new molecular methods and approaches, sequencing technologies, has provided new insights into genetic and structural features of bacterial genomes. Information about the genetic organization of metabolic pathways and their regulatory elements has greatly contributed to the increase in the number of studies related to the construction of new bacterial strains with improved characteristics. In this study, the entire genome of the producing strain Clostridium sp. UCM В-7570 from the “Collection of producing strains of microorganisms and plant lines for food and agricultural biotechnology” of Institute of Food Biotechnology and Genomics of the National Academy of Sciences of Ukraine was sequenced and characterized. The genome was assembled into the scaffold with a total size of 4,470,321 bp and a GC content of 29.7%. The total number of genes identified was 4262, of which 4057 encoded proteins, 10 were rRNA operons, and 80 were tRNA genes. The genes of the sequenced genome encoding enzymes involved in butanol fermentation were found and analyzed. They were organized into cluster structures, and their protein sequences were found to be similar to the corresponding strains of C. acetobutylicum, C. beijerinckii, and C. pasteurianum type strains with the highest similarity to the latter. Thus, Clostridium sp. UCM В-7570 producing strain was identified as C. pasteurianum and suggested for metabolic engineering purposes.
