GENE 16S RRNA SEQUENCE PHYLOGENETIC ANALYSIS OF LYSINE PRODUCERS STRAINS
Abstract
The phylogenetic relationships of strainsproducers of essential amino acids of aspartate family Brevibacterium sp. UCM Ac-674 (Brevibacterium sp. 90), Brevibacterium sp. IMV Ac-5004 (Brevibacterium sp. 90H), Brevibacterium sp. UCM Ac-675 (Brevibacterium sp. E531), mutant strain Brevibacterium sp. IMV B-7447 from the «Collections strains and lines of plants for food and agricultural biotechnology SO “Institute for Food Biotechnology and Genomics” of National Academy of Sciences of Ukraine were investigated. The affiliation strain Brevibacterium sp. IMV B-7447 to the genus Brevibacterium within the sequences of the genes based on 16S rRNA was confirmed. The dendogram of phylogenetic relationships of studied strains and related strains Brevibacterium from database GenBank was constructed. It was shown that by the criterion of homology gene sequences based on 16S rRNA the investigated strains-producers belong to three phylogenetic groups. It was established that the mutant strain Brevibacterium sp. ІMV B-7447 has no analogues in the database GenBank.
