Gordoniaceae

Abstract

The phylogenetic position of the newly isolated bacterial strain of the Gordoniaceae family had been determined. The object of the research was a strain isolated from soil biota the Ufa industrial zone. The strain was able to utilize chlorophenoxyaromatic compounds. The investigation was done by the comparative analysis of the 16S rRNA gene nucleotide sequences. Sequencing of the amplified 16S rRNA gene was performed by F. Sanger. The interpretation of the phylogenetic relationships between sequences was carried out by the neighbor-joining method. The strain was previously attributed to the Actinobacteria assigned to the established cultural, morphological, physiological and biochemical characteristics. The Actinobacteria systematicsis actively reviewed from the point of phylogeny. According to the phylogenetic tree constructed on the nearly complete 16S rRNA gene nucleotide sequence the strain have been identified as a member of the genus Gordonia belongs to the family Gordoniaceae order Corynebacteriales phylum Actinobacteria. The results of the study supplement data of the genus Gordonia representatives. The genus Gordonia separated into its own taxon from the genus Rhodococcus based on biochemical and phylogenetic characteristics [11, с. 341]. Today due to the active phylogenetic studies more than 20 species of bacterial genus Gordonia have been found. The genus Gordonia includes strains capable of producing carotenoids, degradation of aliphatic and aromatic hydrocarbons, halogenated aromatic compounds, benzothiophene, nitrile, polyisoprene, xylene and coal and crude oil biodesulfatation. The classified in this study strain Gordonia sp. can be applied for environmental bioremediation methods development.
