Assessment of actinobacteria role in activity of deep-water endemic amphipod species belonging to the genus Ommatogammarus

The aim of present study was to reveal the associations between the actinobacteria strains and Lake Baikal deep-water endemic amphipods. During the study forty-two actinobacteria strains were isolated from the amphipods belonging to the genus Ommatogammarus ( O. albinus and O. flavus ) which were caught from the depth 80 - 200 m. The analysis of part of the gene 16S rRNA revealed that obtained strains belonging to the genera Streptomyces, Micromonospora, and Pseudonocardia. The results of the investigation display that actinobacteria that produce antimicrobial compounds inhabit the organism of amphipods from the Ommatogammarus genus. It is assumed that actinobacteria might effect the metabolism of deep-water amphipod-scavengers. Besides, actinobacteria obtained from Lake Baikal endemic amphipods have potential pharmaceutical applications as the source of antibiotics. They also enlarge our understanding of relationships between microorganisms and endemic amphipods.
