Isolation and Identification of Microvirga thermotolerans HR1, a Novel Thermo-Tolerant Bacterium, and Comparative Genomics among Microvirga Species.

ABSTRACT: Members of the Microvirga genus are metabolically versatile and widely distributed in Nature. However, knowledge of the bacteria that belong to this genus is currently limited to biochemical characteristics. Herein, a novel thermo-tolerant bacterium named Microvirga thermotolerans HR1 was isolated and identified. Based on the 16S rRNA gene sequence analysis, the strain HR1 belonged to the genus Microvirga and was highly similar to Microvirga sp. 17 mud 1-3. The strain could grow at temperatures ranging from 15 to 50 °C with a growth optimum at 40 °C. It exhibited tolerance to pH range of 6.0-8.0 and salt concentrations up to 0.5% (w/v). It contained ubiquinone 10 as the predominant quinone and added group 8 as the main fatty acids. Analysis
