Thermus parvatiensis RL(T) sp. nov., Isolated from a Hot Water Spring, Located Atop the Himalayan Ranges at Manikaran, India.

ABSTRACT: A Gram negative, yellow pigmented, rod shaped bacterium designated as RL(T) was isolated from a hot water spring (90-98 °C) located at Manikaran in Northern India. The isolate grows at 60-80 °C (optimum, 70 °C) and at pH 7.0-9.0 (optimum pH 7.2). Phylogenetic analysis of 16S rRNA gene sequences and levels of DNA-DNA relatedness together indicate that the new isolate represents a novel species of the genus Thermus with closest affinity to Thermus thermophilus HB8(T) (99.5 %) followed by Thermus arciformis (96.4 %). A comparative analysis of partial sequences of housekeeping genes (HKG) further revealed that strain RL(T) is a novel species belonging to the genus Thermus. The melting G+C content of strain RL(T) was calculated as 68.7 mol%. The DNA-DNA relatedness value of strain RL(T) with it
