sp. nov., a psychrophilic bacterium isolated from glacial soil Free

Abstract

Strain RuGl7 was isolated from a soil sample collected at the periphery of the glacial Lake Roopkund in the Himalayan mountain range, India. Cells of RuGl7 were Gram-positive, aerobic, rod-shaped, motile and grew optimally between 15 and 18 °C. Cells of RuGl7 contained 2,4-diaminobutyric acid in the cell-wall peptidoglycan and the major menaquinones were MK-10, MK-11 and MK-12. The polar lipids present were diphosphatidylglycerol and phosphatidylglycerol and an unknown lipid and the major fatty acid was anteiso-C. Based on the above characteristics, strain RuGl7 was assigned to the genus . Strain RuGl7 shared a 16S rRNA gene sequence similarity of 97.0 and 99.0 % with JCM 13925 and JCM 1463, respectively. However, DNA–DNA relatedness values between strain RuGl7 and and were 28 and 23 %, respectively. Furthermore, strain RuGl7 exhibited several phenotypic and genotypic differences when compared with , and . Based on these differentiating characteristics, strain RuGl7 was identified as a novel species of the genus for which the name sp. nov. is proposed. The type strain is RuGl7 (=DSM 21065=JCM 15131).
