sp. nov., isolated from a soil sample from Union Glacier, Antarctica No Access

Abstract

A Gram-stain-positive, catalase-positive, non-motile bacteria, with a rod–coccus cycle (designated as EH-1B-1) was isolated from a soil sample from Union Glacier in Ellsworth Mountains, Antarctica. Strain EH-1B-1 had an optimal growth temperature of 28 °C and grew at pH 7–10. The major cellular fatty acids were anteiso-C, iso-C, C and anteiso-C. The G+C content based on the whole genome sequence was 63.1 mol%. Strain EH-1B-1 was most closely related to members of the genus , namely and . The strain grew on tryptic soy agar, Reasoner’s 2A agar, lysogeny broth agar and nutrient agar. The average nucleotide identity and digital DNA–DNA hybridization values between strain EH-1B-1 and its closest reference type strains ranged from 78 to 88 % and from 20.9 to 36.3 %, respectively. Based on phenotypic, chemotypic and genotypic evidence, it is proposed that strain EH-1B-1 represents a novel species of , for which the name sp. nov. is proposed, with strain EH-1B-1 (RGM 3386=LMG 32961) as the type strain.
