sp. nov., isolated from fragmentary rock Free

Abstract

A red-pigmented, Gram-stain-negative, rod-shaped, aerobic bacterium, designated strain CCM 8646, was isolated from stone fragments in James Ross Island, Antarctica. Strain CCM 8646 was able to grow from 10 to 40 °C, in the presence of up to 1 % (w/v) NaCl and at pH 7.0–11.0. Analysis of the 16S rRNA gene sequence placed strain CCM 8646 in the genus with the closest relative being H359 (97.07 % 16S rRNA gene sequence similarity). The digital DNA–DNA hybridization values between strain CCM 8646 and H359 were low (21.30±2.34 %). The major quinone was menaquinone MK-7. The polar lipids comprised phosphatidylethanolamine, an unknown aminoglycolipid and six unknown polar lipids. The G+C content of strain CCM 8646 was 51.54 mol%. On the basis of phenotypic, chemotaxonomic and genotyping results, strain CCM 8646 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is CCM 8646 (=LMG 29438).
