sp. nov., isolated from arctic alpine soil Free

Abstract

A Gram-stain-negative, aerobic, motile rod-shaped bacterium, designated 6-67, was isolated from a soil sample collected from Longyearbyen, Svalbard. Its taxonomic position was investigated by genotypic, phenotypic and chemotaxonomic analyses. This isolate grew at 4–28 °C (optimum, 20 °C), at pH 5.0–9.0 (optimum, pH 7.0) and with 0–0.2 % (w/v) NaCl. Strain 6-67 contained Q-8 as a major respiratory quinone and MK-7 as a minor component; the major fatty acids were summed feature 3 (C 6 and/or C 7) and C. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, two unidentified phospholipids and one unidentified aminophospholipid. The polyamines were putrescine and 2-hydroxyputrescine. 16S rRNA gene sequence analysis indicated that the novel strain 6-67 belonged to the family within the class . The DNA G+C content of strain 6-67 was 56.21 mol%. On the basis of phylogenetic, physiological and chemotaxonomic data, strain 6-67 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 6-67 (=CCTCC AB 2015162=KCTC 42986).
