Abstract

A Gram-stain-negative, rod-shaped, red-pigmented bacterium (MDT1-10-3) was isolated from Midui glacier in Tibet, China. Cells were aerobic and psychrotolerant (growth occurred at 4–25 °C). Phylogenetic analysis based on 16S rRNA gene sequences indicated that it was a member of the genus , with MCC P1 (96.7 % similarity) as its closest phylogenetic relative. MK-7 was the predominant respiratory menaquinone. The major cellular fatty acids were summed feature 4 (iso-C I and/or anteiso-C B), summed feature 3 (Cω6 and/or Cω7), Cω6, iso-C, iso-C and Cω5. The predominant polar lipids were phosphatidylethanolamine, two unidentified aminophospholipids, one glycolipid and four unidentified lipids. The G+C content of the genomic DNA was 49 mol%. On the basis of the phenotypic characteristics and phylogenetic analysis, strain MDT1-10-3 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is MDT1-10-3 ( = CGMCC 1.9789 = NBRC 109705).
