Arcticibacter pallidicorallinus sp. nov. isolated from glacier ice

Abstract

A Gram-stain-negative, rod-shaped bacterium (strain Hh36T) was isolated from the No. 1 glacier in Xinjiang, north-west China. Colonies of strain Hh36Twere pink, convex and round on PYG medium plates. Strain Hh36T was able to grow at 4-30 °C and pH 6.0-8.0. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Hh36T was related to members of the genus Arcticibacter. The major cellular fatty acids of the novel strain were iso-C15: 0, summed feature 3 (C16: 1ω6c and/or C16: 1ω7c) and iso-C17: 0 3-OH. The G+C content of the genomic DNA was 44.0 mol%. On the basis of phenotypic characteristics and phylogenetic analysis, strain Hh36T is considered to represent a novel species of the genus Arcticibacter, for which the name Arcticibacter pallidicorallinus sp. nov. is proposed. The type strain is Hh36T (=CGMCC 1.9313T=KCTC 32542T).
