A novel aerobic bacterial strain, P3(T), was isolated from a red snow obtained from Antarctica. Cells of strain P3(T) were rod-shaped, non-motile, catalase-negative, oxidase-positive and Gramstain-negative. Growth was observed at temperatures ranging from 0 to 25 degrees C, with optimum growth at 15 degrees C. The pH range for growth was pH 5.3-7.8. The G+C content of the genomic DNA was 55.0 mol%. The major components in the fatty acid profile were iso-C-15: 0, summed feature 4 (iso-C-17:1 I and/or anteiso-C-17:1 B), anteiso-C-15:0 and summed feature 3 (isoC(16:1)omega 7c and/or iso-C(16:1 omega)6c). The predominant isoprenoid quinone was MK-7. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the novel isolate was a member of the genus Hymenobacter, and the strain showed highest sequence similarity (94 %) with Hymenpbacter glaciei VUG-A130(T), Hymenobacter soli PB17(T) and Hymenobacter antarcticus VUG-A42aa(T). On the basis of phylogenetic and phenotypic properties strain P3(T) represents a novel species of the genus Hymenobacter (for which the name Hymenobacter nivis sp. nov. is proposed. The types strain is P3(T) (= DSM 101755(T) = NBRC 111535(T)).
