Skermanella aerolata sp nov., isolated from air, and emended description of the genus Skermanella

A light-pink-coloured bacterium, designated strain 5416(T)-32(T), was isolated from an air sample in Korea. Cells of the strain were strictly aerobic, Gram-negative, motile (single polar or subpolar flagellum) and rod-shaped. Optimal growth occurred at 25-30 degrees C and at pH 6.0-7.0. The major quinones were Q-10 and Q-8. The major fatty acids were C-18:1 omega 7c (53.8%) and C-16:0 (15.9%). The G + C content of the genomic DNA was 65.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 5416(T)-32(T) was most closely related to Skermanella parooensis, with a similarity of 96.2%, but relatively low sequence similarities (< 92%) were found with respect to other species with validly published names held in GenBank. Phenotypic and genotypic analyses indicated that strain 5416(T)-32(T) could not be assigned to any recognized species. Therefore strain 5416(T)-32(T) represents a novel species of the genus Skermanella, for which the name Skermanella aerolata sp. nov. is proposed. The type strain is 5416(T)-32(T) (= KACC 11604(T) =DSM 18479(T)).
