Strain JC141(T) was isolated from an alkaline soil (pH 8.8) at Mau, Uttar Pradesh, India. Colonies were blue with a metallic sheen; cells stained Gram-negative, and were oxidase- and catalase-positive, but chitinase-negative. Major fatty acids were C16:1ω7c/C16:1ω6c, C16:0 and C18:0 with minor amounts of C10:0, C10:0 3-OH, C12:0, C14:0 and C18:1ω7c. Strain JC141(T) contained phosphatidylethanolamine and phosphatidylglycerol as major polar lipids, with minor amounts of diphosphatidylglycerol, unidentified aminolipids (AL1-3) and unidentified lipids (L1-4). A bacterial hopane derivative (BHD1) was the major hopanoid. Genomic DNA G+C content was 62.5 mol%. 16S rRNA gene sequence comparisons indicated that strain JC141(T) represents a member of the genus Vogesella within the family Neisseriaceae of the class Betaproteobacteria. Strain JC141(T) had a 16S rRNA gene sequence similarity of 98% with Vogesella indigofera ATCC 19706(T) and <96.5% with other members of the genus Vogesella. However, strain JC141(T) showed 45.8% relatedness (based on DNA-DNA hybridization) with V. indigofera LMG 6867(T) (=ATCC 19706(T)). Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strain JC141(T) as a representative of a novel species in the genus Vogesella, for which the name Vogesella alkaliphila sp. nov. is proposed. The type strain is JC141(T) (=KCTC 32041(T)=LMG 27066(T)). An emended description of the genus Vogesella is also proposed.
