Xin-Jiang, China, was subjected to polyphasic taxonomic characterization. This strain, designated AB14T, is neutrophilic, motile and requires at least 10 % (w/v) NaCl for growth. Strain AB14T grows at 24–58 6C, with optimal growth at 42–45 6C. Mg2+ is not required, but growth is observed in MgCl2 concentrations as high as 1?0 M. Strain AB14T possesses the diphytanyl (C20C20) and phytanyl-sesterterpanyl diether (C20C25) derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and mannose-2,6 disulfate 1R2 glucose-glycerol diether. The genomic DNA G+C content is 66?6 mol%. The 16S rRNA gene sequence similarity values of strain AB14T with its nearest phylogenetic neighbours (Haloterrigena thermotolerans and Haloterrigena turkmenica) are 98?6 and 96?0%, respectively. DNA–DNA hybridization revealed 54 % relatedness between strain AB14T and Haloterrigena thermotolerans JCM 11050T and 21 % between strain AB14T and Haloterrigena turkmenica JCM 9101T. It is therefore proposed that strain AB14T represents a novel species, for which the name Haloterrigena saccharevitans sp. nov. is proposed. The type strain is AB14T (=AS 1.3730T=JCM 12889T). The genus Haloterrigena currently contains two species o
