中文摘要	A novel Gram-stain-positive, non-motile, moderately halophilic and alkalitolerant actinobacterium, designated EGI 80432(T), was isolated from a saline-alkaline soil of Xinjiang province, north-west China. Cells were non-endospore-forming cocci with a diameter of 0.5-0.8 mu m. Strain EGI 80432(T) grew in the presence of 0-9 % (w/v) NaCl (optimum at 3-5 %), and also grew within the pH range 6.0-10.0 (optimum at pH 8.0-9.0) on marine 2216E medium. The peptidoglycan type was A1 gamma. The whole-cell hydrolysates contained glucose, galactose, mannose and three unknown sugars as major sugars. The predominant menaquinone was MK-9(H-4). The major fatty acids were C-17 : 1 omega 8c, summed feature 3 (C-16 : 1 omega 7c/C-16 : 1 omega 6c), C-18 : 1 omega 9c and iso-C-15 : 0 The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, one unknown phosphoglycolipid, three unknown phospholipids and four unknown polar lipids. The genomic DNA G + C content was 75.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain EGI 80432(T) clustered within the radius of the class Nitriliruptoria. Levels of sequence similarity between strain EGI 80432(T) and its phylogenetic neighbours Nitriliruptor alkaliphilus ANL-iso2(T) and Euzebya tangerina F10(T) were 94.1 and 88.1 %, respectively. Based on morphological, physiological and chemotaxonomic characteristics and phylogenetic analysis, a novel species of a new genus, Egicoccus halophilus gen. nov., sp. nov., is proposed, within the new family and new order Egicoccaceae fam. nov. and Egicoccales ord. nov. in the class Nitriliruptoria. The type strain of Egicoccus halophilus is EGI 80432(T) (=CGMCC 1.14988(T)=KCTC 33612(T)).
