abstract= A novel halophilic actinomycete, designated strain J11Y309T, was isolated from a soil sample collected from a dried salt lake in China. This isolate grew optimally at 28‒37 °C, with 3‒5 % (w/v) NaCl and at pH 7.0‒7.5. It contained meso-diaminopimelic acid as the diagnostic diamino acid and glucose, ribose and xylose were present in the whole-cell hydrolysates. MK-10(H4) was detected as the predominant menaquinone. The major fatty acids were anteiso-C17 : 0, iso-C16 : 0, iso-C17 : 0 and iso-C15 : 0. Polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, phosphoglycolipids, glycolipids, an unidentified phospholipid and additional unidentified lipids. The G+C content of the genomic DNA was 63.0 mol%. The novel strain shared highest 16S rRNA gene sequence similarity with Salininema proteolyticum Miq-4T (95.80 %), Paraglycomyces xinjiangensis TRM 49201T (95.77 %) and Haloglycomyces albus YIM 92370T (94.84 %). Phylogenetic trees showed that it could not be clearly assigned to any known genus within the family Glycomycetaceae and formed a distinct phylogenetic line in the clade comprising members of the genera Salininema , Paraglycomyces and Haloglycomyces . Based on data from the present polyphasic taxonomic study, strain J11Y309T represents a novel species of a new genus in the family Glycomycetaceae , for which the name Salilacibacter albus gen. nov., sp. nov. is proposed with Salilacibacter albus sp. nov. as the type species. The type strain of Salilacibacter albus is J11Y309T (=DSM 46875T=CGMCC 4.7242T=LMG 29297T). Reclassification of Paraglycomyces xinjiangensis Luo et al. 2015 as a later heterotypic synonym of Salininema roteolyticum Nikou et al. 2015 is also discussed in this study.,
