Haloglycomyces albus gen. nov., sp. nov., a halophilic, filamentous actinomycete of the family Glycomycetaceae.
A novel halophilic actinobacterium, designated YIM 92370(T), was isolated from a hypersaline habitat in Xinjiang Province, north-west China. The strain was aerobic, Gram-positive-staining and halophilic, with an optimum NaCl concentration for growth of 8-12 % (w/v). The whole-cell sugar pattern consisted of ribose, xylose and glucose. The predominant menaquinone was MK-9(H(4)) and the major fatty acids were iso-C(16 : 0), iso-C(17 : 0) and anteiso-C(17 : 0). The phospholipid pattern consisted of phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides, two unknown phosphoglycolipids and one unknown phospholipid. The G+C content of the genomic DNA was 60.8 mol%. Phylogenetic analysis showed that strain YIM 92370(T) can be distinguished from representatives of Glycomyces and Stackebrandtia, the two existing genera in the family Glycomycetaceae, by low 16S rRNA gene sequence similarities (<93.7 %). Strain YIM 92370(T) therefore represents a novel genus and species of the family Glycomycetaceae, for which the name Haloglycomyces albus gen. nov., sp. nov. is proposed. The type strain of Haloglycomyces albus is YIM 92370(T) (=DSM 45210(T) =KCTC 19481(T)).
