Lentzea terrae sp nov., isolated from soil and an emended description of Lentzea soli

A novel actinobacterium, designated strain NEAU-LZS 42(T), was isolated from soil collected from Mount Song, Henan Province, China, and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the organism should be assigned to the genus Lentzea and had the closest relationship with Lentzea soli NEAU-LZC 7(T) (99.1% similarity) and Lentzea cavernae SYSU K10001(T) (98.2 %). The major menaquinones were identified as MK-9(H4) and MK-9(H2). The phospholipid profile was found to contain diphosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, glycophospholipid and three unidentified lipids. The major fatty acids were iso-C-16:0, C16(:1)omega 7c and C-16:0. DNA-DNA hybridization results and some phenotypic characteristics indicated that strain NEAU-42(T) could be clearly differentiated from L. soil NEAU-LZC 7(T) and L. caverne SYSU K10001(T). Therefore, it is concluded that strain NEAU-LZS 42(T) represents a novel species ofthe genus Lentzea, for which the name Lentzea terrae sp. nov. is proposed. The type stain is NEAU-LZS 42(T) (= CGMCC 4.7428(T) = DSM 105696(T)).
