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

A novel actinobacterium, designated strain NEAU-LZS 42, 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 (99.1 % similarity) and Lentzea cavernae SYSU K10001 (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-C16 : 0, C16 : 1ω7c and C16 : 0. DNA-DNA hybridization results and some phenotypic characteristics indicated that strain NEAU-LZS 42 could be clearly differentiated from L. soli NEAU-LZC 7 and L. cavernae SYSU K10001. Therefore, it is concluded that strain NEAU-LZS 42 represents a novel species of the genus Lentzea, for which the name Lentzea terrae sp. nov. is proposed. The type stain is NEAU-LZS 42 (=CGMCC 4.7428=DSM 105696).
