Verrucosispora wenchangensis sp. nov., isolated from mangrove soil
An actinomycete strain 234402T was isolated from a mangrove soil sample collected in Wenchang, China. Phylogenetic analysis of the 16S rRNA gene sequence of strain 234402T indicated that the highest similarity was to Verrucosispora sediminis MS426T (99.25%). The cell wall contained meso-diaminopimelic acid. The major menaquinones were MK-9(H4) and MK-9(H6), with MK-9(H8) as minor components. The characteristic whole-cell sugars were xylose, mannose and glucose. The phospholipid profile was found to comprise phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside and an unknown phospholipid. The DNA G+C content was 69.2 mol%. The results of physiological and biochemical tests and low DNA–DNA relatedness demonstrated strain 234402T could be readily distinguished from the closely related Verrucosispora species. On the basis of these phenotypic and genotypic data, strain 234402T represents a novel species of the genus Verrucosispora, for which the name Verrucosispora wenchangensis sp. nov. is proposed. The type strain is 234402T (=CCTCC AA 2011018T=DSM 45674T).
