Verrucosispora lutea sp. nov., isolated from a mangrove sediment sample

A novel Gram-positive, aerobic, spore-forming actinobacterium, designated strain YIM 013T, was isolated from a mangrove sediment sample and subjected to a polyphasic taxonomic study. The peptidoglycan type was A1gamma and the major whole-cell sugars contained glucose and xylose. The phospholipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and some unknown phospholipids. The predominant menaquinone was MK-9(H4). The major fatty acids were iso-C15:0 and iso-C16:0. The genomic DNA G+C content was 69.3 mol%. blast search results based on an almost-complete 16S rRNA gene sequence showed that strain YIM 013T had the highest similarity with Verrucosispora gifhornensis DSM 44337T (98%) and phylogenetic analysis revealed that strain YIM 013T should be assigned to the genus Verrucosispora. The mean level of DNA-DNA relatedness between strain YIM 013T and V. gifhornensis DSM 44337T was 38.2%. Based on its phenotypic and genotypic characteristics, strain YIM 013T (=CCTCC AA207012T=KCTC 19195T) is proposed to be the type strain of a novel species, Verrucosispora lutea sp. nov.
