Abstract
A novel actinomycete, designated YIM 45751T, was isolated from a soil sample collected from the Xishuang Banna tropical rainforest, Yunnan province, south-west China, and was subjected to a polyphasic taxonomic study. The cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. Whole-cell hydrolysates contained ribose, xylose and glucose. The predominant menaquinones were MK-10(H4), MK-10(H6), MK-11(H4) and MK-11(H6). The polar lipids were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and three unknown phospholipids. 16S rRNA gene sequence analysis showed that Stackebrandtia nassauensis DSM 44728T was the closest phylogenetic neighbour (95.8 % 16S rRNA gene sequence similarity). On the basis of phylogenetic and some common chemotaxonomic data, the isolate should belong to the genus Stackebrandtia. However, phylogenetic analysis and comparison of physiological and chemotaxonomic characteristics demonstrated that the isolate is distinct from S. nassauensis DSM 44728T. Strain YIM 45751T represents a separate species of the genus Stackebrandtia, for which the name Stackebrandtia albiflava sp. nov. is proposed. The type strain is YIM 45751T (=DSM 45044T=CCTCC AA 206003T). Furthermore, the description of the genus Stackebrandtia is also required to be emended.
