Stackebrandtia nassauensis gen. nov., sp. nov. and emended description of the family Glycomycetaceae.
During the course of a 16S rRNA gene sequence phylogenetic evaluation of putative Glycomyces strains, it was noted that strain NRRL B-16338(T) is phylogenetically nearest to the genus Glycomyces but apparently is not a member of this or any of the other currently described actinomycete genera. The strain was subjected to a polyphasic study using standard methods for chemotaxonomic, morphological and physiological evaluation. The strain exhibited chemotaxonomic characteristics distinct from Glycomyces in spite of having 16S rRNA gene sequence similarity of 92% with the described species of this genus. The whole-cell sugar pattern of NRRL B-16338(T) consisted of ribose and inositol, with traces of arabinose and mannose. The phospholipids observed were phosphatidylglycerol and diphosphatidylglycerol and menaquinones consisting of MK-10(H(4)), MK-10(H(6)), MK-11(H(4)) and MK-11(H(6)). A significant quantity (14.5%) of 17:0 anteiso 2-hydroxy fatty acid was observed in the fatty acid profile of this strain. These characteristics clearly differentiate NRRL B-16338(T) from members of the genus Glycomyces and it is proposed that the strain represents a new genus within the family Glycomycetaceae to be called Stackebrandtia gen. nov. The description of this family is emended to permit its inclusion. It is proposed that the type species of the genus should be named Stackebrandtia nassauensis. The type strain LLR-40K-21(T) (=NRRL B-16338(T)=DSM 44728(T)) was isolated from a soil sample from Nassau, Bahamas.
