Williamsia faeni sp. nov., an actinomycete isolated from a hay meadow.

The taxonomic status of an actinomycete isolated from soil collected from a hay meadow was determined using a polyphasic approach. The strain, designated N1350(T), had morphological and chemotaxonomic properties consistent with its classification in the genus Williamsia and formed a distinct phyletic line within the clade comprising the type strains of species of the genus Williamsia in the 16S rRNA gene tree. Strain N1350(T) shared highest 16S rRNA gene sequence similarities with Williamsia marianensis MT8(T) (98.1 %) and Williamsia muralis MA140-96(T) (98.3 %). However, strain N1350(T) was readily distinguished from the type strains of Williamsia species using a combination of phenotypic properties. On the basis of these data, strain N1350(T) is considered to represent a novel species of the genus Williamsia. The name proposed for this taxon is Williamsia faeni sp. nov., with the type strain N1350(T) (=DSM 45372(T) =NCIMB 14575(T) =NRRL B-24794(T)).
