Strain KV-657(T) was isolated from a paddy field soil sample collected in Japan using GPM agar plates supplemented with catalase. The strain was a Gram-positive, aerobic organism that formed branching hyphae with ll-diaminopimelic acid as the diagnostic peptidoglycan diamino acid. The major menaquinone was MK-8(H(4)). Mycolic acids were not detected. The G+C content of the DNA was 70 mol%. 16S rRNA gene sequence analysis revealed that this strain is closely related to Intrasporangium calvum DSM 43043(T), with a similarity of 97.6 %. Based on the morphological, biochemical and chemotaxonomic properties of this strain and phylogenetic analysis, it was concluded that this isolate represents a new genus and species in the family Intrasporangiaceae, for which the name Humihabitans oryzae gen. nov., sp. nov. is proposed. The type strain of Humihabitans oryzae is KV-657(T) (=NRRL B-24470(T) =NBRC 101802(T)).
