Oryzihumus leptocrescens gen. nov., sp. nov.
Three novel strains were isolated from a soil sample collected in Japan using GPM agar plates supplemented with superoxide dismutase and/or catalase. The strains were Gram-positive, catalase-positive, irregular rod-shaped bacteria with meso-diaminopimelic acid as a peptidoglycan diagnostic diamino acid, and the acyl type of the peptidoglycan was acetyl. The major menaquinone was MK-8(H4). Mycolic acids were not detected. The G+C content of the DNA was 72-73 mol%. On the basis of morphological and chemotaxonomic properties and a phylogenetic analysis using 16S rRNA gene sequences, these strains were classified as a novel genus and species, Oryzihumus leptocrescens gen. nov., sp. nov., in the family Intrasporangiaceae of the order Actinomycetales. The type strain is KV-628T (=NRRL B-24347T=JCM 12835T=NBRC 100762T).
