Schumannella luteola gen. nov., sp. nov., a novel genus of the family Microbacteriaceae

Abstract

An actinobacterial strain KHIA^T, isolated from lichen in Tokyo, was taxonomically characterized using a polyphasic approach. The isolate is a Gram-positive, anaerobic, non-motile and rodshaped bacterium. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the isolate is represented as an independent lineage distinctive from the Microbacteriaceae genera. The G + C content of DNA was 58.7 mol%. The chemotaxonomic characteristics of the isolate are cell wall peptidoglycan type (2,4-diaminobutyric acid), major cellular fatty acids (anteiso-C_15:0 and iso-C_16:0) and quinone type (MK-11 and MK-10). On the basis of the phenotypic and phylogenetic distinctness, it is proposed that strain KHIA^T represents a novel species in a new genus of the family Microbacteriaceae, Schumannella luteola gen. nov., sp. nov. The type strain is KHIA^T (=JCM 23215^T=TISTR 1824^T).
