| 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)).
