Abstract

In this study, the taxonomic positions of 19 isolates disclosed in a previous study were evaluated. Phylogenetic analysis based on 16S rDNA sequences partitioned these isolates into groups that were closely related (98·8–99·1 % similarity) to and , respectively. DNA–DNA hybridization experiments further showed that these groups had <70 % similarity to other species. Two novel species are proposed to accommodate these groups: sp. nov. (type strain, LMG 21557=CAIM 629) and sp. nov. (type strain, LMG 20362=CAIM 693). The DNA G+C content of both novel species is 45·6 mol%. Useful phenotypic features for discriminating and from other species include production of indole and acetoin, utilization of cellobiose, fermentation of amygdalin, melibiose and mannitol, -galactosidase and tryptophan deaminase activities and fatty acid composition.
