Abstract

Five strains of bacteria isolated from nodules of and in Yunnan Province of China were classified within the genus in the class . The highest degree of 16S rRNA gene sequence similarity was determined to be to LMG 6125 (99.7 %) and UPM-Ca7 (99.7 %). Polyphasic taxonomic methods including SDS-PAGE of whole-cell soluble proteins, comparative housekeeping sequence analysis of , and , fatty acid profiles and a series of phenotypic and physiological tests allowed us to cluster the five strains into a coherent group while differentiating them from all previously established species. The DNA–DNA relatedness between the representative strain CCBAU 65327 and the type strains of and was 26.5 and 23.4 %, respectively, clearly indicating that strain CCBAU 65327 represents a novel species for which we propose the name sp. nov. Strain CCBAU 65327 (=LMG 24762 =HAMBI 3050) is designated as the type strain, and could nodulate , , , , and in cross-nodulation tests.
