Abstract

A Gram-negative, rod-shaped, non-spore-forming bacterium, designated strain R2A36-4, was isolated from greenhouse soil and subjected to a polyphasic taxonomic analysis. 16S rRNA gene sequence analysis revealed that the strain represented a novel member of the family . Its nearest phylogenetic neighbour was the type strain of [] CIP 104802 (93.2 % 16S rRNA gene sequence similarity). Strain R2A36-4 and [] CIP 104802 fell in a distinct cluster within the family . Strain R2A36-4 contained MK-7 as the predominant quinone. Strain R2A36-4 and [] CIP 104802 had iso-C, iso-C 3-OH, summed feature 3 and C 6 as the major fatty acids. Strain R2A36-4 could be distinguished from [] on the basis of several physiological properties and fatty acid compositions. Based on phenotypic characterization and 16S rRNA gene sequence analysis, strain R2A36-4 represents a novel species within a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain of is strain R2A36-4 (=KACC 12953=DSM 21342). It is also proposed that [] be transferred to this genus as comb. nov. (type strain UASM 9D=ATCC 29591=CIP 104802=DSM 3403=NBRC 15130=JCM 21819=KACC 13276=LMG 8368).
