Abstract

A polyphasic taxonomic study was performed on isolates classified as Centers for Disease Control Group Eugonic Fermenter (EF)-4a and EF-4b. Comparative 16S rRNA gene sequence analysis confirmed that group EF-4a and EF-4b belong to the genus with and as the nearest phylogenetic neighbours. DNA–DNA hybridizations and biochemical analyses demonstrated that isolates of group EF-4a and EF-4b represent two novel species within this sublineage of the genus . Based on the results of the present study, isolates of group EF-4a and EF-4b are classified as sp. nov. (type strain LMG 23011=NCTC 12228) and sp. nov. (type strain LMG 23012=NCTC 12230), respectively.
