Abstract

A novel bacterium, strain B33D1, isolated from agricultural soil, was characterized taxonomically and phylogenetically. Strain B33D1 was a Gram-positive, aerobic rod of medium length that formed long chains on a common laboratory medium. However, B33D1 grew poorly on the surface of agar plates and was sensitive to desiccation. The optimal growth temperature was 30 °C (range 19–38 °C). The organism grew well on a variety of sugars and was capable of utilizing a few amino acids as sole carbon sources. Phylogenetically, the most closely related described species to strain B33D1 was , which possessed 86 % 16S rRNA sequence similarity. However, a number of 16S rRNA gene clones derived from soil samples possessed up to 93 % sequence similarity. These results placed strain B33D1 within the subclass of the phylum . The novel genus and species gen. nov., sp. nov. is proposed, with strain B33D1 (=ATCC BAA-492=DSM 14954) as the type strain.
