Abstract

A Gram-negative, short rod-shaped, nitrogen-fixing bacterium (CC-21) was isolated from a soil sample collected from the regional agricultural research station in Kaohsiung County (Taiwan). Using 16S rRNA gene sequence analysis, it could be clearly demonstrated that this isolate was novel: it showed <97 % similarity to species of the genera , , , and . The organism used several organic acids, but only a few sugars as substrates. The fatty acid profile differed from those reported for members of the genera , , , and . On the basis of 16S rRNA gene sequence analysis in combination with physiological data, strain CC-21 represents a novel species in a new genus, for which the name gen. nov., sp. nov. is proposed; the type strain is CC-21 (=CCUG 54492=CIP 109510).
