Belliella pelovolcani sp. nov., isolated from a mud-volcano in Taiwan

Strain CC-SAL-25(T), a non-motile, Gram-negative, red-pigmented bacterium, was isolated from a rare mud-volcano, located in Wandan, Pingtung County, Taiwan. Studies based on 16S rRNA gene sequences showed that the strain clustered closely with Belliella baltica BA143(T) (95.4 % sequence similarity). A menaquinone with seven isoprene units (MK-7) was the major respiratory quinone. The fatty acid profile was slightly different from that of B. baltica BA143(T). The results of the physiological and biochemical tests showed that strain CC-SAL-25(T) could be clearly differentiated from recognized Belliella species based on phenotypic properties. It was evident from the genotypic and phenotypic data that strain CC-SAL-25(T) should be classified as representing a second novel species in the genus Belliella. The name proposed for this taxon is Belliella pelovolcani sp. nov., and the type strain is CC-SAL-25(T) (=BCRC 17883(T)=KCTC 13248(T)).
