Abstract

A Gram-negative, aerobic, heterotrophic bacterium, designated KP1-19, was isolated from a 22-year-old volcanic deposit at a site lacking vegetation on the island of Miyake, Japan. Strain KP1-19 was able to use thiosulfate (optimum concentration 10 mM) as an additional energy source. 16S rRNA gene sequence analysis indicated that strain KP1-19 was closely related to CS-K2 within the class (97.7 % 16S rRNA gene sequence similarity). The cellular fatty acid profile was characteristic of the genus : the major fatty acids (>5 %) were C, C 7 and C 7 and minor amounts of C 3-OH were also found. DNA–DNA relatedness between strain KP1-19 and LMG 19593 was 18 %. Therefore, strain KP1-19 represents a novel species, for which the name sp. nov. is proposed. The type strain is KP1-19 (=LMG 24869 =NBRC 105857 =CIP 109929).
