Abstract

A novel methane-oxidizing bacterium, strain HTM55, was isolated from subsurface hot aquifer water from a Japanese gold mine. Strain HTM55 was a Gram-negative, aerobic, motile, coccoid bacterium with a single polar flagellum and the distinctive intracytoplasmic membrane arrangement of a type I methanotroph. Strain HTM55 was a moderately thermophilic, obligate methanotroph that grew on methane and methanol at 37–65 °C (optimum 55–60 °C). The isolate grew at pH 5.2–7.5 (optimum 5.8–6.3) and with 0–1 % NaCl (optimum 0–0.3 %). The ribulose monophosphate pathway was operative for carbon assimilation. The DNA G+C content was 54.4 mol% and the major fatty acids were C (52.0 %) and Cω7 (34.8 %). Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain HTM55 was closely related to MYHT (99.2 % 16S rRNA gene sequence similarity), which is within the class . However, DNA–DNA relatedness between strain HTM55 and MYHT was ≤39 %. On the basis of distinct phylogenetic, chemotaxonomic and physiological characteristics, strain HTM55 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HTM55 ( = JCM 13664 = DSM 19750).
