Abstract

Strain JW/WZ-YB58, a thermophilic (42–64 °C), aerobic, alkalitolerant (pH 6.4–9.7), heterotrophic, sporulating, retarded-peritrichously flagellated and slightly curved rod-shaped bacterium, was isolated from the hot spring Zarvarzin II in the East Thermal Field of the Uzon Caldera, Kamchatka (Far East Russia). The isolate tolerated high concentrations of CO. The major membrane phospholipid fatty acids of JW/WZ-YB58 included iso-C (24.5 %), anteiso-C (18.3 %) and iso-C (17.5 %). The G+C content of the genomic DNA is 45 mol% (HPLC method). Based on 16S rRNA gene sequence analysis and physiological properties, isolate JW/WZ-YB58 (=ATCC BAA-1258 =DSM 17740) is proposed as the type strain of sp. nov. In contrast to the type species , a catalase-reaction-positive aerobe, was catalase-reaction-negative; thus the description of the genus is emended to include a catalase-reaction-negative species.
