Bacterium Strain

An anaerobic, thermophilic bacterium, strain SET IS-9T, was isolated from an Icelandic hot spring. Cells of strain SET IS-9T are short, slightly curved, motile rods. The strain grows chemolithotrophically on CO, producing equimolar quantities of H2 and CO2. It also grows fermentatively on lactate or pyruvate in the presence of yeast extract (0.2 g l−1). Products of pyruvate fermentation are acetate, CO2 and H2. Growth occurs at 50–70 °C, with an optimum at 65 °C, and at pH 5.0–8.0, with an optimum at pH 5.5–6.0. The generation time during chemolithotrophic growth on CO under optimal conditions is 2.0 h. 16S rRNA gene sequence analysis suggested that the organism belongs to the genus Carboxydothermus. On the basis of phenotypic features and phylogenetic analysis, Carboxydothermus islandicus sp. nov. is proposed, with the type strain SET IS-9T ( = DSM 21830T  = VKM B-2561T). An emended description of the genus Carboxydothermus is also given.

Bacterium Strain

A novel chemolithotrophic bacterium, strain 16CT, was isolated from a hot spring in Graendalur, south-west Iceland. Cells of this organism were Gram-negative, rod-shaped and motile. The isolate was aerobic and capable of chemolithotrophic growth on hydrogen and carbon dioxide, heterotrophic growth on butyrate and several other organic compounds, and mixotrophic growth on butyrate, hydrogen and carbon dioxide. Heterotrophic growth was generally enhanced in the presence of yeast extract. Autotrophic growth on hydrogen was observed at pH values between 6.0 and 10.0 and temperatures between 35 and 60 °C; optimum growth conditions were pH 7.0 and 55 °C. The DNA G+C content was 63.9 mol%. 16S rRNA gene sequence analysis showed that strain 16CT was a member of a distinct species belonging to the class Betaproteobacteria and was most closely related to Hydrogenophilus thermoluteolus NBRC 14978T and Hydrogenophilus hirschii DSM 11420T. The major cellular fatty acids were straight-chain C16 : 0 (44.98 %) and C18 : 1 ω7c (17.93 %), as well as cyclic C17 : 0 (13.90 %) and C19 : 0 ω8c (4.67 %) fatty acids. Based on its physiological and molecular properties, it is concluded that strain 16CT represents a novel species within the genus Hydrogenophilus, for which the name Hydrogenophilus islandicus is proposed; the type strain is 16CT (=DSM 21442T=JCM 16106T).
