Elbaz Poulichet, F. Hamdi, M. /Ollivier, Bernard Thermodesulfovibrio hydrogeniphilus sulphate reducing bacterium hot spring taxonomy A new thermophilic sulphate-reducing bacterium (strain Hbr5(T)) was enriched and isolated from a terrestrial Tunisian hot spring. It was a non-spore-forming Gram-negative curved or vibrio-shaped bacterium. It appeared singly or in long chains and was actively motile by a polar flagellum. It possessed c-type cytochromes and desulfofuscidin. Growth occurred between 50 and 70 degrees C, with an optimum of 65 degrees C at pH 7.1. In the presence of sulphate as a terminal electron acceptor, this strain readily used H-2 but formate only poorly. It could use sulphate, thiosulphate, sulphite or arsenate as electron acceptors. Its DNA G+C content was 36.1mol%. Based on phenotypic, genomic, and phylogenetic characteristics, strain Hbr5(T) ( = DSM 18151(T), = JCM 13991(T)) is proposed to be assigned to a novel species of genus Thermodesulfovibrio, T. hydrogeniphilus sp. nov. 2008 text https://www.documentation.ird.fr/hor/fdi:010042582 fdi:010042582 Haouari Olfa, Fardeau Marie-Laure, Cayol Jean-Luc, Fauque Guy, Casiot C., Elbaz Poulichet F., Hamdi M., Ollivier Bernard.
