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. specialized Thermodesulfovibrio hydrogeniphilus sulphate reducing bacterium hot spring taxonomy 084 020 31 1 38-42 2008 0723-2020 https://www.documentation.ird.fr/hor/fdi:010042582 10.1016/j.syapm.2007.12.002 0723-2020 [F B010042582] https://www.documentation.ird.fr/hor/fdi:010042582 https://www.documentation.ird.fr/intranet/publi/2008/05/010042582.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-05-30 2017-08-23 fdi:010042582 fre
