Thermotoga naphthophila RKU-10

Names Thermotoga naphthophila RKU-10
Accession numbers NC_013642
Background Thermotoga naphthophila (strain ATCC BAA-489 / DSM 13996 / JCM 10882 / RKU-10) is an obligately anaerobic, hyperthermophilic and fermentative heterotrophic Gram-negative bacterium isolated from a deep subterranean oil reservoir in Niigata, Japan. It is rod-shaped with a `toga', a sheathlike structure with ballooning at both ends, which is characteristic of members of the order Thermotogales. T. naphthophila possesses the cellobiose transporter operon, but grows very poorly on cellulose. While it reduces elemental sulfur to hydrogen sulfide, its final cell yield and specific growth rate decrease in the presence of elemental sulfur. The temperature ranges for growth are 48-86 degrees Celsius with an optimum at 80 degrees Celsius. No growth is apparent at 47 or 87 degrees Celsius. The pH ranges for growth 5.4-9.0, with the optimum at pH 7. No growth is apparent at pH 5.2 or 9.5. (Adaptated from PMID: 11594624). (EBI Integr8)
