Hydrogen Production by the Thermophilic Bacterium, Thermotoga neapolitana
Virtually all members of the order Thermotogales have demonstrated the ability to produce hydrogen and some members of this order produce considerably greater quantities than the rest. With one representative of this order, Thermotoga neapolitana, we have consistently obtained accumulations of 25-30% hydrogen with carbon dioxide as the only other prominent byproduct of the batch reaction (12-15...
متن کاملHydrogen Production by the Thermophilic Bacterium Thermotoga neapolitana
As the only fuel that is not chemically bound to carbon, hydrogen has gained interest as an energy carrier to face the current environmental issues of greenhouse gas emissions and to substitute the depleting non-renewable reserves. In the last years, there has been a significant increase in the number of publications about the bacterium Thermotoga neapolitana that is responsible for production ...
متن کاملAn extremely thermostable xylanase from the thermophilic eubacterium Thermotoga.
Endo-1,4-beta-xylanase (EC 3.2.1.8) was isolated from the culture supernatant of Thermotoga sp. strain FjSS3-B.1, an extremely thermophilic anaerobic eubacterium which grows optimally at 80 degrees C. Activity was purified 165-fold by anion-exchange and hydroxyapatite chromatography. The enzyme has an Mr of 31,000 as determined by SDS/PAGE and 35,000 by analytical gel filtration. The optima for...
متن کاملThe glucose transport system of the hyperthermophilic anaerobic bacterium Thermotoga neapolitana
The glucose transport system of the extremely thermophilic anaerobic bacterium Thermotoga neapolitana was studied with the nonmetabolizable glucose analog 2-deoxy-D-glucose (2-DOG). T. neapolitana accumulated 2-DOG against a concentration gradient in an intracellular free sugar pool that was exchangeable with external source of energy, such as pyruvate, and was inhibited by arsenate and gramici...
متن کاملCoregulation of beta-galactoside uptake and hydrolysis by the hyperthermophilic bacterium Thermotoga neapolitana
Regulation of the beta-galactoside transport system in response to growth substrates in the extremely thermophilic anaerobic bacterium Thermotoga neapolitana was studied with the nonmetabolizable analog methyl-beta-D-thiogalactopyranoside (TMG) as the transport substrate. T. neapolitana cells grown on galactose or lactose accumulated TMG against a concentration gradient in an intracellular free...
