Interspecies Transport of Hydrogen in Thermophilic Anaerobic Cellulose Decomposition
Hydrogen is the key metabolite in the process of anaerobic decomposition of complex organic compounds and plays the regulatory role in the methanogenic comunity. A considerable amount of hydrogen, which is consumed by methanogenic and homoacetogenic bacteria, is formed in the process of cellulose fermentation by anaerobic cellulolytic bacteria. The effect of interspecies hydrogen transfer on cellulose decomposition by combined cultures of Clostridium thermocellum with hydrogen utilizing methanogenic bacterium Methanobacterium thermoformicicum and homoacetogenic bacterium Clostridium thermoautotrophicum was stadied.
