Research Abstract |
Hydrogen (700 mL/kg-cow dung) was produced by dry fermentation of cow dung at a optimum temperature of 60℃ using hydrogen-producing bacteria, naturally present in the dung. Extremely thermophilic microflora, enriched from cow dung, showed a high hydrogen yield of 3.32 mol/mol-glucose at the HRT of 3 days in continuous culture. The microflora was suggested to posses unusual fermentative properties, as compared with moderately thermophilic and mesophilic bacteria.
