Method of fermentative hydrogen production from the pretreated Tofu-processing Waste

摘要

PURPOSE: A method for generating hydrogen by anaerobic fermentation of bean curd waste is provided to enhance solubilization rate and to effectively produce hydrogen. CONSTITUTION: A method for generating hydrogen by anaerobic fermentation of bean curd waste comprises: a step of adding 0.5-5% (W/W) of HCl to the bean curd waste as pretreatment; a step of adding 5-20%(V/V) of sewage; and a step of inoculating anaerobic microbes adapted to hydrogen production and fermenting at 50-65°C and a pH of 5-6. The microbes are Thermobacterium thermosaccharolyticum, Clostridium thermosaccharolyticum, Clostridium thermoamylolyticum, Sulfobacillus, or Bacillus.
