Biohydrogen Production by Anaerobic Biological Fermentation of Agriculture Waste

Efficient conversion of corn stalk wastes into biohydrogen gas by microorganisms was reported for the first time. Batch tests were carried out to analyze influences of several environmental factors on biohydrogen production from corn stalk wastes. The maximum yield of hydrogen 58.6 ml H2/g TVS was observed at 100 h, the value is about 22-fold as compared with that of raw corn stalk wastes. The results indicated that the HCl pretreatment of the substrate plays a key role in the conversion of the corn stalk wastes into biohydrogen.
