Biohydrogen production

1
Bio-hydrogen production by anaerobic biological
fermentation of Agriculture waste
2
Our research interest is to convert the biomass
containing cellulose, such as Corn stalk wastes
into hydrogen gas by natural anaerobic
microorganism. For this purpose, several
environmental factors, such as pretreatment of
substrate, initial pH and substrate
concentration, were selected as target factors in
conversion of Corn stalk wastes into biohydrogen
gas by cow dung composts.

• Conclusion
• 1- The HCl pretreatment of the substrate plays a
  key role in conversion of the Corn stalk wastes
  into biohydrogen gas by the cow dung composts.
• 2-The maximum hydrogen yield of 58.6 ml H2/g TVS
  was observed at the fixed initial pH of 7.0 and
  substrate concentration of 25 g/l, the value was
  about 22-fold higher than that of raw Corn stalk
  wastes.
