Abstract
The disclosure provides a method for biohydrogen production. The method includes: mixing a hydrogen production medium and a buffer solution Na2HPO4/NaH2PO4 having a pH value of 5-9, to yield a first mixture; adding corn stalk powder and cellulase to the first mixture and mixing, to yield a second mixture; adding a suspension of photosynthesis bacteria HAU-M1 at the late exponential phase to the second mixture, to yield a third mixture; and sealing the third mixture and allowing for photo-fermentation biohydrogen production under anaerobic fermentation conditions.
