Abstract
In this study, variations of fermentative hydrogen production and microbial community were investigated with differentnitrogen concentration of food waste. Optimum hydrogen production rate was acquired at 200 mg/L nitrogen concentration of thefood waste. Which was eqivalent to 83.43 mL/g dry biomass/hr. However, bio-hydrogen production was inhibitedly reduced at over600 mg/L of nitrogen concentration whereas proportional relation between hydrogen production and B/A ratio were not observed.
Most dominant specie of the microbial community analyzed was Clostridium sp. throughout PCR-DGGE analysis of 16S rDNA.
It revealed that most contributing microorganism producing hydrogen were Enterococcus faecium partial, Klebsiella pneumoniaestrain ND6, Enterobacter sp. NCCP-231, and Clostridium algidicarnis strain E107 in this experiment.
