Abstract
Biohydrogen production and analysis of microbial community were attempted from the sugar manufacturing wastewater with anaerobic fermentation process. Addtion of nutrients (NㆍP) into sugar manufacturing wastewater stimulates hydrogen production from 9.53 to 26.67㎖ H2/g COD. Butyric acid, acetic acid, lactic acid, and propionic acid were detected in the sample of the anaerobic fermentation process. Butyric acid/Acetic acid(B/A) ratio was increased 0.50 to 0.92 according to the nutrients addtion into the wastewater. Microbial community was analyzed as Clostridium sp. in the phylum of Firmicutes and Klebsiella sp., Erwinia sp., and enterobacter sp. of the class of γ-Proteobacteria. As the improvement of hydrogen production, Erwinia sp. was decreased and Klebsiella sp. was increased.
