Abstract
In this study, variations of hydrogen production were investigated with food waste fermentation in the presence of heavy metals. Hydrogen production was 79.48 mL/g COD with fermentation of food waste. In the presence of 1 mg/L of zinc, the hydrogen production was decreased about 60%. When the copper is present, the production of hydrogen is severely inhibited, while the coexistence of copper with zinc relaxes the inhibition of copper and restores hydrogen production. Butyric acid or acetic acid was observed as the main species during hydrogen production. Klebsiella sp., Clostridium sp., and Dysgonomonas sp. were mainly appeared in the samples not containing heavy metals. However, Enterococcus sp. extremely influenced the hydrogen production activities of samples containing zinc or copper.
