Abstract

Photofermentation of pulp and paper mill effluent (PPME) using Rhodobacter sphaeroides NCIMB8253 was investigated under the supplementation of Fe3+. The concentrations of Fe3+ were varied from 0.1, 0.5, 0.75 and 1.00 mM. The findings from this study showed that an addition of Fe3+ into PPME enhanced the biohydrogen productivity. Modified PPME with an addition of 0.75 mM of Fe3+ produced the highest amount of accumulated biohydrogen of 277.25 mL after 72 h of photofermentation process. However, 1.00 mM of Fe3+ reduced biohydrogen accumulation to 62.8 mL, suggesting that overdosing of iron source was unfavourable for biohydrogen production. In conclusion, the introduction of appropriate concentration of iron ions into PPME enhanced both the biohydrogen productivity and the cell growth.
