This study examines the effects of linear alkylbenzene sulfonate on hydrogen fermentation of food
waste. The hydrogen production rate was similar with different linear alkylbenzen sulfonate (LAS) concentrations.
The maximum hydrogen yield increased with increasing LAS concentration. The highest maximum hydrogen yield
was 0.550 ± 0.005 mol H2/mol hexose at LAS for 5.52 mg/L. But the maximum hydrogen yield decreased above
LAS for 11.05 mg/L. The concentration of acetate in control reactor was increased, but it decreased with increasing
LAS concentration in other reactors.
