Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 4,   Pages 380-386 doi: 10.1007/s11783-009-0142-0

Abstract: The effects of nitrate on fermentative hydrogen production and soluble metabolites from mixed cultureswere investigated by varying nitrate concentrations from 0 to 10g N/L at 35°C with an initialpotential, hydrogen yield, and average hydrogen production rate initially increased with increasing nitrateconcentrations from 0 to 0.1g N/L, while they decreased with increasing nitrate concentrationsA concise model was proposed to describe the effects of nitrate concentration on average hydrogen production
