Dark fermentation is subject to inhibition by end products. In this study, the effects of acetate, butyrate and lactate on fermentation routes of glucose were investigated for concentrations ranging from 25 to 400 mM. Whatever the acid considered, an inhibition threshold of hydrogen production was o...
