Figure 1From: Fermentative hydrogen production from glucose and starch using pure strains and artificial co-cultures of Clostridium spp. Comparison of a single-batch fermentation approach (monitoring the biogas flow rate) versus a multi-stage fermentation approach (monitoring the H2yield obtained at different pH values) to evaluate the optimal pH for H2production. (A)-C. butyricum; (B)-C. pasteurianum.Back to article page
