From: Biogenic hydrogen and methane production from Chlorella vulgaris and Dunaliella tertiolectabiomass
Metabolite production in the cultures without anaerobic enrichments. H2 (A), CO2 (B) and the main fermentation products acetate (C) and formate (D) where closed circles = Chlorella vulgaris and no inoculum, closed squares = C. vulgaris, 2-bromoethanesulfonic acid (BESA) and no inoculum, closed triangles = Dunaliella tertiolecta and no inoculum, and crosses = D. tertiolecta, BESA and no inoculum.
