Metabolite production in cultures with the anaerobic enrichment inocula. CH4 (A), CO2 (B) and the main fermentation products acetate (C) and propionate (D) where closed circles = Chlorella vulgaris and U-C, closed squares = C. vulgaris and B-C, closed triangles = Dunaliella tertiolecta and U-D, and crosses = D. tertiolecta and B-D. H2-fermenting cultures (with 20 mM BESA): C. vulgaris biomass as substrate = B-C; D. tertiolecta biomass as substrate = B-D; CH4-producing cultures: C. vulgaris biomass as substrate = U-C; D. tertiolecta biomass as substrate = U-D.
