Fig. 3

Product spectrum (values in the y-axis expressed in mg COD) over time in the different phases (II-A, II-B and II-C) of Experiment II. Experiment II lasted 596 h and values in the x-axis correspond to the different sampling points. Data are presented for mixed substrate treatments at 5 bar pCO2 (GG_CO2) (A), mixed substrate control at 5 bar pN2 (GG_N2) (B) and single substrate controls (glucose GLU_CO2 and glycerol GLY_CO2) (C and D). Abbreviations correspond to methane (CH4), butyrate (Bu), propionate (Pr) and acetate (Ac)
