Table 1.
Chemical characterization of substrates used in the co-digestion experiments.
Figure 1.
Daily biogas production from the co-digestion of GM and WS (A), CS (B) and RS (C) with different mixing ratios.
Mean values originated from three independent replications. Vertical bars represent standard deviations.
Figure 2.
Cumulative biogas productions from co-digestion of GM and WS (A), CS (B) and RS (C) with different mixing ratios.
Mean values originated from three independent replications. Vertical bars represent standard deviations.
Figure 3.
Total biogas productions from anaerobic co-digestion of GM with WS, CS and RS with different mixing ratios.
Mean values originated from three independent replications. Vertical bars represent standard deviations. The ANOVA test was conducted to determine the differences between each cultivar. Values with the same letters indicate no significant difference at P<0.01.
Table 2.
Mean values for C/N ratios in the co-digestion of GM with three CRs.
Figure 4.
VFA concentrations and pH values from the co-digestion of GM and WS (A), CS (B) and RS (C) with different mixing ratios.
Mean values originated from three independent replications. Columns represent VFA, lines represent pH values, and vertical bars represent standard deviations. VFA, volatile fatty acid.
