چکیده انگلیسی
To improve volatile fatty acids (VFAs) production from spent mushroom compost (SMC), the effect of total solid (TS) content was studied. The protein and polysaccharide solubilization, ammonium (NH4+-N) and phosphate (PO43â-P) release, and VFAs production were analyzed. Results showed that the optimal fermentation time was 4 day for VFAs production, longer fermentation time led to VFAs consumption and methane production. Within the TS range from 6% to 18%, a TS of 15% was the optimal for VFAs production, the highest VFAs concentration reached 2781Â mg/L, and acetate and propionate acids accounted for about 71% of total VFAs. In addition, the maximum concentration of soluble protein and polysaccharide reached approximately 1648Â mg/L and 1394Â mg/L, respectively. The NH4+-N and PO43â-P release was in a range of 2.11-7.59Â mg/gVS and 0.26-1.13Â mg/gVS, respectively. If the NH4+-N and PO43â-P can be removed, the application of VFAs utilization might be significantly enhanced.
