Water extraction of raw chicken manure elevated the carbon-to-nitrogen ratio 2.7-fold, i.e. from 7.48 to 19.81. The treated chicken manure (T-CM) thus became suitable for biogas fermentation as monosubstrate. Improved methane production was achieved in co-fermentations with either maize silage (24% more methane) or corn stover (19% more methane) relative to T-CM monosubstrate. The standardized biogas potential assay indicated that the methane yields varied with the organic loading rate between 160 and 250 mL CH/g organic total solid (oTS). Co-fermentation with maize silage was sustainable in continuous anaerobic digestion for at least 4 months.
生鸡粪的水提取使碳氮比提高了2.7倍，即从7.48提高到19.81。处理后的鸡粪（T-CM）因此适合作为单一底物进行沼气发酵。与玉米青贮料（甲烷产量提高24%）或玉米秸秆（甲烷产量提高19%）共同发酵相对于T-CM单一底物而言，实现了更高的甲烷产量。标准化沼气潜力测定表明，甲烷产量随有机负荷率在160至250 mL CH/g有机总固体（oTS）之间变化。与玉米青贮料共同发酵在连续厌氧消化中可持续至少4个月。
