Abstract
- The objective of this experimental study was to demonstrate the impact of trace metal supplementation, namely nickel (Ni), cobalt (Co) and molybdenum (Mo), on the methane yields obtained from batch mesophilic anaerobic digestion of maize silage as mono-substrate. The maize silage used in this experimental work initially lacked Ni and Co. Trace metal concentration selected was 0.1 and 0.5 mg/L for Ni and Co, respectively, while it was 0.05 and 0.25 mg/L for Mo. The supplementation by Ni, Co and Mo, individually or in combination at different doses, seemed to improve the methane yields for mono-digestion of maize silage and particularly, the highest methane yield of 0.429 L CH4/g VSaddedwas obtained, when Ni, Co and Mo were supplemented together at concentrations of 0.5, 0.5 and 0.25 mg/L, respectively.
