Archaeal community dynamics and abiotic characteristics in a mesophilic anaerobic co-digestion process treating fruit and vegetable processing waste sludge with chopped fresh artichoke waste

► Co-digestion of fruit and vegetable waste sludge with artichoke waste enhanced biogas production. ► Methanosaeta and Methanosarcina dominanted the methanogenic community. ► Methanosarcina numbers increased upon co-digestion with chopped fresh artichoke waste. ► Methanosaeta numbers decreased upon co-digestion with chopped fresh artichoke waste.
