Abstract

•Enriched hydrogenotrophic methanogens in the inoculum accounted for the raised CH4.•The highest methane yield was 411 mL/g-VS with the substrate degradation of 91.2%.•The optimal carbohydrate/protein/cellulose ratio for CH4 generation was 50:45:5.•Modified Gompertz model can predict the biomethanation of carbohydrate-rich waste.•Anaerobic granular sludge inoculum was fit for carbohydrate-rich waste digestion.
