Comparison of thermophilic bacteria and alkyl polyglucose pretreatment on two-stage anaerobic digestion with waste sludge: Biogas production potential and substrate metabolism process

[Display omitted] •APG pretreated waste sludge was positive for hydrogen production.•TB pretreated waste sludge was advantageous for methane production.•Aromatic proteins and soluble microbial materials were well utilized with TB sludge.•Biodegradable substances used little with APG sludge during me...
