By combining surfactant with disperser, Biohydrogen the speciﬁc energy input was considerably reduced from 437.1 kJ/kg TS to 264.9 kJ/kg TS to achieve 10.7% Fermentation liquefaction. A disperser rpm (10,000), pretreatment time (30 min) and tween 80 dosage (21.6 mg/L) were Speciﬁc energy considered as an optimum for eﬀective liquefaction of algal biomass. CMP was designated as an appropriate Algal biomass
