ABSTRACT=This present work intended to enhance the possibility of enhance the solubilization and biohydrogen (H2) production from Chaetomorpha antennina (marine macroalgae) through surfactant (ammonium dodecyl sulfate – ADS) aided with microwave disintegration pretreatment (SMD). Microwave disintegration (MD) was implemented by varying power intensity from 10 – 70% for the time period of 0 – 30 mins. In microwave disintegration (MD), maximum soluble organic release of 1260 mg/L and solubilization of 14.6 % were attained in 15 mins. Using surfactant, soluble organic release improves up to 1490 mg/L at the optimum MD power condition of 40 %. High solubilization of 17.3% was achieved at dosage of 0.0035 g/g TS. Higher H2 generation of 74.5 mL/g COD was obtained in SMD method. Hence, SMD pretreatment reduced the pretreatment time and increases the organic release compared to MD.
