This present work intends to improve on the possibility of enhancing solubilization and biohydrogen (H2) production from Chaetomorpha antennina (marine macroalgae) through surfactants (ammonium dodecyl sulfate—ADS) aided with microwave disintegration pretreatment (SMD). Microwave disintegration (MD) was implemented by varying power intensity from 10 to 70% for the time period of 0 to 30 min. In microwave disintegration (MD), maximum soluble organic release of 1,260 mg/L and solubilization of 14.6% were achieved within 15 min. Through surfactants, soluble organic release improves up to 1,490 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 the SMD method. SMD pretreatment therefore reduces pretreatment time and increases the organic release compared to MD.
