ABSTRACT=<p>This present work intends to improve on the possibility of enhancing solubilization and biohydrogen (H<sub>2</sub>) production from <italic>Chaetomorpha antennina</italic> (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 H<sub>2</sub> 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.</p>
