Abstract
High organic content of sago wastewater (SWW) can be utilized as a substrate for biohydrogen production. After acid pre-treatment of SWW using 1.5% sulfuric acid at 121ºC for 60 minutes, its glucose content increased from 0.146 g/L to 9.36 g/L. In this study, Enterobacter aerogenes (E. aerogenes) was used as the biohydrogen producer. Screening of ten physico-chemical factors that influenced biohydrogen production were performed using Plackett-Burman design tool (Design Expert 9.0). Yeast extract concentration, fermentation temperature, and inoculum concentration were ranked as the three most significant factors. The maximum hydrogen concentration, volume production, and hydrogen yield achieved in this study were 454.30 μmol/L, 88 mL, and 2.42 mmol H2/mol glucose, respectively. The findings from this study can be used for further optimization of process conditions for biohydrogen production by E. aerogenes using SWW as the substrate.
