Abstract
Acidogenic fermentation of palm oil mill efluent (POME) can serve as a precursor in a process for production of polyhydroxyalkanoates (PHA) since the produced volatile fatty acids (VFAs) are preferred precursor for PHA production. Acidogenic fermentation of POME was studied in a 2-L reactor with semi-continuous mode operation (once-a-day feeding and draw-off) for optimal volatile acid compositions. Main fermentation products were acetic acid, propionic acid and butyric acid. The results showed acetic acid, propionic acid, and butyric acid with concentrations are 2.79 g/L; 1.18 g/L, and 3.04 g/L, respectively. VFAs that serves as a precursor on PHA production. The result of feeding of synthetic of VFAs or VFAs from POME at the 20th and 40th in a batch show the concentrations DCW and PHA are 2.38 g/L and 0.74 (g PHA/g DCW) or 2.76 g/L and 0.74 (g PHA/g DCW), respectively.
