✦ Synopsis

A study of the feasibility of utilizing palm oil waste as a substrate for acetonebutanol-ethanol fermentation by Clostridium saccharoperbutylacetonicum N1-4 and, hence, to reduce the biochemical oxygen demand (BOD) of waste disposal was carried out. Among the two types of palm oil waste tested, separator sludge was the better substrate and it was able to support production of solvents by C. saccharoperbutylacetonicum N1-4 without a need for any mineral supplements. Enzymatic hydrolysis catalyzed by cellulase prior to fermentation was found to increase the yield of butanol by 75% (from 2.47g/I to 4.37g/I) and decreased the BOD by 66% (from 26,500 ppm to 8,900 ppm).
