Abstract

The effect of pH, dilution of substrate and fermentation time time on the production of acetic acid, n-butyric and propionic from coconut skimmilk by batch anaerobic fermentation were determined. Acetic acid was found to have a maximum production of 46.00 g/li at pH 6.0 at substrate dilution ration of 1:0 (CSM-H2O) after 24 hours of fermentation. Propionic acid reached highest production of 30.12 g/li under the same conditions of pH, substrate dilution and fermentation time, while butyric acid had a maximum production of 14.04 g/li at pH 6.0 and 1:0 dilution ratio but after 48 hours of fermentation. The relative concentrations of the VFA produced after 24 hours of fermentation were 51.02% for acetic acid, 33.41% for propionic acid and 15.57% for butyric acid. The optimum conditions for total volatile fatty acid production were found to be at 1:0 dilution, pH 6.0-6.5 at a fermentation time of 24 hours.
