Abstract

REYES, ELISA A. Institute of Chemistry, College of Arts and Sciences, University at the Philippines at Lao Banos, May 1420, Production of Volatile Fatty Acids from Coconut Skimmilk by Batch, Fed-Batch and Semi-Batch Anaerobic Fermentation.

Adviser: Dr. Carlito R. Barril

Production of acetic, propionic and n-butyric acids from coconut skimmilk using the batch, fed-batch and semi-batch anaerobic fermentation processes were compared. The pH of the medium was maintained between 6.0 to 6.5. Duplicate runs reveal maximum production of acetic acid at an average 2.99 g/li by the fed-batch method. Semi-batch fermentation yielded the largest amount of propionic acid at 4.94 g/li average while n-butyric acid production was highest at an average of 5.40 g/li using the batch method.

The fed-batch method produced the highest amount of total VFA at 12.49 g/li average.
