Abstract

PEREZ, Ma Elaine A. 1985. Optimization of the Production of Volatile Fatty Acids from Coconut Water by Batch Anaerobic Fermentation. An undergraduate thesis presented in partial fulfillment of the requirements for the degree of Bachelor of Science in Chemistry under Dr. Carlito R. Barril, University of the Philippines at Los Banos. Second Semester, 1984-85.

The effects of ph, dilution of substrate and retention time on the production of acetic, n-butyric and propionic acids from coconut water by batch anaerobic fermentation were determined. Acetic acid was found to have a maximum percentage production of 75.50% or 8.23 g/1 at p11 6.0; 78.61% or 6.91 g/1 at 1:1 (coconut water: diluent) dilution; and 77.31% or 8.28 g/1 at a retention time of 24 hours. Propionic acid has a maximum percentage production of 16.10% or 4.3=3 g/l at pH 5.5; 30.04% or 0.73 g/i at 1:9 dilution; and 12.20% or 1.17 g/1 at a retention time of 20 hours. On the other hand, n-butyric acid has a maximum percentage production of 24.93c/ or 0.43 g/1 at ph 5.0; 18.52% or 0.45 A/1 at 1;9 dilution ; and ,t r, retention time of 28 hours.
