Abstract

ABSTRACT GARCIA, Minviluz L. College of Arts and Sciences, University of the Philippines at Los Banos, October, 1983. MICROBIAL PRODUCTION OF RIBOFLAVIN BY A YEAST (Candida utilis NRRL 1082) USING COCONUT WATER AS FERMENTATION 3UB:3TRATE. Adviser : Dr. Agnes F. Zamora. Coconut water was used as fermentation substrate for the microbial production of riboflavin or vitamin B2 by Candida utilis NRRL 1082. Yeast cultures were shaken on a reciprocating shaker for five days under ambient temperature and pressure. The maximum amount of riboflavin produced was 0.22 ug/ml, and this was obtained during the 36th hour of fermentation. This value is about three-fold lower than the reported literature value of 0.61 ug/ml for Candida utilis NRRL 900 using a nutrient solution composed of sucrose, ammonium nitrate (NH4NO3), and mineral salts as substrate.
