Abstract

Evaluation of the effect of chitin on the ethanol fermentation performance of the non-flocculating yeast. Saccharomyces cerevisiae HBY3 was done using 2ᵏ factorial experimental design. Results of Analysis of Variance and Duncan's Multiple Range Test showed that chitin significantly affects ethanol yield in both preliminary and main flask fermentation. Supporting analysis for total residual sugar concentration, viable cell count also showed significant difference between fermentation set-ups with and without chitin. Addition of chitin results to ionic binding of cells to chitin particles promoting cell immobilization. Moreover, chitin also induces flocculation on S.cerevisiae HBY3. These two factors greatly attribute to the increase in ethanol yield. Among the different percent chitin supplementation, 0.2% chitin gave the highest ethanol yield of 6.70% (v/v).
