Ethanol Production from Glucose in an Immobilized Yeast Fermentations System with Pyruvate and Acetaldehyde as Supplements

Abstract

Present study deals with the quantitative production of ethanol from pyurvate and acetaldehyde separately before and after supplementing with glucose. Statistical analyses indicate three aspects: (i) determination of mean yield before the addition of intermediates, (ii) determination of significant variation after the addition of intermediates, and (iii) calculation of new mean yield. Ethanol production increase was statistically significant after that addition of intermediates. Maximum production was obtained when the glucose was added along with pyruvate (P>0.05 level). Hence, it is evident that addition of pyruvate along with glucose in the fermentation medium statistically increases the ethanol yield.
