Abstract
Ethanol fermentation studies were conducted with Saccharomyces cerevisiae ATCC #4126, to determine the optimal conditions of oxygen tension and feed sugar concentration. In long‐term continuous culture maximum ethanol production was found to occur at 0.07 mmHg oxygen tension and 10% glucose feed concentration. Preliminary process design and cost studies are developed for industrial scale fermentations to produce ethanol and torula yeast from sugars obtained by enzymatic hydrolysis of newsprint.
