A relationship between temperature and high ethanol yields has been found using whole corn mashes saccharified with Aspergillus oryzae wheat bran koji. Decreased ethanol yields were obtained at 34.5°C with high concentration corn mashes in contrast to high ethanol yields with the same medium at lower temperatures. The decreased yields appear to be related to mass and/or heat transfer problems rather than primary ethanol toxicity. Scale-up of the high corn medium will require a re-evaluation of alcohol fermentation technology.
