✦ Synopsis

Su.mmary

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 34.5oc 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.

High ethanol and stillage solids have been achieved using whole corn mashes. Ethanol yields of 14% (v/v) (89.5% of theory) and stillage levels of approximately 23% (w/v) were obtained in 74-90 hours using mild acid pretreatment with Aspergillus oryzae wheat bran koji saccharification. High ethanol y
