The operation of removing germs from the corns and the aceton-butanol fermentation with so treated corns were studied.1) The corns were ground to a coarse meal by roller mills, and the output of the mills was screened to separate the fine endosperm portion (containing small amounts of germs) from the course particles gathered as germs (containirg hulls and small amounts of endosperm). The yield of germs corresponded to 15% of the corns, and the recovery of them was 61.2%.2) When the mashes with the de-germed corns were allowed to ferment alone, the yields of aceton and butanol were less than those obtained from the mashes with whole corn, but when the former mashes were supplied with whole or de-fatted germs, the fermentation became better, and the suitable amounts of whole and de-fatted germs were 11.11% and 7.78% of the de-germed corns respectively.
