液浸培養에 依한 酒精製造에 對하여 : (第Ⅱ報) 培地選定 = Alcohol Production by the submerged Culture

국문 초록 (Abstract)

1. 液浸培養에 適當한 9種類培地로 前報에서 選定한 Aspergillus inuii, A. niger NRRL 337 및 330 을 使用하여 糖化力을 檢定하였다。
2. 培地中 C.D兩培地가 振動培養 및 Aeration培養에 있어서 다 優秀한것 같으나 一致되지않는 結果를 發見하였다。 卽 原料를 甘藷와 玉蜀黍를 組成分으로 할때에 이들 糖化力에는 何等의 影響을 주지 않었었다。
3. 培地組成分에 앞서서 培地中의 溶存酸素量이 이들 酵素生産力에 至大한 影響을 주는것 같다。
4. 本實驗에 있어서는 前報와는 달리 A. niger NRRL 337이 A. inuii보다 優秀한것 같다。

다국어 초록 (Multilingual Abstract)

1) The saccharifying activities of the previously reported strains, Aspergillus inuii, Aspergillus niger NRRL 337 and 330 were examined for nine kinds of culture media suitable for a submerged culture, under the culture conditions of shaking and aeration.
2) Although both media C and D seem to be superior to other culture media under the conditions of shaking and aeration, the result does not coincide. That is, the saccharifying activities were not affected to any extent by the difference of raw material, sweet potato and corn.
3) The dissolved oxygen in the culture media has greater effect on the production of enzymes than the composition of the media does.
4) Aspect from the previous report, A niger NRRL 337 seems to be better in saccharifying activities than A. inuii in these experiments.
