• 中文摘要： 研究嫌氣對 Zymomonas mobilis, ATCC 29191 醱酵葡萄糖生產酒精之影響，發現酒精之產量次序為於空氣中振盪培養＞空氣中靜置培養＞氮氣下靜置培養＞二氧化碳下靜置培養。 於醱酵槽中同時通氣及攪拌將減低酒精產量及比酒精生產速率但增加菌體收量。如單獨攪拌，含23%葡萄糖培養其經28小時之醱酵可獲得100g/1之酒精量及醱酵效率可達85.38%
• 英文摘要： In studing the effect of anaerobiosis onthe production of ethanol by Zymomonasmobilis. ATCC 29191, it was found that theethanol yield was in an order of shakenculture in the air＞static culture in the air＞static culture in nitrogen＞ static culture inIt indicates that strain ATCC 29191 isa facultatively anaerobic organism and alimited amount of oxygen is required toenhence the cell growth. Simultaneous aeration and agitation in ajar fermentor would reduce ethanol yield andspecific ethanol production rate, but increasecell yield. With agitation only, 100 g/1 ofethanol was produced in a medium containing23% glucose after 28 hr fermentation, andthe fermentation efficiency was up to 85.38%.
