• 中文摘要： 氧氣傳遞與液相混合對Saccharomyces cerevisiae之培養已被探討。氣泡塔與具有不同網狀內管之氣舉式反應器,被應用於提供不同之總體氧氣傳遞係數及擴散係數。共進行了三個實驗,其中一組實驗是在相近之總體氧氣傳遞係數但不同之擴散係數下進行; 另外一組則是在相同之擴散係數但不同之總體氧氣傳遞係數下進行。實驗結果顯示,在以特性時間之表示下,對發酵而言,氧氣傳遞效應較混合效應來得顯著。
• 英文摘要： Effects of oxygen transfer and liquid mixing on cultivations of Saccharomyces cerevisiae were investigated. A bubble column and airlift reactors with different net draft tubes were applied to provide different volumetric oxygen transfer coefficients and dispersion coefficients. Three experiments were carried out. A pair of experiments was under almost the same volumetric oxygen transfer coefficients but different dispersion coefficients. Another pair was under almost the same dispersion coefficients but different volumetric oxygen transfer coefficients. Experimental results showed that oxygen transfer effect had more influence on the cultivation than mixing effect in terms of characteristic times.
