• 中文摘要： 本研究利用醱酵槽外環路上兩溶氧電極及一氣液分離器, 來估算好氣性醱酵系統之氧氣消耗速率, 並不需要使用氣體分析儀。將其與使用氣體分析儀以分析出口氣體的方法相比較, 發現兩者趨勢近似, 且此裝置具有雜訊少, 不受操作體積改變的影響, 便於線上估算與儀器成本較低等優點, 頗具實用價值。
• 英文摘要： A setup with two dissolved oxygen sensors for on-line measurement of the oxygen uptake rate in an aerobic microbial fermentation system was developed. An external loop with two dissolved oxygen sensors was linked to the fermentor. A gas-liquid separator was designed and installed in front of the dissolved oxygen sensors. The oxygen uptake rate was determined from the measured data of the dissolved oxygen without using gas analyzers.
