摘要
研制了乙醇浓度在线监测仪 ,并对其在酵母流加生产中的应用情况进行了考察 .结果表明 ,采用乙醇浓度反馈流加培养方式 ,细胞产率和发酵活力可分别达到 0 .4 1 6g/ g和 980～ 1 1 0 0mL ,显示出良好的应用前景 .
An ethanol monitoring instrument was manufactured and its application on the production of yeast was investigated. The results show that cell yield and fermentation activity reached 0.416 g/g and 980～1 100 ml in fed-batch culture with ethanol concentration feed-back control, respectively, which indicates its great potential value for industrial application.
