摘要
用一种特制摇瓶可在线检测摇瓶发酵过程中N2,O2,CO2的浓度变化,继而能进一步得出过程中摄氧率(OUR),二氧化碳释放率(CER)和呼吸商(RQ)随发酵时间的变化,并以酵母菌为对象菌种进行了实验研究,结果证明该实验装置和实验方法是可靠的。
A shake flask was designed and prepared specially for the on line determination of oxygen,nitrogen and carbon dioxide concentrations in the outlet gas.So,oxygen uptake rate ( OUR ),carbon dioxide evolution rate ( CER ) and respiration quotient (RQ) were calculated by this method successfully.It shows that the apparatus and the results of above mentioned parameters measurement are relible in the flask fermentation of baker's yeast.
