用ＰＶＡ、纤维素等材料将从土壤中分离得到的一株好氧乙醇菌包埋，制备的微生物膜与极谱型氧电极结合，制成乙醇微生物电极，其线性范围为 ０．３～１２．０ ｍｇ／Ｌ，响应时间小于５ｍｉｎ，测定的最适宜ＰＨ为６．４～７．３，电极连续使用三个月信号基本稳定。用该电极测定啤酒等样品的结果与气相色谱法具有可比性。
An aerobic ethanol bacteria isolated from soil was embedded with PVA, cellulose and other materials, and the prepared microbial membrane was combined with polarographic oxygen electrode to produce ethanol microbial electrodes with a linear range of 0.3-12 .0 mg / L, the response time is less than 5min, the most suitable measurement of PH 6.4 ~ 7.3, the electrode three months continuous use of the signal is basically stable. The results of measuring beer and other samples with this electrode are comparable to those of gas chromatography.
