报导了一种用于测定培养基中的养分的通用生物传感器.这种生物传感器以溶氧电极为基本传感器,在敏感膜上覆合上一种生物膜,用以测定一种假单孢菌培养液的醋酸铵的含量.其线性范围为:0~40mg/L;90%的响应时间为:15~20min;测定一个样品所需时间为40~60min;其测量精度为:±6%;使用寿命可达一年以上.
A universal biosensor for the determination of nutrients in culture media is reported.This biosensor uses a dissolved oxygen electrode as a basic sensor and overlaps a biofilm on a sensitive membrane to determine a Pseudomonas The linear range of the ammonium acetate solution is 0 ~ 40mg / L; the response time of 90% is 15 ~ 20min; the time required to measure a sample is 40 ~ 60min; the measurement accuracy is ± 6% Life of up to more than one year.
