| 摘 要： | 本实验从活性污泥中分离筛选出一株对广泛底物具有外源呼吸的假单胞菌(Pseudomonas sp.A_4)。用该种菌株制成的BOD微生物传感器可在15min内完成一个样品BOD的测定。该法与传统方法有较好的相关性,可连续使用六周以上。

| Abstract: | A microbial sensor consisting of immobilized bacterial cells (Pseudomonas sp. A4, isolated from active sludge) and an oxygen electrode was made for the estimation of BOD. By using the sensor, the BOD of a sample solution (GGA, model waste water) could be measured within 15 minutes. The relationship between current decrease and BOD was linear in the range of 1 to 30mg/L. The relative standard deviation was about 4.1% at concentration of 10mg/L BOD. The current output of the sensor was almost constant for 4 weeks, and practically, it could be used over 6 weeks, 400 tests, with additional calibration. |
