The Progress of Microbial Biosensors for Biochemical Oxygen Demand

生化需氧量 (biochemicaloxygendemanded ,BOD)是衡量水污染程度必须测定的重要指标之一。然而 ,传统的 5d法不能及时反映排放水的污染程度。因此 ,能够快速、准确测定BOD的微生物传感器近年来得到了迅速发展。本文综述了BOD微生物传感器及其商品化仪器的发展 ,并对能使BOD传感器与传统的

Biochemical oxygen demand(BOD) is one of the most widely used and important parameters for organic pollution and is estimated with aerobic microorganisms as the catalyst for the biochemical degradation of organic matter in wastewater by determining the amount of oxygen required for this process. However, the conventional test is not suitable for process control and monitoring where a rapid feedback is desirable. To develop alternative test methods which could rapidly and adequately replace this parameter, a microbial biosensor based on the combination of immobilized microorganisms and oxygen electrode for BOD estimation was first developed by Karube et al. Since then, the BOD biosensors were, well studied. The progress of BOD microbial biosensors and commercial BOD biosensor systems was reviewed. The efforts to get agreeable results between the BOD biosensor measurement and the conventional method were also discussed.
