Evaluation of the heavy metal resistant on biosensors for the purpose of biochemical oxygen demand measurements
The biochemical oxygen demand (BOD) sensor based on an immobilized mixed culture of microorganisms in combination with a dissolved oxygen electrode has been developed for the purpose of on-line monitoring of the organic pollution of wastewater. A general problem of all commercial BOD sensors is in measuring samples containing heavy metal ions. The result of this study clearly demonstrates the need of the use of heavy metal resistant strains like Alcaligenes Eutrophus, while measuring the BOD of wastewater contaminated by heavy metal.
