RAPID MEASUREMENT METHOD FOR BIOCHEMICAL OXYGEN DEMAND (BOD) BY USING SACCHAROMYCES CEREVISIAE AS BIOLOGICAL RECOGNITION ELEMENTS

摘要

A rapid measurement method for biochemical oxygen demand (BOD) by using Saccharomyces cerevisiae as biological recognition elements is disclosed. The method includes: selecting Saccharomyces cerevisiae as biological recognition elements; preparing the biological recognition elements by Saccharomyces cerevisiae immobilized in polyvinyl alcohol (PVA); and rapidly measuring BOD with Saccharomyces cerevisiae immobilized in PVA. The method can be applied to rapid BOD measurement for natural water body, industrial wastewater and sea water.
