Excessive nitrogen commonly leads to eutrophication and harmful algal blooms, causing a large amount of chlorophyll production. In this study the use of chlorophyll as redox mediator for denitrification was investigated. Results showed that the nitrate and nitrite reduction rates were enhanced 7.26-fold and 7.31-fold with 0.02 mM chlorophylla(Chla), respectively. Compared to the control system, the electron transfer rate of the Chla-supplemented denitrification system was improved, as demonstrated by a smaller peak separation in cyclic voltammetry analysis. The lower stable pH and higher stable ORP in the Chla-supplemented denitrification assay might suggest that Chlaaffected the electron transfer path in denitrification. A sequencing batch experiment showed good reusability and biocatalytic effects of Chla. Furthermore, the leaves and extracted chlorophyll can also enhance denitrification. This study provides new insight for the application of chlorophyll and a potential strategy for the management of eutrophicationin situ.
