Researchers at the College of Environmental Science and Engineering of Nankai University have introduced a new strategy to realize rapid biochemical oxygen demand (BOD) measurement by using the competitive switching of electrotrophic and heterotrophic pathways of facultative bacteria. The findings were published in Water Research under the title "Switchover of Electrotrophic and Heterotrophic Respirations Enables the Biomonitoring of Low Concentration of BOD in Oxygen-rich Environment."
