Biological Oxygen Demand Sensor Using an Arsenic Resistant Bacterium

Analytical Sciences, 1990
Various microbial biosensors, including BOD (biological oxygen demand) sensors, have been reported.''2 These are usually constructed by holding intact microorganisms, such as bacteria and yeasts, near the tip of an oxygen electrode. Since microorganisms consume organic compounds quantitatively, their concentrations can be determined by estimating the ...
