Measuring Biochemical Oxygen Demand (BOD) is a method used for
estimating the amount of organic matter in sewage water
working out the efficiency of oil driven automobile engines
measuring the activity of Saccharomyces cerevisae in producing curd on a commercial scale
working out the efficiency of RBCs about their capacity to carry oxygen
Solution
Decomposition of organic matter by microbes requires oxygen. The degree of impurity of water due to organic matter is measured in terms of BOD (Biochemical Oxygen Demand) or BOD is the oxygen in milligrams required for five days in one litre of water at $20^{\circ} \mathrm{C}$ for the microorganisms to metabolise organic waste.
