Question

Measuring BOD is a method used for a- working out the efficiency of oil driven automobile engines b- measuring the activity of saccharomyces cerevisae in producing curd on a commercial scale. c- working out the efficiency of RBCs about their capacity to carry oxygen d- estimating the amount of organic matter in sewage water.

Answer 1

BOD is the biochemical oxygen demand, which is the amount of oxygen dissolved in a given amount of water at a specific temperature over a given period of time that is required for for the biological break down of organic matter by aerobic microorganisms. Therefore BOD might be used to estimate the amount of organic matter in a sewage system(d).
