Populations of those microorganisms are likely to enhance in proportion to the level of food items offered.
BOD test is performed in a temperature of 20°C. The biochemical oxygen desire (BOD) is often determined by subtracting the Preliminary DO from the ultimate DO. The Preliminary DO is recorded right away once the dilution in the sample, and any subsequent oxygen intake throughout the measurement period of time is taken into account within the calculation of BOD.
