The seed (micro organism) included to each Alternative will degrade the biodegradable material in each sample relative to the level of oxygen faraway from the water. The sample dilution and quantity of oxygen removed can be employed to estimate the level of biodegradable product from the sample in mg/L. Just about every sample have to make a residual of one.0 mg/L of dissolved oxygen and have had a dissolved oxygen uptake of at the very least two.0 mg/L.
