Advantages of MPN Techniques-
1. Interpretation of the results requires minimal experience and training as results can be got by simply observing for the presence of gas or no gas.
2. Water samples with high turbidity can be analyzed, since there is no apparent deleterious effect.

substances present in the sample can be diluted out.
4. MPN technique is the effective method for analyzing samples
such as muds, sludges, sediments etc.
