The primary strategy of test for sterility is predicated on the fact that if microbes are inoculated in a clear medium which supports their expansion (i.e., the best possible temperature, pH, nutrition, and drinking water), the existence of microbes could be detected by improve in turbidity of medium, provided which the test is executed in uncontaminated problems.
