Microbes in the soil Microbial in water microbes in the air and other, that are linked to each other and the relationship in all aspects.
Determination of microbial substrate by using McFarland Standard turbidity compared to a similar standard to determine the amount of bacteria was 1×〖10〗^8 CFU / ml for use in quality control within the laboratory. In order to determine the amount of bacteria in the range of a standard that allows performance testing microbes in the test more efficient, such as quality control culture or Quality control agar plates and test the effectiveness of the UV lamp, etc.
