Immediately after incubation depend the number of colonies in Every plate. Determine the signify and multiply it with dilution variable.
), but for every monograph There is certainly an implied reduce limit underneath which the specified solubilization impact would not manifest.

Also, you must Review the methods being used for incubation to find out whenever they conform to Those people listed in accepted or pending purposes.
If no colonies are observed express The end result as a number of colonies below dilution component. Take note down the result.
