From the test Alternative group, the solution is filtered from the membrane filter, accompanied by two one hundred-mL portions of diluting-neutralizing fluid. Immediately after the second rinse has actually been filtered, a ultimate 100-mL part containing fewer than a hundred click here cfu of the precise obstacle microorganism is handed in the filter.
