WebNot all bacterial cells produce colonies as some bacteria tend to clump or aggregate. For this reason results are reported as colony forming units (CFU/ml) of a bacterial culture. Only plates with 25-250 colonies are used in determination of a bacterial concentration. WebThe typically accepted number is 30–300 CFUs. Colony plate counts totalling less than 30 or more than 300 CFUs may not provide accurate estimates of bacteria. In the image below, the results of the lab shows that: of the serial dilution plates below, plate C 1 mL 1:1,000,000 would be the best plate to determine colony counts. smart asset hourly pay
