through which Lcfu is the volume of colonies over the plate with the lessen depend (larger dilution), and Hcfu is the amount of colonies within the plate with the higher depend (lesser dilution). The estimates on the cfu per mL provided by Lcfu and Hcfu should concur in the limits in the components which has a significant price of 1.
