by which Lcfu is the quantity of colonies around the plate Along with the lower count (better dilution), and Hcfu is the number of colonies on the plate with the higher count (lesser dilution). The estimates from the cfu for each mL provided by Lcfu and Hcfu really should concur in the limits on the formulation having a essential price of 1.
