where Lcfu is the quantity of colonies about the plate Together with the lower rely (better dilution), and Hcfu is the quantity of colonies over the plate with the upper count (lesser dilution). The estimates in the cfu per mL furnished by Lcfu and Hcfu should really concur throughout the limits from the formula which has a vital worth of 1.

Every time a new item is submitted for Microbial Limits Testing (MLT), the method of decision need to first be verified to guarantee it really is suit for intent for The brand new solution
