The entire number of aerobic organisms is decided, which is an important indicator to evaluate the hygienic top quality of medicines
in which Lcfu is the amount of colonies around the plate With all the decrease count (greater dilution), and Hcfu is the number of colonies within the plate with the higher depend (lesser dilution). The estimates in the cfu per mL provided by Lcfu and Hcfu should agree in the limits from the system by using a important worth of one.
With this stage, the entire range of aerobic organisms is set, which is a crucial indicator to evaluate the hygienic high quality of medicines.
