Abstract
A method and apparatus for calculating the growth interacting substance potency and growth ratio for the intersections of a scanning spot with a track of visible microbial colonies on an interaction plate. The potency is a measure of the weight of a growth interacting substance which is deposited on the interaction plate per unit volume of the growth culture medium. The growth ratio is a measure of the growth interacting substance effect on growth of colonies of microbes on the interaction plate along the path of interaction of the scanning spot with visible microbial colonies.
