  • Method for testing microbial interaction with growth affecting substances
    Patent number: 4514495
    Abstract: A method for testing microbial interaction with growth affecting substances. A pattern of a microbe containing solution is applied on an interaction plate in a programmed concentration. A solution of a growth interacting substance is applied on the interaction plate in a programmed potency in a pattern which contacts the microbe containing solution to cause contact of the microbes with the growth interacting substance. The resultant plate is incubated for a time sufficient to produce visible microbial colonies on the interaction plate. The potency of a growth interacting substance is determined at any point of interest on the incubated interaction plate by correlating the position of the point of interest with the programmed volume of the growth interacting substance deposited at that point.
