The Restoration with the organism from constructive product Management will not be fewer than 75% compared With all the Restoration of organisms from constructive control.
Antimicrobial brokers current in test samples can impression the results with the USP sixty one test. To overcome this challenge, this test strategy also takes advantage of neutralization and dilution techniques to make certain that antimicrobial agents of the product or service must not inhibit the growth of suspected microorganisms in samples.
