Abstract

The present invention relates to a device and method of detecting microorganisms in a rapid manner and increasing the number of microorganisms detected during the culturing of a sample by the addition of resinous and non-resin adsorbents and molecular sieves in the growth media. These agents have been found to neutralize or remove inhibitory and antimicrobial substances found in samples and media.
