Abstract

A process for rapidly differentiating between gram-positive and gram-negative microorganisms by mixing an anionic surfactant to inhibit the reduction capability of the gram-positive microorganisms, an electron transfer agent and a compound capable of being reduced to a detectable species by both gram-positive and gram-negative microorganisms in the absence of an anionic surfactant.
