Abstract
A broth medium for the detection of DNAse-positive microorganisms. The medium contains conventional nutrients for growing the microorganisms, a source of essential divalent cations to insure activity of the DNAse and a biological indicator comprising DNA, toluidine blue and lambda carrageenan in sufficient quantity so that the medium turns from blue to a visually distinguishable reddish-pink or reddish-violet color in the presence of DNAse-positive microorganisms.
