Medium Olkenitskogo - tritsukrovy agar with urea.
Purpose: Differentiation of bacteria by the ability to ferment carbohydrates, urea and produce hydrogen sulfide.
Principle of action: The Olkennytsky environment is prepared in the form of sloped agar in test tubes. During fermentation of carbohydrates, the indicator in the environment changes the color. Depending on the part of the test tube in which the color of the medium occurred, it is possible to differentiate microorganisms. Raspberry coloration is formed when fermentation of urea. The bacteria that restore thiosulfate to sulfite acquire a black color. Agar discontinuities indicate bacterial release of gas.
