POTASSIUM TELLURITE FOR MICROBIOLOGY
Potassium tellurite acts as a selective agent and has inhibitory activity against most gram-positive and gram-negative bacteria except Corynebacterium species.
diphtheriae reduces potassium tellurite to tellurium and thereby produce gray-black coloured colonies
Potassium tellurite, K2TeO3, is an inorganic potassium-tellurium compound. It has been used as a selective growth medium in microbiology.
