General description

Potassium Tellurite Solution is a sterile, filter-sterilized 1 % solution specifically designed for the selective isolation of Staphylococcus and Corynebacteria in microbiological applications, complying with ISO 6888-1:2020 standards. Its selectivity arises from the inhibitory action of potassium tellurite against many gram-negative and some Gram-positive bacteria, allowing only the target organisms to thrive. Staphylococci and Corynebacteria can metabolize potassium tellurite, reducing it to telluride and forming distinctive black colonies, which aids in differentiation. This optimized solution provides an environment conducive to the growth of these bacteria while suppressing others.

Application

Potassium tellurite Solution is widely used in environmental, food and beverage, and microbiology industries for the selective isolation of Staphylococci and Corynebacteria.
