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.

Potassium tellurite is highly toxic to most forms of life and specific bacterial tellurite defense mechanisms are not fully understood to date. Recent evidence suggests that tellurite would exert its toxic effects, at least in part, through the generation of

Potassium tellurite (K(2)TeO(3)) is harmful to most organisms and specific mechanisms explaining its toxicity are not well known to date. We previously reported that the lpdA gene product of the tellurite-resistant environmental isolate Aeromonas caviae ST is involved in the

Potassium tellurite (K(2)TeO(3)) is extremely toxic for most forms of life and only a limited number of organisms are naturally resistant to the toxic effects of this compound. Crude extracts prepared from the environmental isolate Aeromonas caviae ST catalize the
