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.

We characterized the carbohydrate-fermenting ability of 31 strains of Shiga toxin-producing Escherichia coli (STEC) O26 isolated from diarrhea patients in Aichi Prefecture, Japan, in order to establish selective isolation media for these strains. None of the 31 STEC O26 strains

The nucleotide sequence of a 4,539 bp fragment of Bacillus stearothermophilus V mediating tellurite resistance in Escherichia coli was determined. Four ORFs of more than 150 amino acids encoding polypeptides of 244, 258, 308, and 421 residues were found in

Biochemical, genetic, enzymatic and molecular approaches were used to demonstrate, for the first time, that tellurite (TeO(3) (2-)) toxicity in E. coli involves superoxide formation. This radical is derived, at least in part, from enzymatic TeO(3) (2-) reduction. This conclusion

The effects of potassium tellurite on growth and survival of rho(+) and rho(0) Saccharomyces cerevisiae strains were investigated. Both rho(+) and rho(0) strains grew on a fermentable carbon source with up to 1.2 mM K(2)TeO(3), while rho(+) yeast cells grown

A selective enrichment broth (SVV) was formulated to allow concurrent growth of Salmonella spp., V. parahaemolyticus, and V. cholerae. Potassium tellurite and sodium citrate were added as the inhibitors, while glucose, mannitol, anhydrous sodium sulfite and sodium pyruvate were employed
