Potassium Tellurite

Potassium Tellurite (K₂TeO₃) is an inorganic salt commonly used in microbiology and biochemical research. It appears as a pale yellow to white crystalline powder and acts as a selective agent in culture media, inhibiting the growth of many Gram-positive bacteria while allowing the proliferation of certain Gram-negative microorganisms.

In laboratory applications, potassium tellurite is frequently incorporated into selective and differential media for the isolation and study of pathogenic bacteria such as Corynebacterium species. Its high purity ensures reproducible results in microbial selection, diagnostic testing, and research requiring controlled growth conditions.
