Thioglycollate Medium USP (Dehydrated) is a robust, well-buffered medium compliant with USP, BP, and EP pharmacopoeia standards.

Primarily used for sterility testing, it facilitates the cultivation of both aerobic and anaerobic organisms.

Its key component, sodium thioglycollate, acts as a reducing agent and neutralizes the bacteriostatic effects of mercurial preservatives, crucial for avoiding false negative results in tests.

The medium is also recommended for cultivating Clostridium species and has shown excellent results for Desulfotomaculum nigrificans. Microbiological quality control adheres to USP, BP, EP, and ISO 11133:2014 standards.
