巯基乙酸培养基(厌氧培养基)

Thioglycollate Medium is a powdered broth medium designed for the cultivation of both aerobic and anaerobic microorganisms. The medium contains dextrose, tryptone, yeast extract, and L-cystine providing essential growth factors for bacterial proliferation. Sodium thioglycollate and L-cystine serve as reducing agents that prevent the accumulation of lethal peroxides, enabling the growth of Clostridium even under aerobic conditions. Resazurin acts as an oxidation-reduction indicator, appearing pink when oxidized and colorless when reduced. The minimal amount of agar in the medium supports the growth of both aerobes and anaerobes, regardless of the presence of sodium thioglycollate. Sodium thioglycollate also neutralizes the toxic effects of mercurial preservatives and peroxides, promoting anaerobiosis and making the medium suitable for testing materials containing heavy metals. Any increase in oxygen content is indicated by a color change in resazurin from colorless to pink. The small agar content helps maintain a low redox potential, stabilizing the medium.
