Will Obligate Anaerobes Grow In Thioglycollate Medium?

Why will obligate anaerobes grow in thioglycolate? The free sulfur will tie up atmospheric oxygen, leaving the bottom of the medium anaerobic. … Escherichia can grow anaerobically by fermentation and aerobically by using oxygen as the final electron acceptor in respiration.

What type of organism is growing in this tube of thioglycollate?

Aerobic and anaerobic bacteria can be identified by growing them in test tubes of thioglycolate broth: Obligate aerobes need oxygen because they cannot ferment or respire anaerobically. They gather at the top of the tube where the oxygen concentration is highest.

What grows in fluid thioglycollate medium?

Fluid Thioglycollate Medium is a general-purpose medium for the cultivation of anaerobes, microaerophiles and aerobes, and is recommended as one of the media for the sterility testing of biologics.
