Description

Cultivate aerobes and anaerobes using Thermo Scientific™ Remel™ Thioglycollate Medium (w/o Dextrose, w/o Indicator). This general-purpose medium was first described by Brewer in 1940¹ and consists of a small amount of agar and sodium thioglycolate, a reducing substance, to initiate the growth of anaerobes. Thioglycolate medium without dextrose is a carbohydrate-free medium and can be used for preparing specific carbohydrate media for fermentation studies of bacteria².

Thioglycollate Medium (w/o Dextrose, w/o Indicator) is a liquid medium recommended for use as a general purpose media. Sodium thioglycollate is the reducing agent which removes molecular oxygen from the medium and prevents the accumulation of peroxides which may be lethal to some organisms. Different carbohydrates may be added to the medium to study specific fermentation reactions.

This medium contains casein peptone and cystine that provide nitrogen and carbon compounds essential for growth of aerobes and anaerobes. A small amount of agar is added to impede oxygen diffusion. Sodium thioglycolate is the reducing agent. Sulfahydryl groups inactivate mercury and other heavy metals and neutralize the antibacterial effect of some preservatives.
