Thioglycolate broth can be a multipurpose, enrichment, differential medium used generally to determine the oxygen specifications of microorganisms. Sodium thioglycolate during the medium consumes oxygen and permits The expansion of obligate anaerobes.[one] This, coupled with the diffusion of oxygen in the leading on the broth, produces An array of oxygen concentrations during the medium along its depth. The oxygen concentration at a offered degree is indicated by a redox-delicate dye such as resazurine that turns pink inside the existence of oxygen.
