They can be found evenly unfold through the check tube. Thioglycolate broth is actually a multipurpose, enrichment, differential medium used principally to determine the oxygen requirements of microorganisms. Sodium thioglycolate from the medium consumes oxygen and permits the growth of obligate anaerobes.[one] This, combined with the diffusion of oxygen in the top from the broth, generates A variety of oxygen concentrations during the medium along its depth. The oxygen concentration in a provided level is indicated by a redox-delicate dye like resazurine that turns pink inside the presence of oxygen.
