They can be found evenly spread all over the take a look at tube. Thioglycolate broth is usually a multipurpose, enrichment, differential medium used mainly to ascertain the oxygen needs 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 top with the broth, makes A variety of oxygen concentrations inside the medium together its depth. The oxygen focus at a provided level is indicated by a redox-delicate dye including resazurine that turns pink from the existence of oxygen.
