Microbiology culture media supplements

The formulation of the culture medium includes many nutrients and substances that provide the main sources of nourishment to the microorganism, such as sugars, amino acids, nitrogen, vitamins or essential micronutrients.

For some soils or specific uses it is necessary to add enrichment supplements to the soil.

These are agents that give the medium a certain selectivity such as antibiotics, bile salts or crystal violet. Or they can be pH indicators or protective agents such as Tween 80, starch or charcoal.

The supplements allow you to make the culture medium selective or differential, or more performing or more resistant to disinfectant agents, etc.
