Like most bacteria, the nutrition of fungi is heterotrophic and absorptive, and in many environments microbial fungi and yeasts
are closely associated with bacteria and compete with them.
Fungi have been the material with which many fundamental biological discoveries have been made. In addition to having a role in fundamental biological research, fungi are of great practical importance. In most natural ecosystems there are fungi associated
with the roots of plants which help to take up nutrients from soil, and the decomposition of plant litter by fungi is an essential part of the global carbon cycle. Also, fungi cause some of the most important plant diseases, and hence receive much attention from plant pathologists.
But, how we known if fungi make impact in our life cycle like above?
Many microorganisms have specific growth factor requirements that must be included in media for their successful cultivation. Vitamins, amino acids, fatty acids, trace metals, and blood components often must be added to media. Fungi have a many method to detections. One of it, agar culture with PDA, but another microorganism can growth to. So, we must added some antimicrobials which can suppress. Various combinations of antimicrobics are effective in suppressing classes of microorganisms, such as enteric bacteria.

Below are some of the selective agents, principally antimicrobic mixtures used for the selective isolation of pathogens.
