Sabouraud agar is mainly used to grow dermatophytes and other types of yeasts and molds. Sabaroudagar can also be used to grow filamentous bacteria, e.g. species within the genus Nocardia.

The medium contains:

  •  dextrose (which is another name for D-glucose)
  •  peptone (hydrolyzed proteins, which contains short peptodes and amino acids)
  •  agar (jelly-forming substance)

The pH of the medium should be 5.6 and this relatively low pH inhibits the growth of many bacteria.

Other comments

This medium is not always recommended for primary isolation, as it is not nutritious enough for some fastidious fungi. This is especially true for many of the dimorphic fungi.
