Oatmeal Agar

Intended Use

Oatmeal Agar is used for cultivating fungi, particularly for macrospore formation.

Summary and Explanation

Fungi are extremely successful organisms, as evidenced by their ubiquity in nature. Of the estimated 250,000 species, fewer than 150 are known primary pathogens of humans.1
Identification and classification of fungi is primarily based on the morphologic differences in their reproductive structures.2 Fungi reproduce by producing spores.2 Large, multi-celled spores are called macroconidia, macroaleuriospores or macrospores and are produced by aerial sporulation.2 The detection of fungi is a great concern in the pharmaceutical, food and cosmetic industry.

Principles of the Procedure

Oatmeal is a source of nitrogen, carbon, protein and nutrients. Agar is the solidifying agent.
