EMERSON YSS AGAR

Fungi were among the first microorganisms recognized because some of the fruiting structures, such as the mushrooms, are large enough to be seen without a microscope. Fungi are extremely successful organisms, as evidenced by their ubiquity in nature. They are an important component in the energy cycle where they function as decomposers. Actinomycetes are distributed worldwide, found as part of the indigenous microflora found in soil, mud etc. and also as parasites of humans and other animals.
Emerson YSS (Yeast Soluble Starch) Agar recommended for the isolation of Actinomycetes and other fungi was formulated by Emerson. This medium was used in half strength by Emerson and Wilson to obtain single germlings from zygotes or zoospores.
