Son after agar plate method for studying bacteria was developed it was adapted for use in determining mumbers and kinds of soil fungi. Inasmuch as bacteria and actinomycetes are relatively more numerous than fungi in most soil, it was necessary to add to the medium some material which would prevent the growth forms and still allow the fungi to grow. The best method developed, and one that has becomestandard procedure, is incorporation of a naturally acid material into the agar, or artificial acidification of the medium with an acid such as sulfuric, citric, or lactic. The artificial media most commonly used in the plate method for soil-fungus studies contain a relatively high concentration of carbohydrate, such as dextrose , and a suitable nitrogen source, such as peptone or nitrate (2, 4, 7). |
