The wild strain requires biotin and thioamine but usually not purine. Growth was stimulated slightly by 5 μ respectively per 10 ml of culture medium. These substances did not inhibit spore germination but retarded growth of the hyphae. The relation between nutritional requirements of microorganisms and the action of purine antagonists and the problem of the chemical structure of the compounds required as metabolic antagonists are discussed.
