Utilization of the mixtures of amino acids by helicostylum piriforme bainier

Summary The utilization of three different mixtures of amino acids was studied. Paper chromatography was employed to detect various amino acids present in the medium. The fungus grew well on all the mixtures of amino acids. The rate of growth and the final amount of mycelium produced on the first two mixtures were better than that of the same amino acids when supplied singly. On the other hand, rate of growth and the final amount of mycelium on mixture No. 3 were not better than that of all the individual amino acids.All the amino acids were completely utilized within the incubation period from mixtures 1 and 2. On the other hand, none of the amino acids could be consumed completely by the fungus from mixture 3.
