Influence of amino acids, thiourea and hydroquinone on cellulolytic activity in some Fusarium strains.

Studies were carried out on the influence of various amino acids: cysteine, cystine, methionine, alanine, serine, tryptophan, and of thiourea and hydroquinone on the activity of cellulase synthesized by four strains of Fusarium. It follows from the results obtained that the addition of amino acids, thiourea or hydroquinone to the culture media stimulates or inhibits the activity of the enzyme studied. The effect of this action depended both on the compound and the strain studied.
