Abstract

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.

氨基酸、硫脲和对苯二酚对某些镰刀菌酵解纤维素活性的影响。
研究了半胱氨酸、胱氨酸、蛋氨酸、丙氨酸、丝氨酸、色氨酸以及硫脲和对苯二酚等多种氨基酸对4株镰刀菌合成纤维素酶活性的影响。结果表明,在培养基中添加氨基酸、硫脲或对苯二酚会刺激或抑制所研究酶的活性。这种作用的效果取决于所研究的化合物和菌株。
