Abstract

Addition of L-tryptophan to cultures of the basidiomycete Oudemansiella mucida brought about a pronounced increase of production of the antibiotic mucidin. The highest increase was reached in the presence of 0.15-0.20% tryptophan and after its addition to a l-d culture. The methyl ester of tryptophan exhibited the same effect. Mycelium growing during the initial phases in the presence of tryptophan synthesized mucidin powerfully during later phases of the fermentation.

摘要

向担子菌黏奥德蘑的培养物中添加L-色氨酸可显著提高抗生素黏菌素的产量。在添加0.15 - 0.20%色氨酸并将其添加到对数期培养物后，产量达到最高增长。色氨酸甲酯也表现出相同的效果。在发酵前期于色氨酸存在下生长的菌丝体，在发酵后期能大量合成黏菌素。
