CPC classification number: C12P13/227 , C12N9/1077 , C12Y204/02018 , Y02P20/52
Abstract: The present invention relates to a microorganism of the genus Escherichia having enhanced L-tryptophan productivity, which has been modified to express yeast anthranilate phosphoribosyltransferase in order to be able to produce L-tryptophan at high concentration, and to a method for producing L-tryptophan, comprising a step of culturing the microorganism. The microorganism of the genus Escherichia can produce L-tryptophan, and thus can be advantageously used in the pharmaceutical industry and the feed industry, particularly for animal feed.
Abstract translation: 本发明涉及具有增强的L-色氨酸生产力的埃希氏菌属微生物，其已被修饰以表达酵母邻氨基苯甲酸酯磷酸核糖转移酶，以便能够产生高浓度的L-色氨酸，以及L-色氨酸的生产方法 包括培养微生物的步骤。 埃希氏菌属的微生物可产生L-色氨酸，因此可有利地用于制药工业和饲料工业，尤其用于动物饲料。
