黑曲霉菌 (Ａｓｐｅｒｇｉｌｌｕｓｎｉｇｅｒ)是一种不产生黄曲霉毒素的丝状真菌 ,它有生长迅速、易于培养、可大量产生分泌性蛋白质的特点 ,因此它除了在生产各种真菌代谢物及酶类的发酵工业上被广泛应用外 ,在基因工程中作为宿主菌生产蛋白质产物方面也受到很大重视和应用。 Aspergillus niger is a non-aflatoxin-producing filamentous fungus that grows rapidly, is easy to grow and produces large quantities of secreted proteins. Therefore, it not only produces various fungal metabolites and enzymes Fermentation industry is widely used, in gene engineering as host bacteria produce protein products also received great attention and application.
