黑曲霉作为细胞工厂:知识准备与技术基础

黑曲霉是一种重要工业微生物,在酶制剂、异源蛋白、有机酸等领域应用广泛。2007年黑曲霉基因组的公布将黑曲霉的研究引入后基因组时代,各种组学数据如雨后春笋般涌现,人们对黑曲霉高效生产机制的理解上升到系统、分子层次;与此同时,黑曲霉遗传操作系统也不断成熟,为系统地研究和改造黑曲霉、将黑曲霉打造成通用细胞工厂奠定了基础。

Aspergillus niger as a potential cellular factory: prior knowledge and key technology

Aspergillus niger is an important industrial workhorse with extensive application in the sectors of industrial enzymes, heterogeneous proteins, organic acids and etc. The disclosure of its genomic sequence to the public brought the study of A. niger into the post-genomic era. Diverse omic data are being produced massively and rapidly, which largely upgrades our understanding to the hyperproduction mechanism of A. niger to a systems and molecular level. At meanwhile, its genetic operating system is becoming mature, which enables genome-scale genetic perturbation within A. niger. In conclusion, we are on the right way to redesign and engineer A. niger to an omnipotent cellular factory.
