Aspergillus Niger is an important fermentation microbial ,which is widely used in industrial enzymes'production and organic acid fermentation.It can produce more than 30 kinds of enzyme product such as amylase, acid protease, cellulase, pectinase and glucose oxidase. In fact, Aspergillus Niger has been applied in the field of food production for a long time.Because of its excellent ability of secreting proteins, Aspergillus Niger is developed for universal heterologous protein expression host.

As receptor bacteria of genetic engineering ,Aspergillus Niger has unique advantages upon bacteria and yeast .It's able to do majority kinds of processing after translation , and the glycosylation system is similar to that of higher eukaryotes.It's well known for high protein secretion capacity and recognized as the safe strain for heterologous protein production,in that the fermentation and post-processing technologies are mature.In addition,its genome sequences has already been published.
