Beskrivning

The genus Aspergillus has a worldwide distribution and is one of the most common of all groups of fungi. Traditional methods of strain develop ment have been extensively studied with the industrial strains, while more recently, recombinant DNA technology has been applied to the aspergilli with emphasis on heterologous protein production.
