Abstract

The fungus Aspergillus produces several metabolites that are either primary or secondary. Enzymes which are primary metabolites of Aspergillus have found applications in food and beverage industries. While secondary metabolites like aflatoxins and mycotoxins are detrimental some of the antibiotics like penicillic acid and mellein have found pharmaceutical applications for treating Mycobacterial and Staphylococcal infections. Development of Aspergillus strains for metabolite production has been known for long. Essentially, strain improvement programme aims to refine fungal growth under defined fermentor conditions. Invariably, such studies concentrate on the product of interest in relation to increased productivity under growth in cheap media conditions. Aspergillus carbonarius has been used as a fungus for industrial polygalacturonase production. Strain improvement focused on obtaining higher enzyme productivity resulted in variants secreting another metabolite that had both food and pharmaceutical applications.
