eb Bioactive peptides and proteins such as insulin [1], inter-feron [2,3] and erythropoietin [4] are used as curative method of producing large quantities of peptides or proteins is by fermentation of recombinant microorgan-Pandey et al.

This is especially seen when the peptide ofPowder Mill Road and Route 141, Wilmington, DE, USA Full list of author information is available at the end of the articleagents in many therapeutic applications. Other peptides and proteins have found uses in a variety of industrial applications such as the pulp and paper industries and personal care industries [5]. Peptides are traditionally prepared by chemical synthesis or isolated from natural sources. Such methods are often expensive, time con-suming, and characterized by a limited production isms that express a gene encoding the peptide or protei
