The significant
advantage of AMPs resides in the global mechanism of their action,
which is remarkably different from that of conventional antibiotics.
Usage of AMPs will gain widespread increase since more and more
bacteria may develop the ability to resist conventional antibiotics
due to the abuse of these drugs worldwide. Since the first AMP
Cecropin was discovered from Hyalophora cecropia in the 1980s by
Boman’s research group, a large number of antimicrobial peptides,
which share common features such as relatively low molecular
weight, positive charge and inducibility by injury and microorganism
infection, have been identified
