Antimicrobial Peptides From Different Sources: Isolation, Purification, and Characterization to Potential Applications

ABSTRACT Antimicrobial peptides (AMPs) are excellent promising candidates for biomedical applications owing to their structural properties, high biocompatibility, good biodegradability, and functional diversity. Unlike conventional antibiotics, AMPs have been shown to have broad‐spectrum antimicrobial activity toward Gram‐positive/negative bacteria, as well as antifungal and antiviral activity. These peptides have also been found to be cytotoxic to sperm and cancer cells. A range of AMPs has been isolated from various organisms, such as bacteria, fungi, plants, and animals. This review summarizes the latest studies on AMPs, covering their isolation, purification, and characterization as well as their potential biomedical applications and beyond.
