Bacillus sp. Bacteriocins: Natural Weapons against Bacterial Enemies

Background: Currently antibiotic resistant pathogenic bacteria are emerging as an important health problem worldwide. The search for new compounds with antibiotic characteristics is the most promising alternative. Bacteriocins are natural compounds that are inhibitory against pathogens, and Bacillus species are the major producers of these compounds, showing antimicrobial activity against clinically important bacteria. These peptides not only have potential in the pharmaceutical industry but also in food and agricultural sectors. Objective: We provide an overview of the recent bacteriocins isolated from different species of Bacillus including their applications and older bacteriocins. Results: In this review, we have revised some works about the improvements carried out in the production of bacteriocins. Conclusion: These applications make bacteriocins very promising compounds that need to study for industrial production.
