Bacteriocins are potent antimicrobial peptides produced by every bacterial and archeal species reported to date. The most studied are bacteriocins produced by lactic acid bacteria (LAB) and many species of Bacillus. Knowledge on the classification, biosynthesis and transport of these peptides is changing continually because the discovery and characterization of new bacteriocins increases, thus, the research reports increase at the same rate. The bacteriocins are considered the most promising molecules with enormous possibilities and realities for the design of improved antibiotics possessing specific characteristics, mostly against antibiotic resistant bacteria. Here, current information on the generalities, classification proposals, biosynthesis and transport systems involved in the bacteriocins secretion is review. Finally, this review will focus on the new approaches for its application in veterinary medicine and human health.
The microbiology of the rhizosphere has been investigated since 1904, revealing innumerable rhizomic microorganisms that promote growth in swamps (RPCPs), which have attracted a special interest to improve agroecological practices, crop productivity and protect soils from environmental contamination under a agricultural sustainability approach. This review addresses a topic as extensive as it is fascinating, beginning with the characteristics of soil microbiology. It also describes how RPCPs associated with plant roots offer greater crop growth through direct and indirect strategies. Also mention the complexity of plant growth and how it is done simultaneously through numerous metabolic activities. The bacterial genera of RPCP, the metabolic characteristics and the potential of entomopathogenic bacteria Bacillus thuringiensis (Bt) to be considered as RPCP are mentioned. Finally, the little known properties of Bt are exposed to benefit the growth of plants, their effectiveness in biocontrol of phytopathogens, as biofertilizers and / or biostimulants in crops. New perspectives are proposed to develop Bt products as a growth promoter in the near future. It is important to recognize that applied research of rhizosphere crops can be one of the key factors in achieving the sustainable yield of agriculture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
