Structural diversity and applications of lipopeptide biosurfactants as biocontrol agents against phytopathogens: A review

Amphipathic compounds known as biosurfactants are able to reduce surface and interfacial tensions. These substances produced by microbial organisms perform the same functions as chemical surfactants with several enhancements, the most significant of which is biocontrol activity. Lipopeptide is one of the five biosurfactants from natural resources and is identified as the best alternative for chemical surfactants and the major topic of interest for both scientific and industrial communities due to their increasingly growing potential applications in biological and commercial fields. These are the biological compounds with very less toxicity level that increase their importance in the pesticide industry. In this article we summarize the structural diversity of the microbial lipopeptide biosurfactants and focus on their applications as biocontrol agents in plants, covering (1) an intensive study of the structural diversity of lipopeptide biosurfactants originated primarily by the Bacillus, Pseudomonas, Cyanobacteria, and Actinomycetes species is presented, (2) the comparative study of advantages and disadvantages of characterization techniques and physicochemical properties which have a major role in biocontrol activity of microbial lipopeptides, and (3) their wide range biocontrol applications as systemic resistance inducers against different plant diseases, resistance against phytopathogens by alteration of wettability of plant surfaces and antimicrobial activities of important bioactive lipopeptides produced from Bacillus strains.
