cyclic lipopeptides

Assessment of the ability of Bacillus velezensis bacteria to produce cyclic lipopeptides and characteristics of their growth-stimulating and bioremediation properties

In recent years, agriculture has faced the problem of fi nding promising drugs that are eff ective in combating plant diseases, alternatives to synthetic pesticides that can have a negative impact on both living organisms and the environment as a whole. To solve this problem, the possibility of using biological methods of protecting agricultural crops is being studied. In particular, special attention is paid to the search for new strains of bacteria – natural antagonists of pathogenic microorganisms that could be used instead of synthetic chemicals.

Antagonistic activity of Bacillus velezensis

A large number of synthetic pesticides have been developed to combat phytopathogenic bacteria and fungi, but their use is economically unprofi table and harms the environment. The aim of this study was to evaluate the antagonistic properties of Bacillus velezensis HR13 bacteria in relation to cultures of phytopathogenic bacteria and fungi, as well as the ability to produce cyclic lipopeptides, which have antimicrobial activity. It is shown that strain B.
