Summary: The Bacillus genus has received much attention due to its ability to act as a biocontrol agent for plant diseases. Bacillus uses several mechanisms to suppress plant pathogens, including the production of lipopeptides of antimicrobial action such as iturins, fengycins and surfactins. This study aimed to verify the production capacity of lipopeptides from the iturin and surfactin group by an isolate with known activity against root pathogens. The isolate was inoculated in nutrient broth medium and shaken for 24, 48 and 72 hours. After these periods, the samples were dried, resuspended and subjected to HPLC for quantification of metabolites compared with commercial standards of iturin and surfactin. The isolate showed the capacity to produce these metabolites at all times tested.
