Iturin is a type of lipopeptide antibiotic produced by certain strains of the bacterium Bacillus subtilis. It is known for its antifungal properties, making it effective against various fungal pathogens. Iturin works by disrupting the cell membranes of fungi, leading to their death and preventing the spread of infections. In addition to its antifungal activity, Iturin has potential applications in agriculture as a biopesticide. Its ability to inhibit fungal growth can help protect crops from diseases, reducing the need for chemical fungicides. This makes it a valuable tool for sustainable farming practices.
