Hydrophobic compounds in neem oil fuse with lipid components of bacteria cell walls, thereby damaging cell walls and causing leakage of intracellular components.

2. Antifungal: The antimicrobial components in neem oil are reported to be potent inhibitors of the biosynthesis of aflatoxin, a naturally occurring mycotoxin that is extracted from the fungi Aspergillus flavus and Aspergillus parasiticus.
