  "abstract": "<p>E-Poly-L-lysine (E-PL) is a cationic peptide with a broad-spectrum antimicrobial activity. This study<br>\ninvestigates the use of E-PL as natural antimicrobial to inhibit fungal growth and to reduce aflatoxins<br>\n(AFs) production. Antifungal activity of starch biofilms with different concentrations of E-Poly-<br>\nL-lysine (E-PL) was determined in solid medium against Aspergillus parasiticus (AFs producer) and<br>\nPenicillium expansum. Then, biofilms were tested as antimicrobial devices for the preservation of<br>\nbread loaf inoculated with A. parasiticus CECT 2681 and P. expansum CECT 2278. Shelf life and<br>\nAFs content were examined. Biofilms with concentrations of E-PL less than 1.6 mg/cm2 showed<br>\nno fungal growth inhibition in solid medium, while the antifungal activity of the films with greater<br>\nthan 1.6 mg/cm2 of E-PL was dose dependent. The shelf life of bread inoculated with A. parasiticus<br>\nwas increased by 1 day with the use of films containing 1.6\u20136.5 mg E-PL/cm2, while shelf life of<br>\nbread tainted with P. expansum was increased by 3 day with 6.5 mg E-PL/cm2. AFs production<br>\nwas greatly inhibited by E-PL biofilms (93\u2013100%). Thus, E-PL biofilms could be potentially used as<br>\nantimicrobial device during bread storage as a natural alternative to the synthetic preservatives.</p>",
