Transient Transmembrane Secretion of H2O2: A Mechanism for the Citral-Caused Inhibition of Aflatoxin Production From Aspergillus Flavus

Chem Commun (Camb). 2015 Dec 21;51(98):17424-7. doi: 10.1039/c5cc07475d. Epub 2015 Oct 15.

Abstract

A polydopamine-Fe3O4 nanocomposite-based H2O2 electrochemical sensor is fabricated to real-time monitor the transmembrane release of reactive oxygen species from citral-treated Aspergillus flavus, revealing a mechanism involving transient transmembrane secretion of H2O2 for the citral-caused inhibition of aflatoxin production from a fungus for the first time.
