title: Inhibition of the phytopathogenic fungus Fusarium proliferatum by volatile compounds produced by Pseudomonas.
abstract: The Fusarium head blight of grain cereals is a significant disease worldwide. In Argentina, high levels of contamination with Fusarium proliferatum have been found in crops. Many strains of the Pseudomonas genus antagonize the growth of fungi by different mechanisms, such as the production of antibiotics, siderophores, volatiles, and extracellular enzymes. In this work, we have designed a new system for studying the growth inhibition of F. proliferatum-namely by volatile compounds produced by Pseudomonas fluorescens MGR12. In both rich and minimal media, the bacterium released volatiles that negatively affected the mycelial growth of that phytopathogenic fungus. These bacterial compounds were analyzed by gas chromatography-mass spectrometry, but only a few could be identified by comparing their mass spectra with the libraries of the National Institutes of Standards and Technology MS search.
