Title:
INHIBITION OF FUNGAL GROWTH BY MANGANESE DEPLETION
Document Type and Number:
WIPO Patent Application WO/2019/202003
Kind Code:
A3
Abstract:
The present invention provides a method of controlling growth of unwanted microorganisms by limiting their access to manganese. More specifically, the present invention provides a method of inhibiting or delaying growth of yeast and mold by reducing the manganese concentration in a product which is preferably a food product. The invention also provides manganese scavengers and uses thereof to inhibit or delay fungal growth. The manganese scavenger may be a bacterial cell, specifically a lactic acid bacterial cell, more specifically Lactobacillus rhamnosus alone or in combination with Lactobacillus paracasei.
