Competition-Exclusion for Manganese Is Involved in Antifungal Activity of Two Lactic Acid Bacteria Against Various Dairy Spoilage Fungi.

ABSTRACT: Biopreservation using lactic acid bacteria has gained a growing interest as an alternative to chemical preservatives and/or as a complementary tool to prevent fungal spoilage in dairy products. Among the action mechanisms of antifungal LAB, competitionexclusion for trace elements has recently been highlighted. To further investigate this mechanism, two antifungal LAB strains, Lactiplantibacillus plantarum L244 and Lactobacillus rhamnosus CIRM-BIA1759, were studied in a yogurt model. Firstly, the antifungal activity of these strains against four main dairy spoilage fungi (Penicillium biforme, Mucor racemosus, Galactomyces geotrichum and Yarrowia lipolytica) was evaluated with or without trace element (6 metals and 12 vitamins) supplementation.
