The use of lactic acid bacteria (LAB) as bioprotective cultures can be an alternative to chemical preservatives or antibiotic to prevent fungal spoilage in dairy products. Among antifungal LAB, Lactobacillus harbinensis K.V9.3.1Np showed a remarkable antifungal activity for the bioprotection of fermented milk without modifying their organoleptic properties (Delavenne et al., 2015). The aim of the present study was to elucidate the action mechanism of this bioprotective strain against the spoilage yeast Yarrowia lipolytica. To do so, yeast viability, membrane potential, intracellular pH (pHi) and reactive oxygen species (ROS) production were assessed using flow cytometry analyses after 3, 6 and 10 days incubation in cell-free supernatants. The tested...

The data presented are associated with the "Proteomic analysis of the adaptative response of Mucor spp. to cheese environment" (Morin-Sardin et al., 2016) article [11. Mucor metabolism is poorly documented in the literature and while morphology and growth behavior suggest potential adaptation to cheese for some strains, no adaptation markers to cheese environment have been identified for this genus. To establish the possible existence of metabolic functions related to cheese adaptation, we used a gel based 2-DE proteomic approach coupled to LC-MS/MS to analyze three strains from species known or proposed to have a positive or negative role in cheese production as well as a strain from a non-related cheese species.
