Full textThe natural microbiota of cheese has often been characterized to study their potential participation in the development of sensorial properties (taste, odour, texture) of the ripened cheeses. A better understanding of their role during cheese ripening is therefore essential in order to have a better control of its quality. Few in-depth genomic analyzes have been carried out on microorganisms of the natural microflora of cheese (non-inoculated microorganisms), while there is a greater interest for inoculated ferments. The genes possessed by bacterial strains of the Quebec terroir can be revealed by the characterization of their complete genome, leading to the prediction of the associated metabolic pathways. This also allows the establishment of the individual contribution of each strain to the production of aromatic compounds. As part of this work, the complete genome of four strains of Staphylococcus equorum were sequenced. Then, a detailed analysis of the genome of these four strains was completed by their assembly and the functional annotation of the ~ 2700 genes predicted in each of the studied strains. Genes potentially implicated in proteolysis, lipolysis and lactose degradation, were found in all S. equorum strains, revealing their potential metabolisms important for cheese. Several interesting attributes of S. equorum were also identified by comparative genomic analyses. First, the relation in between the phylogenetic grouping and the source of isolation of the strains, indicates a possible adaptation of the strains to their ecological niche. The presence of unique or barely shared genes is also a distinguishable characteristic of the studied strains and can have an impact on the metabolisms of the strains. The characterization of the genome of S. equorum strains and the phylogenomic analyzes have provided new information on their role in cheese and clues about their metabolic potential. The genomic data collected will allow during future validations the selection of strains with desirable properties in function of cheese variety to yield cheeses of optimal quality.

Full textThe complex fungal ecosystems of specialty cheeses are increasingly studied because of the potential contribution of indigenous yeasts to the development of the cheese’s sensory properties. They may contribute directly or indirectly by their interaction with the funga l ecosystem or the modification of the cheese matrix. Previous studies detected Cyberlindnera jadinii, Kazachstania servazzii and Pichia k udriavzeviiin both raw milk and/or artisanal specialty cheeses from the province of Québec. The aim of this project was toanalyze the distribution of these three yeast species in cheeses made in the province of Québec. A highly specific and quantitative real time PCR assay was developed to quantitate these yeast species. The rind and the core of cheeses made in the province of Québec were sampled and analyzed using this method. Tracking of C. jadinii and P. k udravzeviirevealed that these yeasts are found within the majority of the analyzed cheeses. This study is the first step toward a better understanding of the possible contribution of these indigenous yeasts species in the development of cheese flavors, and their role in the cheese’s fungal ecosystem.

Full textL’industrie des fromages de spécialité occupe une place très importante au Québec. Sa production annuelle représente plus de 60 000 tonnes de fromages. Bien que les produits québécois se démarquent par leur haute qualité, ils manquent parfois de constances au niveau de leurs propriétés sensorielles (goût, odeur, texture, couleur). Ces variations peuvent être expliquées en partie par un déséquilibre de la microflore fromagère (bactéries et mycètes). Bien que la microflore joue un rôle majeur dans le développement des fromages, très peu d’information est disponible sur sa composition (présence et abondance relative des espèces) pour les fromages du terroir québécois. Le but de ce projet de recherche est de développer une méthode de métagénomique ciblée par séquençage massif d’amplicons (metabarcoding) pour faire la caractérisation complète de la microflore de la surface (croûte) et du coeur (pâte) de ces fromages. Le métabarcoding est une méthode d’identification qui utilise une courte séquence d’ADN représentative du génome entier. Les résultats obtenus lors de ce projet montrent que la région V3-V4 de l’ADNr 16S, pour les bactéries, et la région ITS2 de l’espaceur de transcription interne, pour les mycètes, sont les régions qui permettent de dépeindre le portrait le plus fidèle des écosystèmes fromagers. La microflore de 32 fromages du terroir québécois a été caractérisée. Les régions cibles utilisées recensent les genres dominants associés aux écosystèmes fromagers et permettent aussi la détection spécifique de certains genres moins fréquents. Le nombre de genres dominants identifiés est de 20 pour la région V3-V4, de 22 pour la région V6-V8, de 12 pour la région ITS1 et de 13 pour la région ITS2. Il a également été possible de comparer la communauté microbienne de 15 fromages pour deux années de production (2015 et 2018, 30 fromages au total) afin d’observer la variation de la microflore en fonction du temps. Cette étude a permis d’observer que plus de la moitié des écosystèmes étudiés se révèle être constante. Ces nouvelles connaissances permettent de mieux décrire la typicité des fromages québécois et de proposer des leviers technologiques aux artisans pour produire des fromages de haute qualité de façon plus constante.
The speciality cheese industry plays an important role in the province of Quebec, with a production of over 60 000 tonnes of cheeses. Although these products distinguish themselves with their high quality, a lack of constancy is sometime experienced regarding their sensory properties (taste, smell, texture, color). These variations can be explained, partly, by a microflora disequilibrium (bacteria and fungi). Even though microflora plays an important role in cheese ripening, very little information is available about his composition (presence and relative abundance of different species) for Quebec’s terroir cheeses. This research project aims to develop a targeted metagenomic by massive amplicon sequencing (metabarcoding) to characterize the microflora of cheese rind and cheese core. Metabarcoding is a profiling method using short sequences representative of the entire genome. In this project, the V3-V4 region of the 16S rDNA and the ITS2 region of the rDNA ITS region were identified as the most precise molecular markers for the profiling of respectively bacterial and fungal cheese ecosystems. The microflora of 32 cheeses of the Quebec terroir has been characterized. The target regions used identified the dominant genera associated with cheese ecosystems and also allow the specific detection of some less frequent genera. The number of dominant genus assigned is 20 for the V3-V4 region, 22 for the V6-V8 region, 12 for the ITS1 region and 13 for the ITS2 region. It was also possible to compare the microbial community of fifteen cheeses for two different years of production (2015 and 2018) in order to observe the variation of the microflora over time. This study shows that over half of the ecosystems analyzed are stable. This new knowledge allows a better understanding of Quebec’s terroir cheese typicity and offers new information to cheesemakers on the way to produce high quality cheeses more consistently.

Full textWhy only a third of Canadian adults consume on a daily basis at least two servings of milk and alternatives? What explains their consumption? In the present study, most men and women (n = 161) reported being sensitive to health effects and taste, feel sometimes approval, sometimes disapproval from their immediate entourage and consider price and reducing confidence as a barrier. Their perceptions were different for milk and cheese; drinking milk was more associated with children, cognitive reasons and raised more questions, whereas cheese was more associated with pleasure, adults, was more convenient and facilitated by the food supply. These findings highlight salient beliefs underlying milk and cheese consumption and will contribute to support the effectiveness of strategies promoting an optimal consumption of these foods among the population.
