Research interest

Dr Labrie and his team are interested in the milk fungal microflora. Especially, they study desirable yeasts and molds involved in cheese ripening as well as undesirable ones involved in food contamination. They are developing new molecular detection methods but also use genomics and transcriptomics to determine the activity of these microorganisms in cheese and local milk ecosystems.

Characterization of milk fungal microflora. Dr Labrie and his team developed the expertise to identify and characterize foods' fungal microflora, especially milk microflora. 

Reference strain bank. Dr Labrie and his team have established a bank of over 900 fungal stains from local milk and cheeses. 

Reduction of sodium in cheeses. Dr Labrie and his team are actively working on deciphering the effect of sodium (salt) reduction in various cheese models. They wish to determine the effect on cheese's structure and on the activity of microorganisms.
