Criteria used are reviewed; possible stabilization of nomenclature is envisaged. Proper typification of recognized species is necessary.
In France, these molds are used more specifically for their crucial role in the production of certain emblematic fermented products: cheeses with a rind in bloom Penicillium camemberti and blues P.
While some species have recently benefited from studies to better understand their structural genetic and functional phenotypic diversity eg, P. The questions posed by the empirical use of this species in the cheese field are twofold.
In the first place, one may wonder about the intraspecific diversity within this species that could be associated with a functional diversity. Thus, some strains may be more interesting than others in terms of growth or expression of their technological potential for applications either as a surface culture or as an anti-sticking agent.
This could therefore make it possible to set up tools for selecting strains of technological interest for the cheese industry. Secondly, our questions concern the genetic bases that can explain, on the one hand, the described absence of mycotoxin production in this species and, on the other hand, the adaptation to the cheese niche.
The approach envisaged for the thesis is as follows: Evaluation of the structural diversity of F. The latter will be identified by the genome sequence of the type of F. Physiological study: growth kinetics of representative strains of F. Study of functional diversity: the functional metabolic profiles of strains selected during the first part will be generated.
The technological advantages of the species F.
Genomic study: a comparative genomic study between the standard strain, the genome of which was obtained in the first part, and that of other available species will be carried out focusing on the biosynthetic pathways of the secondary metabolites eg mycotoxins.
Eventually, this genome can be used to reveal potential markers of adaptation to the cheese matrix.FUSARIUM CROWN ROT IN WHEAT AND A SURVEY OF FUSARIUM PSEUDOGRAMINEARUM AND F. CULMORUM IN THE PACIFIC NORTHWEST OF THE U.S.
