Detection moleculaire des bacteries lactiques productrices d'amines biogenes

Abstract

Au cours des dernières décennies, une plus grande attention est portée à la sécurité alimentaire afin de protéger la santé humaine que ce soit sur les contaminants chimiques, contaminants physiques ou contaminants d¿origine biologique. Le secteur des aliments fermentés nécessite une attention particulière en raison de la complexité de leur processus de transformation biotechnologique. La recherche de contaminants d¿origine naturelle et biologique tels que les amines biogènes est particulièrement importante, car certaines de ces molécules, notamment l¿histamine, sont dangereuses pour l¿homme si la dose ingérée est trop élevée. L¿objectif de cette étude consiste en la détéction des souches de bactéries lactiques spécifiques (Lactobacillus, Lactococcus et Enterococcus) productrices d¿amines biogènes ainsi que la recherche des gènes codant pour les enzymes impliquées dans la production de deux amines biogènes (Tyramine, Histamine) avec des amorces spécifiques de chaque amine biogène étudié par PCR ainsi qu¿une étude sur milieu de culture spécifique. Les bactéries lactiques ont notamment été identifiées à partir_de l¿ARNr16S.
