-Identification and biotechnological characterization of lactic acid bacteria.
-Development of qPCR methods for food pathogen detection.
-Validation of sanitation procedures in the food industry by detection of viable by qPCR (vqPCR).

Key words:
PCR, pathogens, detection, identification, exopolysaccharides, vitamins, antimicrobials, functional foods
Summary:
-Quantitative detection by qPCR of foodborne pathogens (bacteria and enteric viruses), viable / infectious forms, altering bacteria of meat products and ochratoxigenic fungi.
-Validation and adaptation to the routine food analysis of PCR-based detection methods.
-Efficiency of processes applied in food industry (eg high pressures, active containers, ultrasound, etc.) for the elimination of pathogens (viruses and bacteria).
-Identification and typing by PCR-based techniques of new strains of lactic bacteria.
-Study of the biotechnological potential of lactic bacteria isolated from fermented products (production of exopolysaccharides, vitamins, antimicrobial activity ...) and its application in functional foods.
