TOPIC 1

MONITORING FOOD QUALITY, SELECTION AND TRACEABILITY

Key words :
lactobacillus, yeast, Geotrichum candidum, ciguatoxins, food and feed, cheese, fish

The Laboratory of Food Microbiology works on the following:

The selection of microorganisms for cheese-making
The roll out of yeast and lactobacillus traceability, with a focus on probiotic yeast and lactobacillus, in food products
The study and quality control of tropical fish potential carriers of ciguatera-toxins causing CFP, ciguatera fish poisoning, (the only lab in Europe dedicated to this specialised area)
   
The Teams
Laboratoire de Microbiologie Alimentaire E.A 3213 U.S.C INRA (Laboratory of food microbiology)
A total staff of 20 to 25 people (5 research teachers, 3 technical and service personnel, 3 seconded researchers from companies, 8 research students (post-doctorate students, doctorate candidates, European contracts, and students advanced masters), 6 other interns
   
Equipments
Polymerase Chain Reaction (PCR) Amplifier; Pulsed Field Gel Electrophoresis (PFGE) equipment; Temperature Gradient Gel Electrophoresis (TGGE) equipment; High Performance Liquid Chromatography (HPLC), epifluorescent microscope
   
Methods
Methods of molecular biology applied to microscopic fungi (eucaryotes) and bacteria:
PFGE, Random Amplified Polymorphic DNA (RAPD-PCR), Random Amplified Microsatellites (RAM-PCR) or Inter-Single Sequence Repeats (ISSR), Internal Transcribed Spacer (ITS), Restriction Fragment Length Polymorphism (RFLP)
Chromatography techniques

Recent research on the traceability of yeast in food products is another area of expertise of the Laboratory of Food Microbiology (detailed in the 'Microorganism characterisation and selection for cheese-making' file).
