Biosciences and Biotechnology Institute of Aix-Marseille
Our expertise is in regard to a lot of plant cultures: Arabidopsis thaliana, wheat, tomatoes, potatoes, pees, rice, ray-gras, salads, lucerne, carotts, sunflower, tobacco, quinoa, beech, hazel tree or oak.
A set of 15 measuring chambers with adjustable volumes (from a few liters to 1500 liters) are currently used for culture of plants in a fully controlled environment. They are hermetically closed modules in which several environmental parameters can be continuously and precisely regulated. A broad range of parameters can be manipulated : light (until 2000 µmol photons.m-2.s-1), temperature (from 1 to 50°C), relative humidity (from 20 to 80%), plant nutrition (quantitative and qualitative control), atmospheric gaseous composition (N2, CO2, O2, modification of stable isotope level (13C,..) throughout the growth cycle lasting up to several months. Moreover gaseous exchanges between plants and their environment (photosynthesis, respiration, transpiration...) can be continuously measured. A computerized controlling supervision ensures a safe functioning 24H/24.
In the phytotrons, the main parameters of environment - light, temperature, humidity and mineral nutrition - are controlled. They can be used for production of transformed plants and for plants screening. The total area (70 m2) provides culturing of 20 000 plants of Arabidopsis thaliana at the same time.
2 phytotrons in a controlled area are dedicated to experiments using radioactive isotopes with plants, microalgae or bacteria.
A QUALITY PROCESS AT YOUR SERVICE
A quality process is processed based on the ISO 9001v2000 standard for all its activities.
Experiments preparationThe definition of customer's needs is established and translated into technical requirements. The resulting forms for each experiment are then archived. For the external service (ANR, industries...) these are then completed by drafting the specifications and signing a contract of service.
Documentation The organization system is precisely described operationally in procedures, instructions, safety.
Monitoring and measurementsThe continuing of the experimental conditions of our facilities is provided by a control and operation system drived by the In Touch supervision software. This system is also implied into the monitoring of the facilities by emitting alarms which are sent to the permanently bound person 24H/24. The reliability of our facilities is reinforced by a computerized managing maintenance.
Traceability The supervision software ensures the traceability of experimental conditions by archiving the values of all the controlled parameters. The GMAO software ensures traceability of maintenance operations and apparatus calibration.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
