    Measure of osmotic pressure influence


      Preparation of different media : 0M - 0,01M - 0,05M - 0,1M – 0,5M
      1. x (µL) Sucrose 1M
      2. 2,5mL media M63
      3. 50µL of glucose
      4. Complet with steril water until 5mL

      Incubate during 24 h at the temperature 28°C and the shaking speed of 100rpm

      Measure of the fluorescence : input wavelenght 490 nm, output one 510 nm.

      Measure of the biomass(absorbance 600 nm): Dilute 250 µL of culture in 750 µL of water.
      Make the blank with 0,5mL of media M63 and 0,5mL of steril water
