Soil experiment

by Seong Koo

Plates observation and count of CFU:

• Strain 1696:
  • Dilution 1: 424 CFU
  • Dilution 0.1: 75 CFU
  • Dilution 0.01: 1 CFU

• Strain 1693:
  • Dilution 1: 524 CFU
  • Dilution 0.1: 35 CFU
  • Dilution 0.01: 0 CFU

• Strain 1320:
  • Dilution 1: 111 CFU
  • Dilution 0.1: 13 CFU
  • Dilution 0.01: 0 CFU

We take 1g of contaminated soil and treat it like yesterday to spread it on specific plates Incubation ON, 37°C

Interlab study: FACS

by Johan

We count 500 000 events Controls:

• Cells alones
• Cells transformed by BBa_J23101, BBa_J23106 and BBa_J23117

Our measurements: Cells transformed by

• BBa_J23101 + BBa_I13504
• BBa_J23106 + BBa_I13504
• BBa_J23117 + BBa_I13504

We uses cells in growth phase and stationary phase

Between each test, we do 2 washes with Cl- and 2 washes with H2O

Member present:

• Instructors: Alice
• Students: Coralie, Audrey, Pauline, Johan and Seong-Koo
