Culture liquid: pDawn – H/E 20 mL LB + 20 µL Kan, without light;

Measurement of the OD600 of liquid culture

When the OD600 has reached 0.6 or more, the volume of culture has been divided into 3 erlenmeyers:

  • 1 erlenmeyer without light exposition, 37°C
  • 1 erlenmeyer with light exposition, 37°C
  • 1 erlenmeyer with light exposition, room temperature

Measurement of the OD600 every hour
3 culture on 5have shown a bacterial development

Results

Graph-HE.png


Bacteria expressing pDawn-HE were prepared in a pre-culture until DO600 reached a value between 0,6 and 0,8. Then, one condition was illuminated with white-light and incubated at 37°C, another one was kept in the dark and incubated at 37°C and the last condition was illuminated with white-light and incubated at room temperature. The value of DO was taken regularly to observe the kinetic of growth under each condition.

In absence of light, and at 37°C, bacteria growth was normal but light illumination was enough to slow-down the growth of bacteria. Incubation at room temperature with white-light illumination allowed better folding of HE and had a stronger effect on the growth of bacteria.
