Results after PCR from 17/09

Expected results

Results

The band for the third well is good. WE GOT IT !!!!!

Induction of BBa_K325909 and BBa_K1159001 with a solution of arabinose 1%, and a solution of IPTG 1 mM for T7-Nanoluc (should correspond to the effect of a constitutive promoter like T7). Under these conditions, light intensity of T7-nanoluc was 1,2 time higher than the BBa_K1159001.

Effect of the concentration of IPTG inducer to the light intensity of T7-nanoluc part. While the concentration of IPTG does not exceed 1 mM, the light intensity remains low.

Effect of the concentration of arabinose inducer to the light intensity of BBa_K1159001 part. Light intensity is linked to inducer concentration however over 1% of arabinose (final concentration), the intensity not rise anymore.

Liquid culture of bacteria transformed with pSB1C3-nanoluc (x5)

Liquid culture on 96 wells plate

When 0,6 < OD₆₀₀ < 0,8, induction with arabinose or IPTG Incubate 5h at 30°C; for BBa_K325909, measure the kinetic during the 5h of induction and take the maximum value
Add 50µL of NanoGlow substrate (Promega) for 50 uL of bacteria
Measure kinetic over 120 min and take maximum value for culture with BBa_K1159001 and T7-nanoluc

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

Colony - A6

Colony - A8

Colony - F1

All colonies exhibits same profile under same condition of light exposition and temperature. When the temperature is favorable for a bacterial development, the light activation of pDawn leading to the production of toxin is weak and do not impact a lot the growth of the population of bacteria. But at room temperature (RT°), the induction for protein synthesis is high enough to stop bacterial development

Two things lack to this experiment:

A longer time to measure if the population of bacteria could really decrease
A control at room temperature without light exposition to compare it evolution of OD 600 to the grey curve

Results

After the last Gibson reaction we have get red colonies that should correspond to bacteria transformed with pSB1C3-RFP (which should be impossible after the gel migration and purification). So we analyzed the content of the gel extraction and we saw that the tube only had linearized backbone. About pDawn III PCR 2, the migration of 5 µl from the gel extraction of PCR products have shown that there is not a high quantity of DNA material, not enough for a Gibson assembly…

Liquid cultures on plates from 08/09

Typical profile of colonies transformed with pDawn-HOKD under light exposition

Typical profile of colonies transformed with pDawn-CCDB under light exposition

Interesting profile with a diminution of the DO595 after it reach 0,6

Typical profile of colonies transformed with pDawn-Holin/Endolysin under light exposition

Continuous bacterial growth in spite of light exposure not expected

But some clones get the following profile

Very interesting profile, the DO600 fall down earlier than for all others clones
