1. For each E.coli strain, bacterial colony is inoculate to 6 ml LB medium containing appropriate antibiotic and grow overnight in normal 37°C incubator.

2. Incubate for 16 hours.

3. Take 60 μl of bacterial culture to refresh in 6 ml LB containing containing appropriate antibiotic and different concentration of tyrosine.

4. Incubate the refreshed cell culture in anaerobic incubator at 37°C.

5. Samples are collected in the 24- and 48- hour, after the initiation of the anaerobic 37°C incubation.

Sample collection:

1. 250 μl of samples are collected at the 2 particular times stated above.

2. The positive control is prepared by collecting 225 μl of negative control (Wild-type strain) culture with 25 μl of 500 μM, 250 μM and 50 μM of p-Coumaric acid in LB to create a bacterial culture with p-Coumaric acid concentration of 50 μM, 25 μM and 5 μM.

Sample Extraction:

1. Directly after sample collection, the samples are lysed with 25 μl of Lysis buffer (PD2) and neutralized with 43.5 μl neutralization buffer (PD3). (Thermo plasmid MiniPrep)

2. All samples are acidified in 12.5 μl concentrated acetic acid and vortexed.

3. Samples are then induced with 50 μl n-octanol (the organic phase in two-phase extraction).

4. Vortexing and centrifugation (>12000 g, 1 min) followed and the upper organic phase is collected for measurement.

Measurement:

1. The absorbance in the UV-spectrum (190 nm-350 nm) of the octanol extracts is measured in a spectrophotometer (NanoDrop).

2. The spectrophotometer blanked by pure n-octanol.

3. All measurements are done on 2 μl of extractant.

4. Absorbance measurements are done in the same way on the standards of p-Coumaric acid in octanol prepared from solid p-Coumaric acid.
