1) The M9 agar plates were inoculated with C.freundii SBS 197, C.freundii NCIMB, E.coli J109, E.coli + sucrose hydrolase. The plates were left o/n 37ºC.
2) LB plates with 200 µl carbinicillin were prepared:
2* 50 µl MTZ (out of 50 mg/ml stock) 100 µg/ml+ 25 µg/ml IPTG
2*45 µl MTZ (out of 50 mg/ml stock) 90 µg/ml+ 25 µg/ml IPTG
5 µl NFT (out of 5 mg/ml stock) 1 µg/ml +25 µg/ml IPTG
1 µl NFT (out of 5 mg/ml stock) 0.2 µg/ml +25 µg/ml IPTG
50 µl DNBA (out of 50 mg/ml stock) 100 µg/ml +25 µg/ml IPTG
75 µl DNBA (out of 50 mg/ml stock) 150 µg/ml +25 µg/ml IPTG
Control +25 µg/ml IPTG
Control – IPTG
The MTZ plates were streaked with either BS control or BS nitred. All other plates were streaked with the four nitroreductase strains.

1)The M9 agar plates were examined. All strains grew on all plates even the no sugar ones.
The M9 agar plates were repeated by inoculating the remaining plates with the 4 strains present on the glucose plates (from 16th July 2012)
2)LB plates were examined:
Both BS control and BS nitred grew ( BS-contol much better) on the MTZ plates.
No difference between the strains was seen in the NFT, DNBA and control plates.
3)LB plates were prepared (200 µl carbinicillin)
2* 100 µg/ml MTZ + 25 µg/ml IPTG+80 µg/ml Xgal
110 µg/ml MTZ + 25 µg/ml IPTG+ 80 µg/ml Xgal
2* 120 µg/ml MTZ + 25 µg/ml IPTG+ 80 µg/ml Xgal
2* 130 µg/ml MTZ + 25 µg/ml IPTG+ 80 µg/ml Xgal
2* control + 25 µg/ml IPTG + 80 µg/ml Xgal
0.5 µg/ml NFT + 25 µg/ml IPTG+ 40 µg/ml Xgal
1 µg/ml NFT + 25 µg/ml IPTG+ 40 µg/ml Xgal
100 µg/ml DNBA + 25 µg/ml IPTG+ 40 µg/ml Xgal
150 µg/ml DNBA + 25 µg/ml IPTG+ 40 µg/ml Xgal
200 µg/ml DNBA + 25 µg/ml IPTG+ 40 µg/ml Xgal
4)Liquid cultures of BS-control, BS-nitred, nitred-6 and CFX-nitred were prepared.
Carbinicillin (5 µl) was added to LB (5 ml) and the bottles were inoculated with the four strains. These were left o/n at 37ºC with agitation.
