Result from yesterday transformation

Vector Antibiotic Quantity of cells added number of colonies
ECE166 Cm5 200μL 0 : problem!!!
ECE166 Cm5 100μL 2
ECE166 Cm5 50μL 1
ECE166 Cm10 100μL 0 : no resistance to Cm10!
ECE166 (spin) Cm5 100μL a lot, confluent
ECE166 (spin) Cm10 100μL 0
ECE166 (glycerol + spin) Cm5 100μL about 150, very small
ECE166 (spin) Cm10 100μL 0
ECE153 Spc50 200μL 21 + a lot of confluent colonies
ECE153 Spc50 100μL 7 + confluent (a few)
ECE153 Spc50 50μL 4
ECE153 (spin) Spc50 100μL 25 + about 200 (small and almost confluent)
No DNA Cm5 100μL 0
No DNA Cm10 100μL 0
No DNA Spc50 100μL about 12, maybe more : problem!!!!!

Result for test of ECE112 transformation

On Cm5 plates, we have some colonies for each strains, on Cm5 + Spc 100 plates, no colonies on each plates. This result seems good, however, we forgot to make a control. Since, we had some colonies on control plates, it is possible that our bacillus are resistant to Cm5, even if they are not transformed. We addded some control colonies.

Control with erythromycin

- Prepare erythromycin, stock 5mg/mL : 0.05g in 10mL of SDW

- Prepare plates : add 20μL of Ery (5mg/mL) into 200mL of agar (final concentration : 0.5μg/mL)

- Do several spots on each plate

Plate Colonies added from
1 ECE166 + 100μL of cells (2 different plates)
2 ECE153 + 100μL of cells (2 different plates)
3 ECE166 (from glycerol stock)
4 Control (from a plate of IA771 without antibiotic)
5 IA771 + ECE112 (05/08)
6 IA771 + ECE166 (05/08)

Amylase production screening

  • Prepare agar plate with starch

- Starch : 1g of starch in 10mL of SDW

- Add 2mL of Starch solution into 200mL of agar, mix

-Inoculate on different plates : 1A1 +ECE112 (plate from 05/08), IA751 + ECE112 (plate from 05/08) and IA771 + ECE153

New stocks

- Take 1mL from LB stock oh ECE171 (from 07/08) and put it into 99mL of LB
