Transformation ECE188, 189, 190 into E.coli

- Results : only our control plate grew!!

- Maybe we did not add enough DNA, or there is another problem. We will e mail the guy from Bacillus center before trying again, because we don't have enough DNA.

Plasmid miniprep ECE 151 (x2), ECE 153, ECE 166

  • Nanodrop results :
260/280 ng/μL
ECE 151 (3) 1.79 86.8
ECE 151 1.88 106.3
ECE 153 1.80 32.2
ECE 166 1.87 36.2


Xylose Induction with ECE 153

- 4 Tubes

- No fluorescence! We have to think about the transformation of integration vectors into Bacillus.


Glycerol Stock Transformation

- Spin down cells (competent) from 5/8 and 13/8 stocks

- Remove liquid, resuspend in Medium B

- Incubate for 60 mins at 37°C

- Add ECE 166 into tubes

- Incubate for 30 mins at 37°C

- Plate out on CM 5 plates

- 4 plates

  • 771 (5/8) + ECE 166
  • 771 (5/8) Control
  • 771 (13/8) + ECE 166
  • 771 (13/8) Control


Transforming ECE 188, 189, 190 (3rd try)

- 2 tubes of chemically competent top 10

- Spin down, remove liquid

- Resuspend cells in 100μL of CaCl2 50mM

- 4 tubes with 50μL of cells

  • ECE 190 (all)
  • ECE 189 (all)
  • ECE 188 (all)
  • PUC 9 (5μL) [ Control ]

- Ice for 30 mins

- 42°C for 2 mins

- Ice for 2 mins

- Incubate at 37°C for 2 hours

- Plate out on Amp 100 (Neat)
