August 8

Testing for biofilms grown on 96-well plate and Erlenmeyer flasks with crystal violet
PCR of 16s
Transformation of I732019, I732005, J23119 from source plate in XL-10 gold.
Re-assembly of DDT gene using alternate method
GCMS of p450-degraded BPA samples Obtain experimental strain (biofilm-forming) MG-1655 E. coli and grow overnight in SOC

Results

Bacteria-incubated well remained cystal violet stained after several rinses, indicating the presence of a biofilm, in contrast to the clear control well.

96-well plate with XL-10 biofilm grown for two days, visualized with 1% crystal violet

Glass beads with XL-10 biofilm grown for two days, visualized with 1% crystal violet

Got successful amplification of 16s in LA River sample 9-9. In both gels, the controls had no bands and all other sample lanes had no bands.
BPA sample was too diluted for GCMS; must concentrate first.

August 9

Evaporate-centrifuge BPA sample to concentrate for GCMS
Create glycerol stocks of experimental E. coli strain MG-1655 for biofilm experiments
Did 16s sequencing experiments with a Master Mix.
Gibson assembly of pNT004 with PCRd insert
CPCR of more pNT002 colonies with VF2 and VR primers.
Retransform I732005 and I732019 with top ten cells. Plated on kan plates and amp plates since plasmid has resistance to both.

Results

I732019 and I732005 plates had no colonies.
Sequencing shows pNT003 and pNT002 colonies were self-ligated. But then what was the band on the cpcr gel?

August 10

Results

I732019 and I732005 plates had no colonies
pNT004 Gibson plates had no colonies
