Eric F. and Melody
Biofilm Growth Protocol Day 5+ (100814 E + M aka Colourful Contaminate + Round Bottomed Failure)
- Performed resolubilization
- Used 150uL 95% ethanol instead of 200uL
- The Round Bottomed Failure had more 0.1% crystal violet added
- Crystal Violet was allowed to resolubilize for too long (30 minutes +)
- No readings were taken - all information was scrapped
- Plates discarded
Biofilm Growth Protocol Day 5+ (100816 E + M aka Shades of Purple and Eric's Ethanol Shame)
- Performed first day 4 plate reading

- Only useful information was confirming the correct orientation of plates in the reader
- Plates discarded
Biofilm Growth Protocol Day 4 (100823 E + M aka Eric's Pride 1 and Melody's Shame 1)
- Stained with 0.1% crystal violet, left to dry overnight in biosafety cabinet
Biofilm Growth Protocol Day 3 (100824 E + M aka Eric's Pride 2 and Melody's Shame 2)
- Performed washings with multi-channel pippeteman using unautoclaved pippete tips
- Left overnight in biosafety cabinet
QS Track
- A film of bacteria grew again on chloramphenicol plates.
- Do not know why.
- Picked colonies from agrAC (natural) + J23100, agrAC (natural) + B0014, agrAC (natural), and agr AC (distribution) + J23100.
- Very difficult to do. Probably obtained many colonies at the same time.

PCR Tubes: 1,4,5,8,11,14,15,his,n1,n2,n3,n4,n5,W(H2O control)
- Pick colony from respective plate and place in respective tubes
PCR Cycles:
- 98C @ 3min
- Cycle 27x:
- 98C @ 10 sec
- 72C @ 30 sec
- 72C @ 40 sec
- 72C @ 10 min
- 10C @ hold
- Ran gel for 1 hour. 80 V 0.5X TBE 1.3% agaorse. Two small 8-lane gel boxes. Also included 1 kb NEB ladders.
- Results show many bands. Apparent weak bank/smudge of DNA above 2 kb region. Probably means many different plasmids present. The film probably has low antibiotic concentration.
- Therefore, streaked some bacteria from each of the agrAC plates in the hopes of finding single colonies. Incubate at 37 °C.
- Made DH5alpha O/N for competent cell making. Unfortunately, had to use Finlay lab incubator on the 3rd floor, which runs at 37 °C and 200 rpm.
