Aim – We would like to determine if our curli producing BBa_K729018 is capable of producing shear resistant biofilms.
1) Cells are grown overnight in 10ml of LB media at 37˚C, 200rpm.
- a) BBa_K729006
- b) W3110 Control
2) Shake flasks are inoculated with 5 ml of cells into LB media (100ml)
- a) Shake flasks contain pre-sterilised polycarbonate discs
3) Shake flasks are run at 37˚C, 200rpm, for 7 hours.
4) Shake flasks are run at 30˚C, 50rpm, for 14 hours.
5) PC discs are removed from flasks, dried, and stained with crystal violet.
6) Discs are sheared with the small scale shear device, using water as the buffer. Rotaion speed varies from 50rpm to 700rpm.
7)
Conclusion - Our transformed cells are producing shear resistant biofilm, with double the shear resistance of untransformed biofilms, indicating that our BioBrick is working as intended and is capable of producing shear resistant curliated biofilms.
