If we do quiescence, will have to be in e coli with bacillus as a side project. Have to get over IP issues with ucam + e coli. Implementation in ecoli will be fairly easy as it is a working system - all we need to do is brick it, and get it working.

Literally no documentation of h-ns and rcd in bacillus.

If we do quiescence, will have to be in e coli with bacillus as a side project. Have to get over IP issues with ucam + e coli. Implementation in ecoli will be fairly easy as it is a working system - all we need to do is brick it, and get it working.

  • Has to be done in E.Coli, will not work in non Coliform bacteria such as Bacilli.
  • Switch on cell division would be very useful, however there are IP issues which must be discussed with David Summers.
  • Another constraint is that liquid broth not agar must be used.
  • Nobody has looked at it from a microfluidics point of view.
  • When done before, the lambda phage takes 3 hours to initiate quiescence after the temperature change.
  • The Lambda phage is the most stable to have an off switch, it does not express itself when needed (?)
  • The RNA has a very long half life, it would be hard to strip away the system and put it under a new promotor, but, if possible would be extremely useful
