Sporulation Tuning Team

Prof. Anne Moir from Sheffield University kindly sent us the spores of the genes cwlD and sleB/cwlJ

  • HC401 (FrpC2, cwlJ:: Kan, sleB-lacZ Ery R)
  • AM1877 (cwlD,Cm r, trp C2)

In the protocol given to us by Prof. Moir, there are two methods (Methods A and B), which can be used to recover the cwlD spores. However, neither give complete restoration of germination.

[Attach Prof. Moir's protocols]

Referring to Prof. Moir's protocols, Method A is a fast method which results in partial germination of approximately 0.1%. Method B on the other hand, is a slow method which involves stripping of the spore coat layers for improved germination of approximately 10% recovery. Due to the lack of time, the group decided to go with Method A.
