However, colonies were seen on the plates were no DNA was used for transformation. The most likely cayse of this is contamination whilst carrying out the electroporation. To check that the LB agar plates contained streptinomycin we picked a transformed colony and streaked it out on a freshly made LB agar plate containing streptinmycin. |

The principle of this protocol is that a culture is grown to a high O.D.<sub>600</sub>, this induces the stress pathways in ''B.subtilis'' and induces natural competence. These high cultures are diluted and then incubated with suitable concentrations of DNA. Transformed ''B.subtilis'' can then be plated out and grown on antibiotic resistant plates. Today ''B.subtilis'' were grown to an O.D.<sub>600</sub> of 2.0 and incubated with 40ng to 400ng of pDR110 DNA. | ||
