Using the [https://2009.igem.org/Team:Newcastle/Project/Labwork/MoreProtocols#Recovery_of_cwlD_spores protocol] given to us, we performed lab experiments for the two non-germination spores, and concluded that the double-knockout mutant, sleB and cwlJ would be more ideal for our project as it had more colonies growing after treatment, and less colonies growing without treatment, as compared to the single knock-out mutant, cwlD.

Introduction

The main aim of our project is to sequester cadmium in the environment into the spores of our engineered B. subtilis, but what happens after the cadmium has been sequestered?

Do we attempt to retrieve the sequestered cadmium? Or, do we simply leave the sequestered cadmium in the spores of our engineered B. subtilis?

For our project, we have chosen the latter. We will not be attempting to retrieve the sequestered cadmium. However, then comes the question of, would there not be chances of the cadmium entering the environment again?

Our solution to this question would be to disable germination of the spores, thus retrieval of the sequestered cadmium becomes unnecessary, as the spores can persist intact for thousands of years.

In order to disable germination of the spores, we would require non-germinating spores, and we were fortunate enough that Prof. Anne Moir from Sheffield University kindly sent us two non-germination spores, namely cwlD, and sleB and cwlJ.

Using the protocol given to us, we performed lab experiments for the two non-germination spores, and concluded that the double-knockout mutant, sleB and cwlJ would be more ideal for our project as it had more colonies growing after treatment, and less colonies growing without treatment, as compared to the single knock-out mutant, cwlD.
