| - | {{Imperial/Box2|Working With ''B.subtilis''|Throughout this summer we worked with ''B.subtilis'' as a chassis. Although this chassis has great potential it is not commonly used and very few ''B.subtilis'' biobricks are available. We aimed to increase the accessibility of ''B.subtilis'' as a chassis. The major results of our work is summarised on this page.

| - | {{Imperial/Box1|''B.subtilis'' Biobricks|In order to pursue our project we had to design and build a variety of biobricks parts for ''B.subtilis''. These can be split up into the parts:
| + | |
| - | *'''Promoter and Ribosome Binding Sites (RBS)''' - These promoter and RBS combinations include a number of inducible and constitutive promoters combined with weak and strong ribosome binding sites.
| + | |
| - | *'''Coding Regions''' - These parts include specific coding regions concerned with our project such as biomaterials and in addition more general coding regions such as antibiotic resistance genes that can be used for selection markers.
| + | |
| - | *'''Integration Sites''' - As an alternative to maintaining genetic devices on extra-chromosomal plasmids we investigated the construction of parts to allow integration of genetic devices into the ''B.subtilis'' chromosome.

| - | {{Imperial/Box1|Transformation of ''B.subtilis''|In order to expand the use of ''B.subtilis'' as a potential chassis we investigated the different protocols used for the transformation of ''B.subtilis''. ''B.subtilis'' is used as the model for gram positive bacterium and have been extensively studied. A variety of protocols have been developed for the transformation of ''B.subtilis''. We investigated two different protocols, one relying upon natural competence of stressed ''B.subtilis'' and the using electroporation. The protocols and results were both fully documented to further the use of ''B.subtilis'' as a chassis.
