''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. | + | {{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''.

| - | We characterised the growth rate of ''B.subtilis'' in LB media at 37<sup>o</sup>C. This curve provides useful information when inducing protein synthesis in ''B.subtilis'' and when characterising parts such as promoters. In addition to collecting this growth curve information, we modeled the growth rate of ''B.subtilis'' which can be found by [https://2008.igem.org/Team:Imperial_College/Growth_Curve clicking this link].| | + | We characterised the growth rate of ''B. subtilis'' in LB media at 37<sup>o</sup>C.
