Heat Motility
The goal for our heat motility system is to obtain a higher concentration of silk in close proximity to the implant, which is achieved by immobilizing the silk producing bacteria once they are within some distance to the impant. The biological systems enabling this are the standard chemotaxis system and the DesK membrane fluidity sensor system (Link!). These systems have been modified and coupled to oneanother in order to stop B. Subtilis from moving when it is 37°C, and to make it swim when it is 25°C. In our model we simulate the behaviour of these systems and, if necessary, implement biologically plausible modifications to make it feasible.
