we have decided to attempt construction of a similar system. In the article pump was constructed by coating the inside of a tube with ''Serratia Marcesens''. This was done by washing a bacterial suspension through the tube at a speed, that allowed the cells to adhere to the surface. The flow also had the effect of alligning most of the bacteria, so their flagellae were facing downstream. When the induction of flow was stopped, the bacteria kept the solution flowing with their flagellae, in essens acting as a pump. Control was lent by altering the glucose concentration of the buffer solution. They were able to show a measurable force for several hours, before the cells became de-energized and died.<br><br>
