Penicillin Acting on Bacteria

This short movie demostrates now a anit-bacterial ,Penicillin, acts on a gram negative cell E.Coli. When penicillin is used on e.coli the bacteria lengths and then it pops. Pencillin acts on the outer layer of the cell membrane. Penicillin allows the cell to lengthen but does not allow the cell to divide to make more new bacterial cells. Instead, the cell pops, killing the bacterial. This relates to the class because we have learnt that a bacteria's cell protects the nucleus inside the cell. However, if the cell wall dies then the bacteria will die to. http://www.hhmi.org/biointeractive/media/penicillin-lg.mov
