    Because of this inhibition the antibiotics are most effective when the bacteria are in the logarithmic phase of growth, where then they are synthesizing the cell wall. If the bacteria are in the stationary phase of growth, then there is no wall synthesizing in progress, and the antibiotics have much lower effect. [3]

    Penicillin and other β-lactam antibiotics act by inhibiting penicillin-binding proteins, which normally catalyze cross-linking of bacterial cell walls. Penicillin kills bacteria by inhibiting the completion of the synthesis of peptidoglycans, the structural component of the bacterial cell wall. It specifically inhibits the activity of enzymes ...
