3.1.2. Detergent-Like Membrane Disruption<br />

Microbial membrane disruption can occur either by formation <strong>of</strong> pores which increase<br />

the membrane permeability to ions <strong>and</strong> larger molecules, or by hydrolysis <strong>of</strong> membrane<br />

phospholipids. Most <strong>of</strong> these bactericidal agents are peptides or peptide-based molecules that<br />

have been either isolated from natural sources or synthetically designed. Lipophilic<br />

flavonoids <strong>and</strong> terpenoids may also disrupt the microbial membranes.
