Its mode of action on membrane integrity was confirmed by release of extracellular ATP (1.42 and 1.33 pg/mL), loss of 260-nm absorbing materials (4.36 and 4.19 optical density), leakage of potassium ions (950 and 1000 mmol/L) and increase in relative electrical conductivity (12.6 and 10.5%) against food-borne pathogenic bacteria <em>L. monocytogenes</em> and <em>E. coli</em>, respectively. These findings propose that <em>C. bonducella</em> oil compromised its mode of action on membrane integrity, suggesting its enormous food and pharmacological potential.</p> ER -
