During aerobic respiration, the presence of oxygen and reactive oxygen species may affect cell membrane properties and, hence, the fitness and viability of LAB strains. Since respiration is a membrane‐based process, the modifications of cell membrane composition and, therefore, the reduction of membrane ... WebIt is found that ethanol has a stronger effect on the structural properties of the membranes. In particular, the bilayers become more fluid and permeable: ethanol molecules are able to penetrate through the membrane in typical timescales of ∼200 ns, whereas for methanol that timescale is considerably longer, at least of the order of microseconds.
