Antibacterial Effects and Cell Morphological Changes in Sfaphylococcus aureus Subjected to Low Ethanol Concentrations
Ethanol in low concentrations (5–10% weight) affected aerobic growth (at 37°C) of two strains of Stuphylococcus aureus. Growth inhibition in laboratory media was observed with ethanol about 6–7% weight water activities (aw) of ∼0.97. This suggested that the ethanol antibacterial effect was not only...

| Sumario: | Ethanol in low concentrations (5–10% weight) affected aerobic growth (at 37°C) of two strains of Stuphylococcus aureus. Growth inhibition in laboratory media was observed with ethanol about 6–7% weight water activities (aw) of ∼0.97. This suggested that the ethanol antibacterial effect was not only from its aw lowering ability. Electron microscopy observations showed intense morphological modifications in cells in broth with 5% to 6.5% ethanol, and clearly indicated that cell wall changes of S. aureus was partly responsible for the antibacterial action of ethanol.
