Viability of S. aureus and C. albicans in mixed culture in presence of benzalkonium chloride with concentrations 0, 0.25, 0.5, 1, 4, and 8 µg/mL separately and in combination with (−)-myrtenol and (+)-myrtenol at a concentration of 256 µg/mL. The viability of bacterial and fungal cells was assessed after 24 h growth in culture liquid and after 48 for adherent cells. The viable cells were counted after a series of ten-fold dilutions followed by plating on selective media for differentiation of S. aureus and C. albicans.
