Fig. 6From: Bacterial signals N-acyl homoserine lactones induce the changes of morphology and ethanol tolerance in Saccharomyces cerevisiae Ethanol tolerance of S. cerevisiae induced by AHLs. Aliquots (4 μL) of tenfold serial dilution of the S. cerevisiae resting cells were spotted onto YPD plates, YPD plates plus 6% (8%) ethanol, and YPD plates supplemented with 6% (8%) ethanol and 2 μM AHLs, respectively, and grown at 30 °C for 10 days. The left-to-right colonies represented the tenfold gradient dilution of 100, 10−1, 10−2, and 10−3, respectivelyBack to article page
