Figure 6. Ethanol and the quorum sensing molecule tryptophol induce flocculation in the feral EM93 strain.

Figure 6

Cultures of S. cerevisiae EM93 were grown in standard rich medium (YPD) with or without the addition of various known quorum sensing molecules and analogues thereof. A. Measurement of flocculation. Error bars represent standard deviation, asterisks indicate statistically significant differences from the control (i.e. no addition of any agent) (α = 0.05). B. Increasing flocculation of EM93 cultures observed with increasing concentration of ethanol.
