Table 1:

Experimentally measured CACs of naturally occurring AHLs.

AHL	CACs (μM)
	Light scattering		Surface tension
	Water^a	LB medium^b	Water^c
C4-AHL	No aggregation
3-oxo-C8-AHL	1920 ± 150	2020 ± 20	2170 ± 250
3-oxo-C12-AHL	88 ± 20	78 ± 17	97 ± 11
C12-AHL	3.7 ± 0.3	3.8 ± 0.4	4.0 ± 0.2
C16 AHL	0.12 ± 0.14	0.09 ± 0.02	0.16 ± 0.04^**

Experiments performed at ^a30 °C in deionized water, ^b37 °C in LB medium, and ^croom temperature (RT) in deionized water. All experiments contained 1% DMSO in the aqueous phase. The CAC values reported are the averages and standard deviations of three replicates.
