Surface tension and associated standard deviations of P. fluorescens DSS73’s growth in estuarine water with or without nutrients. All experiments were performed in triplicate.

Tested Medium	Surface Tension (mN·m 1)		Amphisin Production
	Before Growth	After Growth
DMB	69.3 ± 0.9	30.4 ± 0.5	+
Estuarine water without nutrient	60.9 ± 0.5	32.8 ± 0.2	+
Estuarine water with nutrients		29.8 ± 0.6	+
