Biofilm eradication assay. Log₁₀ bfu/peg biofilm viable counts and percent reduction of pre-established P. aeruginosa (PAO1) biofilms challenged with 100 μL of 3-day supernatant of marine isolate KS8 in the CBD (24 h at 37 °C and 95% relative humidity at 150 rpm). Differences in log₁₀(bfu/peg) were considered significant when p < 0.05 (* p < 0.05, ** p < 0.01, *** p < 0.001) according to the non-parametric Kruskal Wallis test with Dunn’s Multiple Comparison Test. Values for the percent reduction in biomass absorbance are also included.

	Biofilm Formation		Biofilm Eradication
	Log10 bfu/peg	Δ (Log10 bfu/peg) and % Reduction	Log10 bfu/peg	Δ (Log10 bfu/peg) and % Reduction
Untreated PAO1	7.30		7.52
KS8	6.34	−0.96	5.52	−2.00 (***)
		(−89.04%)		(−99.00%)
