Wrinkly Spreader biofilm characteristics in modified microcosms.

Treatment		Relative microcosm growth (G/G _R)	Relative biofilm strength (S/S _R)	Relative attachment (A/A _R)
Standard KB^∗ microcosm	No oil, 1x nutrients	1.000 ± 0.051^a	1.000 ± 0.167^a	1.000 ± 0.081^a

With oil overlays	10 mm	0.451 ± 0.026^b	0.153 ± 0.024^b	0.311 ± 0.026^b
	20 mm	0.381 ± 0.017^b	0.226 ± 0.035^b	0.394 ± 0.030^b
	40 mm	0.247 ± 0.011^c	0.194 ± 0.046^b	0.375 ± 0.044^b

With reduced-nutrient levels	0.1x	0.408 ± 0.009^b	0.194 ± 0.021^b	0.535 ± 0.106^b
With reduced-nutrient levels	0.01x	0.117 ± 0.002^c	0.113 ± 0.016^b	0.343 ± 0.073^b

Altered A-L interface shapes	Concave	1.000 ± 0.026^∗	1.000 ± 0.144^∗	1.000 ± 0.056^∗
Altered A-L interface shapes	Convex	0.918 ± 0.027	0.545 ± 0.166	0.577 ± 0.089

Microcosms were incubated for 3 days before assay. Relative means ± SE are shown (n = 6). The reference microcosms for the oil-overlay and reduced-nutrient assays were provided by the standard KB^∗ microcosms. The reference microcosms for the altered A-L interface shape assays were provided by the concave microcosms. Comparisons of relative means were by assay and treatment. For the oil-overlay and reduced-nutrient experiments, means not linked by the same letter are significantly different (TK-HSD, α = 0.05). For the A-L interface shape experiment, means which are significantly different are indicated by ∗ (t-test, p ≤ 0.05).
