Four-species biofilm formation in the presence of cell-free supernatants
| Isolate replaced by its supernatant | Biofilm formationa | Relative biofilm formation (%) |
|---|---|---|
| None | 3.1 ± 0.18 | 100.0 |
| Microbacterium phyllosphaerae (2.04) | 2.8 ± 0.04 | 88.7 |
| Shewanella japonica (2.12) | 1.5 ± 0.28 | 46.8 |
| Dokdonia donghaensis (2.3) | 1.6 ± 0.23 | 51.9 |
| Acinetobacter lwoffii (2.34) | 3.0 ± 0.27 | 94.8 |

The biofilm biomass was quantified by staining with crystal violet and absorbance measurements. Values represent means ± standard errors for four replicates (biofilm OD600/planktonic OD600).
