| Biofilm formation results in medical threats or economic losses and is therefore a major concern in a variety of domains. In two-species biofilms of marine bacteria grown under dynamic conditions, Pseudoalteromonas sp. strain 3J6 formed mixed biofilms with Bacillus sp. strain 4J6 but was largely predominant over Paracoccus sp. strain 4M6 and Vibrio sp. strain D01. The supernatant of Pseudoalteromonas sp. 3J6 liquid culture (SN3J6) was devoid of antibacterial activity against free-living Paracoccus sp. 4M6 and Vibrio sp. D01 cells, but it impaired their ability to grow as single-species biofilms and led to higher percentages of nonviable cells in 48-h biofilms. Antibiofilm molecules of SN3J6 were able to coat the glass surfaces used to grow biofilms and... |

| Bacterial biofilms, frequently in association with algae, protozoa and fungi, are found on all submerged structures in the marine environment. Biofilms are responsible for a range of surface‐associated and diffusible signals, which may moderate the settling behaviour of cells, spores and larvae. Thus, marine microorganisms are a new source of bioactive compounds, which enhance or inhibit the settlement of organisms. |

| Marine organisms represent a rather unexplored source of new activity and biological functions of molecules for biotechnologies. The research in chemical ecology of the marine environment leads to looking at metabolites of recognition or defence produced by these models. Marine bacteria belonging to the Pseudoalteromonas genus of the Gammaproteobacteria class are often found in association with marine eukaryotes, and their ability to produce a variety of biological activities attracted a particular attention. The marine Pseudoalteromonas sp. 3J6 and D41 were selected for their capacity to inhibit the biofilm formation of other bacteria. The study of antibiofilm metabolites synthesised by marine bacteria 3J6 and D41 biofilms can lead to the development of... |
