| Abstract: | Biofilms are communities of surface-attached microbial cells that resist environmental stresses. In this study, we found that low concentrations of ethanol increase biofilm formation in Pseudomonas aeruginosa PAO1 but not in a mutant of it lacking both Psl and Pel exopolysaccharides. Low concentrations of ethanol also increased pellicle formation at the air–liquid interface. |
