  • Title: Low concentrations of ethanol stimulate biofilm and pellicle formation in Pseudomonas aeruginosa.
    Author: Tashiro Y, Inagaki A, Ono K, Inaba T, Yawata Y, Uchiyama H, Nomura N.
    Journal: Biosci Biotechnol Biochem; 2014; 78(1):178-81. PubMed ID: 25036502.
    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.
