Biofilm formation of Pseudomonas aeruginosa P14 (panel a), Bacillus subtilis ATCC 6051 (panel b), Escherichia coli MG1655 (panel c) and Escherichia coli RS218 (panel d) in the presence of Pf1. Biofilm mass was assessed using crystal violet staining at 24 and 48 h time points. *Significantly increased compared to controlBack to article page
