In vitro relative effects of lactobacilli isolates against biofilm formation and elastolytic activity of Pseudomonas aeruginosa PAO1

Biofilm formation*		Elastolytic activity *
Control	100%	Control	100%
L. fermentum ES.A.2	95%	L. fermentum K.C6.3.1D	63%
L. fermentum ES.F.115	93%	L. zeae Od.76	64%
L. fermentum ES.A.6a	88%	L. fermentum K.V9.3.2B	62%
L. fermentum ES.A.1a	88%	L. fermentum K.V9.3.2C	62%
L. paracasei ES.D.88	84%	L. fermentum K.C6.3.1E	53%

*Results are expressed as a percentage of biofilm formation or elastolytic activity related to control (P. aeruginosa PAO1 without lactobacilli). Only significantly active strains compared to control are displayed (LSD test, p < 0.05 for biofilm formation and p < 0.001 for elastolytic activity).
