Inhibition of biofilm formation by cell-free extracts. Data are expressed as mean percentage in respect to biofilm growth control in fresh BHI broth. Black bars = control; grey tone bars = untreated cell-free extract (NT); slanted lines bars = pH neutralized cell-free extract (pH); dotted bars = heat inactivated cell-free extract (TH). * P ≤ 0.05; ** P ≤ 0.01; *** P ≤ 0.001
