  1. The diameter of the zone (mm) as a result of QS-associated virulence factors of the supernatant from A. hydrophila YJ-1 in mono- and co-culture with B. subtilis QSI-1 at 24 h after incubation, respectively, is shown. The experiments were conducted at least three times, and the data are expressed as mean values and standard deviation
