Effect of AHLs on biofilm formation ability of peanut-nodulating strains.

The biofilm formation ability of peanut-nodulating strains was determined after 72 h incubation in TY medium supplemented with various concentrations of 3OC10 AHL (A), 3OC12 AHL (B), and 3OC14 AHL (C). Values indicated by different letters are significantly different from each other according to Fisher’s LSD test (P < 0.05).
