Knockout of pseC and legC decreases biofilm formation of T. forsythia ATCC 43037 and T. forsythia UB4 cells, respectively. (A) Biofilm formation in T. forsythia ATCC 43037 wild-type compared to ATCC 43037 ΔpseC and the complemented strain ATCC 43037 ΔpseCcomp. (B) Biofilm formation in T. forsythia UB4 wild-type compared to UB4 ΔlegC and the complemented strain T. forsythia UB4 ΔlegCcomp. Data represent mean values ± SD of at least four independent experiments with four replicates each and were analyzed by the unpaired Student's t-test. Asterisks indicate significant differences (**P < 0.01).
