In this study, the effects of culture filtrates of lactic acid bacteria inhibit the growth of planktonic forms
of S. Typhimurium 1408 wild-type strain on biofilm formation and eradication in mutants with deletion
of a dam, and seqA genes of the said bacterium were investigated. As a result of the trials carried out on
polystyrene microtitre plates, it was determined that 6 lactic acid bacteria (Lactobacillus plantarum,
Lactobacillus sake, Pediococcus acidilactici, Bifidobacterium longum, Bifidobacterium bifidum, and
Pediococcus pentosaceous) used in the trials completely inhibited biofilm formation in these mutants at
optimum biofilm production times. In these experiments, culture filtrates were inoculated into biofilmproducing media together with the biofilm producer strain. In the eradication studies of biofilm structures,
culture filtrates were added to the medium after the biofilm structures matured. In eradication studies
carried out in this way, it was determined that the culture filtrates of lactic acid bacteria did not show any
biofilm eradication efficiency.
