Abstract:L. monocytogenes 104035 and LO28 wild-type strains showed motility when gown at both 24 and 37°C although flagellin production was reduced during growth at 37°C. Both the wild-types and flagella minus mutants showed similar cells counts when attached over time on polystyrene microtiter plates and on stainless steel when gown at 24 and 37°C under static and shaking conditions. This suggests that flagella production in L. monocytogenes was not necessary for attachment and biofilm development. Scanning Electron Micrograph observations of L. monocytogenes gown on stainless steel chips for 24 hours and four days showed many cell aggregates formed on the surface, however no matrix of exopolymeric substances was seen.
