Architecture and Viability of the Biofilms Formed by Nine Listeria Strains on Various Hydrophobic and Hydrophilic Materials
Biofilms are a key factor in the persistence of Listeria in food processing plants, representing a potential source of foodstuff contamination. Nine Listeria strains (eight Listeria monocytogenes and
Effect of different conditions on Listeria monocytogenes biofilm formation and removal
Listeria monocytogenes poses a major risk for the safety of food products due to the ability to persist in food products and process line surfaces as biofilm. In this work, we investigated the L.
Chloride-accelerated Cu-Fenton chemistry for biofilm removal.
A simple approach was developed based on chloride-accelerated Fenton chemistry, where copper oxide nanoparticles facilitate efficient generation of reactive chlorine species for biofilm removal.
Initial adhesion of Listeria monocytogenes to solid surfaces under liquid flow.
Biofilm formation in bacterial pathogens of veterinary importance
The current knowledge of bacterial biofilms as well as studies performed on animal pathogens are reviewed, finding that biofilm formation by bacterial pathogens of veterinary importance has received relatively little attention.
Biofilm formation by Listeria monocytogenes. Resistance to industrial biocides and crossresponse caused by adaptation to benzalkonium chloride.
Estudio de las condiciones de formacion de biopeliculas de Listeria monocytogenes sobre su resistencia al envasado en atmosferas modificadas en mejillon vivo y cocido.
Comparative Evaluation of Different Sanitizers Against Listeria monocytogenes Biofilms on Major Food-Contact Surfaces
This study evaluated efficacies of four commonly used chemical sanitizers at practical concentrations against L. monocytogenes biofilms on major food-contact surfaces including stainless steel, low-density polyethylene (LDPE), polyvinyl chloride (PVC), polyester (PET), and rubber.


Influence of temperature on biofilm formation by Listeria monocytogenes on various food‐contact surfaces: relationship with motility and cell surface hydrophobicity
Aims:  To assess the ability of Listeria monocytogenes to form biofilm on different food‐contact surfaces with regard to different temperatures, cellular hydrophobicity and motility.
Biofilm formation by Salmonella spp. and Listeria monocytogenes on plastic surface
Aims:  To investigate the biofilm formation by 122 Salmonella spp. and 48 Listeria monocytogenes strains on a plastic surface.
Effect of Flagella on Initial Attachment of Listeria monocytogenes to Stainless Steel
A flagellin mutant of Listeria monocytogenes was found to attach to stainless steel at levels 10-fold lower than wild-type cells, even under conditions preventing active motility, suggesting that flagella per se facilitate the early stage of attachment.
Listeria monocytogenes LO28: Surface Physicochemical Properties and Ability To Form Biofilms at Different Temperatures and Growth Phases
The colonization of the two surfaces showed that the strain had a great capacity to colonize both surfaces whatever the incubation temperature, however, biofilm formation was faster on the hydrophilic substratum, and the surface physicochemical properties of the strain are correlated with adhesion and surface colonization.
Growth of Listeria monocytogenes as a Biofilm on Various Food-Processing Surfaces.
Biofilm growth of L. monocytogenes was sufficient to provide a substantial risk of this pathogen contaminating the food-processing plant environment if wet surfaces are not maintained in a sanitary condition.
Effect of Nutrients on Biofilm Formation by Listeria monocytogenes on Stainless Steel.
Replacement of amino acids in MWB with tryptone initially enhanced biofilm development, but the effect was not significant after 12 days of incubation, and of five carbohydrates tested, mannose and trehalose enhanced biofilms development.
Characterization of physicochemical forces involved in adhesion of Listeria monocytogenes to surfaces
Physicochemical characterization of Listeria monocytogenes by various methods indicates that this microorganism is hydrophilic, and the interfacial free energy of adhesion of L. monocyTogenes Scott A estimated for polypropylene and rubber was lower than that for glass and stainless steel, however, these theoretical implications could not be correlated with the attachment capabilities.
Relationship of cell surface charge and hydrophobicity to strength of attachment of bacteria to cantaloupe rind.
Initial bacterial attachment was highest for individual strains of E. coli and lowest for L. monocytogenes, but Salmonella exhibited the strongest attachment on days 0, 3, and 7 and when mixed-genus cocktails were used, the relative degrees of attachment of the three genera ware altered.
