Microorganisms have a natural capacity to attach to surfaces, to multiply and to embed themselves in a slimy matrix, forming biofilms. These allow complex interactions among different species and surfaces. There is significant evidence that bacterial growth in attached communities constituted the first form of life on the planet, and it is estimated that the majority of microbial activity on earth is resultant from biofilms, rather than microbes growing isolated in the form of planktonic cells…

Mechanism of Antimicrobial Resistance in Bacterial Biofilms

The resistance mechanisms of bacterial biofilms in food industry against antimicrobial agents are focused and include exopolysaccharide matrix, enzymes, heterogeneity, cellular persistence, metabolic activity, genetic adaptation, quorum sensing, stress responses, outer membrane structure and efflux pumps.

Antibiofilm Strategies in the Food Industry

This chapter discusses the main conventional and emergent strategies that have been employed to prevent bacterial adhesion to food processing surfaces and thus to efficiently maintain good hygiene throughout the food industries.

Biofilms: a biological antimicrobial resistance system

Interchange of information by the well-known quorum sensing alerts biofilm denizens of any event and induces a global response, which is facilitated by genetic interchange since distinct microorganisms are able to acquire enzymatic pathways from their neighbours which they could not otherwise.

Anti-adhesion and Anti-biofilm Potential of Organosilane Nanoparticles against Foodborne Pathogens

This study gives an insight to the efficacy of organosilanes based coatings against biofilm formation of foodborne pathogens, however, further studies are needed to better understand the impact of surface modification and the underlying mechanisms which are involved in this phenomenon.

Biofilms on Hospital Shower Hoses: Characterization and Implications for Nosocomial Infections

The results underscore the need to understand the microbiome of DW biofilms using metagenomic approaches and might lead to more robust management practices that minimize the risks associated with exposure to opportunistic pathogens in hospitals.

Investigating whether the sub-lethal dose of antibiotics can induce biofilm formation of P. aeruginosa to sub-MIC of antibiotics exhibited induction of biofilm in the presence of chlorhexidine found it to be possible.

Efficacy of disinfectants against Cronobacter biofilm on plastic surfaces

In this study, efficacy of benzalkonium chloride (BC), peroxyacetic acid (PAA) and chlorine dioxide (CD) against Cronobacter biofilm were evaluated on polystyrene surface. A pool of three strains of

Biofouling in food processing: biofilm or biotransfer potential?

The focus of this paper is on the diversity of forms in which the biotransfer potential may be presented, the aim being to recognize the limitations of the definition of the term biofilm and the problems which might arise as a result of this misnomer.

Bacterial biofilms: a common cause of persistent infections.

Improvements in understanding of the genetic and molecular basis of bacterial community behavior point to therapeutic targets that may provide a means for the control of biofilm infections.

Understanding antimicrobial activities of phytochemicals against multidrug resistant bacteria and biofilms.

The aim of this review is to cover the recent advances in phytochemical antibacterial activities and their mode of action, as well as to indicate current developments in their control of MDR bacteria and biofilms.
