“…Since stainless steel (SS) is a widely used material in the food industry, a lot of effort has been devoted to the research of SS modification. The environmental factors in food processing environments and the properties of stainless steel enabling the attachment of bacterial cells on the surface of SS have been intensively reviewed [107]. Silver ions are known to interact with thiol groups of cysteine, resulting in the disruption of the permeability of membranes, and the release of a reactive oxygen species causing oxidative stress.…”

This review deals with microbial adhesion to metal-based surfaces and the subsequent biofilm formation, showing that both processes are a serious problem in the food industry, where pathogenic microorganisms released from the biofilm structure may pollute food and related material during their production. Biofilm exhibits an increased resistance toward sanitizers and disinfectants, which complicates the removal or inactivation of microorganisms in these products. In the existing traditional techniques and modern approaches for clean-in-place, electrochemical biofilm control offers promising technology, where surface properties or the reactions taking place on the surface are controlled to delay or prevent cell attachment or to remove microbial cells from the surface. In this overview, biofilm characterization, the classification of bacteria-forming biofilms, the influence of environmental conditions for bacterial attachment to material surfaces, and the evaluation of the role of biofilm morphology are described in detail. Health aspects, biofilm control methods in the food industry, and conventional approaches to biofilm removal are included as well, in order to consider the possibilities and limitations of various electrochemical approaches to biofilm control with respect to potential applications in the food industry.

“…The SRB bacteria get their energy from reducing sulfate in humans and animals' gastrointestinal tracts (mouth and intestines). These microorganisms are found everywhere in the environment and are scattered in the water, air, and soil (Dula et al, 2021). Numerous studies have shown that bacteria in the oral environment infect the tissue around the tooth and cause inflammation.…”

Sulfate-Reducing Bacteria (SRB) are a heterogeneous group of oral microflorae that cause dental caries, destructive periodontal infections, and biofilms on fixed orthodontic appliances. Plant extracts as a source of antibacterial components may have acceptable activity against SRB strains and their biofilm development. Our study aimed at determining the antibiofilm, antimicrobial efficacy, and cytotoxicity of Iran's endemic plants against pathogenic SRB. Plantago ovata, Terminalia chebula, Eugenia caryophyllata, and Aloe vera extracts were prepared according to standard methods. Patients and orthodontic appliances samples were collected, and SRB strains were isolated using standard tests and 16S rRNA analysis. The extracts' antimicrobial, antibiofilm activity, and cytotoxicity were determined using dilution broth micro, crystal violet staining, and MTT method, respectively. Biofilm involved gene expression of strains determined using Real-time PCR. Three SRB isolates harboring target genes were identified using 16S rDNA that showed a more than 90% of similarity to Desulfomicrobium orale spp. All investigated extracts showed good activity against SRB isolates. T. chebula, E. caryophyllata, and A. vera showed promising antibiofilm activity, and their subMIC concentrations downregulated biofilm-forming related genes in all isolates. T. Chebula had the lowest cytotoxicity, followed by E. caryophyllata and A. vera. T. Chebula also showed the best average selectivity index (SI) of 17.9, followed by E. caryophyllata (12.52). Extracts investigated in the present study had good antibacterial and antibiofilm activity against isolated sulfate-reducing bacteria isolated from patients' orthodontic appliances. Most of these extracts may be potential candidates for the development of antibacterial drugs.

“…Bacterial biofilms on the surfaces of processed foods are critical sources of contamination and are resistant to cleaning and disinfection procedures. Moreover, the presence of bacterial biofilms in food processing environments puts human health at risk (Dula et al 2021).

Staphylococcus aureus is one of the main aetiological agents causing food‐borne diseases. Some strains produce enterotoxins responsible for food poisoning. In addition, they can form biofilms on several surfaces such as plastics, glass and stainless steel making it difficult to eliminate them. The present study evaluated, for the first time, the antibacterial and antibiofilm activities of the synthetic compound LMM6 against S. aureus. The minimum inhibitory concentration was 0·97, 1·95 and 1·95 μg ml−1 against S. aureus ATCC 25923, S. aureus 629/94 and S. aureus FRI S‐6, respectively. The time‐kill curves showed that 96 h treatment with LMM6 reduced approximately 4 log CFU per ml at all tested concentrations. Furthermore, LMM6 reduced S. aureus preformed biofilm by approximately 1 log CFU per cm2. During biofilm formation, a reduction of approximately 4 log CFU per cm2 was observed. LMM6 also reduced biofilm biomass during (~60%) and after biofilm formation (~25 to 45%), as shown by the crystal violet assay. Based on these results, we conclude that LMM6 exhibits antibacterial and antibiofilm activity and may be an innovative synthetic molecule for controlling S. aureus.
