Many bacteria are able to attach to and colonise environmental surfaces by producing a biofilm, which allows the organisms to persist in the environment and resist desiccation, UV light and treatment with antimicrobials and sanitising agents. Biofilms are formed when microbes attach to a solid support and to each other…

New research underscores the critical need for innovative solutions to combat biofilm formation on food-contact surfaces, which poses a major risk to public health and food quality.

[…] and in this way further the development and spreading of antibiotic resistance in bacteria. Resistance mechanisms in bacteria can be divided into natural mechanisms (permeability barrier and biofilm formation) and acquired resistance mechanisms (mutations, acquisition of genes, impermeability, target site alterations, enzymatic transformation and efflux pumps). This article will…

[…] found in coastal waters, up the food chain. Researchers from the University of Portsmouth tested a theory that MPs covered in a layer of microbes, (called a biofilm) were more likely to be ingested by oysters than clean micro plastics. Despite the experiment being carried out on oysters under…

[…] much more tolerant to disinfectants than bacteria in solution. Biofilms are communities of surface adhered bacteria that are embedded in a self-produced polymeric matrix. The tolerance of biofilm-embedded bacteria to disinfectants is dependent on the biofilm structure and the physiological state of bacteria. Anoxic conditions and nutrient depletion is…

[…] biofouling in food processing plants. The SurfSAFE project aims to enhance the scientific and technological capacity of University of Porto in the fields of surface modification and biofilm analysis, promoting a European Network that guides the future development of tailor-made antifouling, antimicrobial, and non-biotoxic surfaces to reduce fouling and…

[…] subsequently form biofilms. Biofilms are specialised structures some bacteria form on surfaces that protect them from threats from the environment. “We have discovered that this increase in biofilm formation was due to chicken juice coating the surfaces we used with a protein-rich film,” said Helen Brown. “This film then…

[…] the importance of taking necessary sanitation measures at the packing shed and processing environment to prevent contamination of the produce. Specific characteristics of L. monocytogenes, such as biofilm-forming potential and tolerance against disinfectants, should be considered in developing sanitation strategies. The two outbreaks summarised above were chosen based on…

[…] packaging have to be ‘sterile’ and aseptically filled and sealed. This phase includes the most challenging steps in terms of controlling contamination risk to the product since biofilm formation, air recontamination and defective sealing can occur and cause a significant number of product sterility failures. The last phase encompasses…

[…] positive impact on ripening and aroma production of fermented meats and aroma production in cheeses through their proteolytic and lipolytic activities. Most recently, their ability to form biofilm and vancomycin resistance of a growing number of isolates is a major topic of concern for general public health due to…

Since spoilage depends both on the food matrix…

They also look to explore options of using this method in developing…
