Brazilian Journal of Microbiology Available online 9 February 2017 Growth, viability and architecture of biofilms of Listeria monocytogenes formed on abiotic surfaces. Abstract The pathogenic bacterium Listeria monocytogenes can persist in food processing plants for many years, even when appropriate hygienic measures are in place, with potential for contaminating ready-to-eat products and, its ability to form biofilms on abiotic surfaces certainly contributes for the environmental persistence.

In this research, L. monocytogenes was grown in biofilms up 8 days attached to stainless steel and glass surfaces, contributing for advancing the knowledge on architecture of mature biofilms, since many literature studies carried out on this topic considered only early stages of cell adhesion. In this study, biofilm populations of two strains of L. monocytogenes (serotypes 1/2a and 4b) on stainless steel coupons and glass were examined using regular fluorescence microscopy, confocal laser scanning microscopy and classic culture method.

Int J Food Microbiol. 2016 Apr 16;223:63-74. Genes involved in Listeria monocytogenes biofilm formation at a simulated food processing plant temperature of 15 °C.

At 15 °C, disruptions in genes dltB, lmo1080, lgt, lmo1068 reduced biofilm formation. Himar1 Tn insertions in flaA, cheR, lmo0543, lmo1224 increased biofilm formation. Several biofilm mutants were resistant to DNase, proteinase K or pectinase treatments. Susceptibility to benzalkonium chloride decreased with biofilm maturity and amount. Abstract Listeria monocytogenes is a pathogenic foodborne bacterium whose persistence in food processing environments is in part attributed to its biofilm formation.

Abstract A total of 98 previously characterized and serotyped L. monocytogenes strains, comprising 32 of 1/2a; 20 of 1/2b and 46 of 4b serotype, from clinical and food sources were studied for their capability to form a biofilm.

The microtiter plate assay revealed 62 (63.26%) strains as weak, 27 (27.55%) strains as moderate, and 9 (9.18%) strains as strong biofilm formers. Among the strong biofilm formers, 6 strains were of serotype 1/2a and 3 strains were of serotype 1/2b. None of the strain from 4b serotype exhibited strong biofilm formation. No firm correlation (p = 0.015) was noticed between any serotype and respective biofilm formation ability.

Biofilms: Impact on the Food Industry

Maintaining good oral health has always been important to me and was stressed in our family when I was growing up. As my father used to quip, “Be true to your teeth or your teeth will be false to you.” The dental hygienist cleaning my teeth asked if I brush my teeth manually or if I use an electric toothbrush.

FOOD PRODUCTION 29/09/09 Listeria biofilm under attack from new disinfectant .

L. monocytognes can thrive on the work surfaces of meat processing plants because it can withstand low temperatures and can even grow in or on refrigerated foods. The hardy pathogen is also a serious public health problem. According to the US Department of Agriculture (USDA), L. monocytognes causes serious illness in 2,500 people a year, resulting in 500 deaths. Collaboration To help companies fight the problem, Sterilex Corporation joined forces with Agriculture Research Service (ARS) microbiologist Judy Arnold.

Biofilms are layers of protein and polysaccharides that surround bacteria and stick to equipment surfaces. The new formulation developed by Arnold and Sterilex penetrates a biofilm, kills the microorganisms, and removes the biofilm.
