FRONT. MICROBIOL. 26/06/19 Preventing Biofilm Formation by Dairy-Associated Bacteria Using Peptide-Coated Surfaces. Introduction Biofilm-forming bacteria are known to be a major source of both spoilage and pathogenic microflora in the dairy industry (Elmoslemany et al., 2009).
Therefore, bacteria that form biofilms may adversely affect the safety and quality of milk and its products (Moretro and Langsrud, 2017). The main source of contamination of dairy products is often associated with the formation of biofilms on the surfaces of milk transport pipes, milking containers, and accessories in the dairy industries (Srey et al., 2013). Biofilms are established mainly under conditions that allow bacteria to easily adhere to the walls of the pipes, for example, when the milk is found in transport pipes without flow (Stoodley et al., 2002). The bacteria may detach from biofilms and contaminate the milk as it passes surfaces (Austin and Bergeron, 1995). One of the possible strategies to combat biofilm formation is by preventing bacterial adhesion to surfaces in advance (Palmer et al., 2007).

ONTARIO - 2006 - Titre: Maintien de la qualité du lait par la maîtrise des biofilms dans les lactoducs. Un biofilm est constitué de cellules bactériennes qui peuvent élever la numération sur plaque et abaisser la qualité du lait qui circule dans le lactoduc.
Les biofilms sont partout. Ils sont responsables de la plaque dentaire autant que de la viscosité observée sur les pierres des cours d'eau et à l'intérieur des vases à fleurs. Le monde médical et l'industrie s'intéressent beaucoup depuis quelque temps à la composition des biofilms et à la façon dont ils se forment et se propagent dans des conditions pourtant hostiles. Que sont les biofilms? Il s'agit tout bonnement d'un manteau de bactéries qui adhèrent à une surface et forment une couche capable de les protéger des détergents et des produits d'assainissement.
Une fois fixées, les bactéries commencent à se multiplier et à sécréter collectivement une substance polymérique extracellulaire (SPE).

This substitution caused changes in the traditional characteristics of cheese. Key words: biofilm, artisanal minas cheese, lactic acid bacteria, Serro, Serra da Canastra. Introduction The ways of manufacturing artisanal Minas cheese in two traditional producing regions (Serro and Serra da Canastra) are similar for milking and adding EC and rennet to milk.
