Iron in bacterial biofilms
WebApr 13, 2024 · Abstract. The surface of intertidal estuarine sediments is typically covered with a photosynthetic biofilm. A large fraction of the carbon that is fixed is in the form of exopolymeric substances (EPS), providing the biofilm matrix. The consumption of organic carbon within the sediment column by heterotrophs bacteria is stratified according to the … WebFeb 12, 2024 · Microbially-induced corrosion is the acceleration of corrosion induced by bacterial biofilms. The bacteria in the biofilms oxidize metals on the surface, especially evident with iron, to drive metabolic activity and reduce inorganic species such as nitrates and sulfates. Coatings that prevent the formation of these corrosion-inducing biofilms …

WebThis episode features a conversation with Dr. Andrea Prinzi and Dr. Rodney Rohde. They talk about an article titled "The Role of Bacterial Biofilms in Antimicrobial Resistance" What are biofilms? What organisms are seen in them? What role do they play in antimicrobial resistance (AMR)? Tune in to find out. WebIron-bacteria biofilms alter the chemistry of well water by removing iron, manganese, and sulfate from solution and by increasing the pH. Sulfur-reducing bacteria and iron-sulfide mineral phases were observed in some samples of encrusting material, indicating that these bacteria could contribute to well-screen encrustation in some geochemical ...
WebSep 1, 2024 · These results indicated that iron is needed for the formation of biofilms by S. aureus SA113 (Lin et al., 2012). Bacteria require nearly 10 −6 mol/L concentration of iron for their growth. In other words, 1μM or higher concentrations of iron are needed to support bacterial growth and reproduction (Raymond et al., 2003).
