WebSep 1, 2024 · Among several environmental signals known to regulate biofilm formation, iron availability has attracted the scientific community’s interest for a long time. This signal is particularly relevant during infection since human pathogens face severe iron restriction once inside the host. WebJul 30, 2008 · A comparison of infrared spectra of modern biofilms with modern collagen and fossil bone coatings suggests that modern biofilms share a closer molecular make-up than modern collagen to the coatings from fossil bones. Blood cell size iron-oxygen spheres found in the vessels were identified as an oxidized form of formerly pyritic framboids.
