WebDiatom silica cell walls present an intriguing application of biomineralization in a single celled organism. The ability of diatoms to make an enormous variety of silica structures … WebA model for Si transport in diatoms suggests uptake is controlled by the rate of cell wall silica incorporation through the intermediary of intracellular soluble Si pools (Conway et al., 1976; Conway and Harrison, 1977; Hildebrand, 2000; Hildebrand and Wetherbee, 2003). Three modes of Si uptake in diatoms, surge

Silica polymerization occurs in a compartment called the silica deposition vesicle (SDV) and it was proposed that the cytoskeleton influences silica patterning through the SDV membrane (silicalemma) via interactions with transmembrane proteins. Tesson and Hildebrand characterized insoluble organic material associated with valves and girdle bands from a variety of diatom species, and included staining and carbohydrate quantitation approaches to characterize associated carbohydrate polymers (Tesson and Hildebrand, 2013). Two types of polymer … See more The ability of diatoms to make silica-based cell walls has been the subject of fascination for centuries. It started with a microscopic observation by an anonymous English country nobleman in 1703, who observed … See more Silicon dissolved in an aqueous solution at neutral pH is primarily in the form of silicic acid, Si(OH)4 (Iler, 1979).
