Milestones in the Biochemistry of Silicon: From Basic Research to Biotechnological Applications.

6.7 Gigatonnes of silicon are processed each year by marine organisms. Since it was known that silicon is an essential element for many biological systems, significant advances in the biochemistry of this element have been achieved from the classical viewpoint of silicon being a purely inorganic element. This article describes the proteins, genes, and molecular mechanisms of silicon metabolism in diatoms and sponges. These studies may help to reveal the role of silicon for optimal development and growth in many plants and animals as well as initiate the development of new technological methods for the shape-controlled production of new patterned silicone-based materials.
