Manganese - Wikipedia
网页Characteristics. Physical properties. Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. [9] . Manganese and its common ions are paramagnetic. [10] . Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. [11] Isotopes.

网页A fungal enzyme, manganese peroxidase, oxidizes manganese +2 atoms to manganese +3, which are then sent to the tiny spaces within the wood lattice. Manganese +3 is highly reactive and can break down the chemical bonds of lignin, making it available as food for the fungus. Fungi are not the only organisms that harness the power of manganese ...
