Manganese-oxidizing fungi support bioremediation through the conversion of manganese ions into manganese oxide deposits that in turn adsorb manganese and other heavy metal ions from the environment. Manganese-oxidizing fungi were immobilized onto nanofiber surfaces to assist remediation of heavy metal–contaminated water. Two fungal isolates, Coniothyrium sp. and Coprinellus sp., from a Superfund site (Lot 86, Farm Unit #1) water treatment system were incubated in the presence of nanofibers. Fungal hyphae had strong association with nanofiber surfaces. Upon fungal attachment to manganese chloride–seeded nanofibers, Coniothyrium sp. catalyzed the conformal deposition of manganese oxide along hyphae and nanofibers, but Coprinellus sp. catalyzed manganese oxide only along its hyphae. Fungi–nanofiber hybrids removed various heavy metals from the water. Heavy metal ions were adsorbed into manganese oxide crystalline structure, possibly by ion exchange with manganese within the manganese oxide. Hybrid materials of fungal hyphae and manganese oxides confined to nanofiber-adsorbed heavy metal ions from water.

Manganese oxide is one of the most attractive inorganic materials because of its structural flexibility and wide applications in catalysis, ion exchange, electrochemical supercapacitors, molecular adsorption, biosensors, and so on. In recently, manganese oxides nanomaterials, including MnO, MnO2and Mn3O4, have attracted great interest as anode materials in lithium-ion batteries and water treatment due to their high theoretical capacity, environmental benignity, low cost, and special properties. Hence, manganese oxides nanostructures with excellent properties and various morphologies have been successfully synthesized. Herein, we provide a recent development of the synthesis of manganese oxides nanomaterials and their application.

P Release

<p>Flooding caused by snowmelt runoff in the spring and early summer and heavy rainfall in the summer could enhance P release into nearby surface water bodies causing eutrophication. Six soil amendments were tested for their effectiveness  in reducing P release from flooded-soils. Soils were collected from the flood-prone fields in the Red River Valley region in Manitoba, Canada. The tested amendments were gypsum, magnesium sulphate, alum, ferric chloride, zeolite and manganese oxides. Intact soil columns were subjected to flooding for 8 weeks at 4<sup>o</sup>C simulating the snowmelt in the spring and the early summer and at 22<sup>o</sup>C simulating flooding occurrences in the summer.  Release of soil P into soil solution and floodwater was higher at 22<sup>o</sup>C than that at 4<sup>o</sup>C. Gypsum, magnesium sulphate, alum and ferric chloride were effective in reducing the concentrations of P in the pore- and flood-water at various capacities. Ongoing research on zeolite and manganese oxide suggests that manganese oxide was more effective in reducing soluble P concentrations in soils at early days of flooding.</p>
