Times Cited Count：23 Percentile：78.84(Multidisciplinary Sciences)Miscanthus sinensis Andersson is a pioneer plant species that grows naturally at mining sites. can detoxify aluminium (Al) by producing phytosiderophores. Root-endophytic Chaetomium cupreum, which produces microbial siderophores, enhances Al tolerance in M. sinensis. We identified the siderophore produced by C. cupreum as oosporein. It was revealed that oosporein could detoxify Al. Inoculation test of C. cupreum onto M. sinensis in acidic mine soil showed that C. cupreum promoted seedling growth, and enhanced Al tolerance.

Chaetomium cupreum was isolated from the root of Miscanthus sinensis. The siderophore was collected and purified, and the function of the siderophore was investigated. The siderophore was identified as oosporein. C. cupreum increased Al tolerance in M. sinensis via accumulating and detoxifying Al into their mycelia using oosporein, and via changing the Al localization pattern in the roots, which was more efficient to detoxify Al.

Radium-226, a descendant nuclide of 
U, is of serious concern in Ningyo-toge Environmental Engineering Center because its radioactive concentration in mining wastewater exceeds the effluent standard. In this study, we examined Ba and Sr adsorption on biogenic Mn oxide as a preliminary surrogate for Ra adsorption. Both Ba and Sr show the dependence of adsorption on NaCl concentration. Overall, Ba gave an order of magnitude higher Kd values than Sr. Adsorption behavior of Ra would be similar to that of Ba in terms of ionic radius. Barium showed Kd value greater than 10
in 10 mM NaCl solution, similar to the ionic strength of the fresh water system in the Ningyo-toge center. Therefore, it is expected that the biogenic Mn can work effectively for removal of Ra from mining wastewater.
