| Outline of Final Research Achievements |
This study demonstrates the efficient ability of biogenic manganese oxides (BMO) produced by Acremonium strictum KR21-2 to sequester heavy metal ions (Mn(II), Co(II), Zn(II), Ni(II), Cd(II)) and rare earth element (Ce(III)). BMOs produced by A. strictum KR21-2 maintains Mn(II) oxidase activity and consequently can continue to oxidize Mn(II) to insoluble Mn(IV). This reduces the effect of competing Mn(II) on sequestration and provides new sorption site for heavy mental ions, resulting in enhanced sequestration efficiency. BMO can oxidize Co(II) to Co(III), and Ce(III) to Ce(IV). If BMOs is enzymatically active, reduced Mn(II) is readily reoxidized, resulting in a continuous oxidative sequestration of Co(II) and Ce(III) by BMOs.
