Interests: manganese biogeochemistry; trace element cycles; biogenic mineral formation; redox and catalytic activities of biominerals
Iron and manganese oxide biominerals, which are produced via redox activities of microorganisms in aquatic and terrestrial environments, are of significance in both biogeochemical and environmental, technological contexts. An iron oxide biomineral, schwertmannite, occurring in acidic environments, incorporates metal oxyanions (e.g., As, Cr, Mo, and Se). A manganese oxide resembling poorly crystalline d-MnO2 serves as a fine adsorbent for metal cations and as a strong oxidant for inorganic and organic compounds, owing to its nanostructural and redox features. Such mineral functions (i.e., adsorption and redox and catalytic features) have raised important implications for environmental applications, including remediation or recovery of trace metal ions, decomposition of xenobiotic chemicals, and usage as a new material in industrial engineering.
We invite contributions on the formation of iron and manganese oxide minerals by microbially driven redox reactions; interactions of biomenerals with trace elements and inorganic and organic compounds; the mineral formation process and geochemical functions in aquatic and terrestrial environments; and their environmental applications. We especially welcome submissions where microbial contributions to interactions are discussed, as they have been shown to strongly affect the mineral functions. Studies on synthetic biomineral analogues and interaction mechanisms are also encouraged for submission.

Title: Precipitation of Biogenic Manganese Oxide Minerals as a Remediation Tool for Neutral Mine Drainage Containing Manganese(II) and Other Metal Ions
Author: Naoyuki Miyata
Abstract: The treatment of mine drainage is a significant concern worldwide because of severe impact of toxic metals in the environment. The microbial manganese (Mn) oxidation, leading to the precipitation of Mn oxide minerals, is considered a potential tool for clarifying mine drainages containing Mn(II); however, whether the microbial activity can function effectively under metal-rich, organic carbon-limited conditions remains to be elucidated. This study demonstrates that the Mn biomineralization can occur under the metal-rich, organic carbon-limited conditions, and this provides a promising strategy for remediation of mine drainages containing Mn(II) and other metal ions.
