Project type

Large-Scale EMSL Research

Mn(III/IV) oxides are potent scavengers and oxidants of numerous nutrients and contaminants within the environment. The oxidation and sorption capacity of Mn oxide phases, however, is highly…

Genome-enabled Investigations of the Role of Secreted Proteins and Reactive Metabolites in Carbon Degradation by Pure and Mixed Ascomycete Fungal Communities

FICUS Research

The Eumycete fungi (primarily Basidiomycota and Ascomycota) are key organisms in the degradation of wood, plant and animal material. While ascomycetes are less capable of rapid wood decay than…

Rapid Access: Justifying a Proposed Link between the Composition and Oxidative Capacity of Secretomes by Diverse Ascomycete Fungi

Lead Institution

Principal Investigator

Colleen Hansel

Project type

Limited Scope

Oxidized manganese, as both soluble Mn(III) and Mn(IV) oxides, is receiving increased attention as a dominant control on the degradation of lignin and decomposition of leaf litter. Both Mn(III) and…

Evolution of Fe(II) Mineralization Under Hydrodynamic Conditions Induced by Dissimilatory Iron-Reducing Bacteria

Lead Institution

Principal Investigator

Colleen Hansel

Project type

Exploratory Research

The reducing capacity of soils and sediments for contaminants will be dictated, in part, by the Fe(II) bearing solids produced by dissimilatory iron reducing bacteria (DIRB). A primary factor…
