Projects
Microbial iron oxidation in wetland environments
Wetland plants are adapted to anoxic conditions by forming aerenchyma and able to maintain oxic conditions in their root systems and the rhizosphere. In doing so, the plants favor chemical and microbial oxidation processes and hence interere with all kinds of geochmeical cycles in an otherwise anoxic environment. The presence of plaques of oxidized iron around the roots of wetland plants indicates an activie iron cycling in the rhizosphere.
The so called iron plaques play an important role in wetlands by increasing metal sequestration which has been used for mediation of heavy metal contaminations. Besides, they have extensive interactions to many other microbial and chemical proecess.
Although the role of iron-oxidizing bacteria in the deposition of iron around the roots is more and more recognized, hardly anything is known yet about the biotic and abiotic constraints of the activities of these organisms. under neutral conditions, iron-oxidizing bacteria have to compete with other oxygen-consuming processes, both microbial and chemical ones.
In this project relevant iron-oxidizing bacteria are being enriched and isolated in pure culture. the isolated strains will be indentified with molecular techniques and their distritution in nature will be studied by application of specific oligonueleiotide probes. Their activities will be studied in model systems consisting of oxygen-limited chemostats, artifical root systmes and gnotobiotic plant systems.
