Recent
Research Projects
Research goals center
on developing strategies for the bioremediation of polluted environments. Projects have included:
1. Addition of non-indigenous bacteria,
including genetically engineered microorganisms, to a contaminated
aquifer. This project is in cooperation
with the U.S. Geological Survey at the U.S.G.S. Groundwater Contamination Study
Site (Cape Cod, MA). Primary goals are
to define:
(a) in
situ conditions that are conducive to rapid degradation of target
pollutants by non-indigenous microorganisms, and
(b) ecological and bioremediative effects
which follow addition of genetically engineered microorganisms to aquifers.
2. Development of techniques using molecular
biology to identify and track target microbes in the environment and to measure
the effect of man's activities on the structure and activity of indigenous
microbial ecosystems.
3. Genetic and physiological analysis of diaryl
ether-degrading bacteria. Genes
encoding a dioxygenase responsible for the catalytic cleavage of diaryl rings
have been cloned and sequenced.
Bacteria with genetically modified catabolic pathways capable of
degrading recalcitrant pesticides are being developed and their fate and
activities analyzed in soils polluted with phenoxybenzoate-based
chemicals.
4. Modeling natural attenuation of TCE in a
marshland receiving TCE-contaminated groundwater. Additional objectives are to analyze the potential for oxidation
of TCE by methanotrophs and to observe any influence on the rate of degradation
of TCE by vegetation.
5. Analysis of whether biostimulation of
indigenous microorganisms can be used to accelerate the removal of organic
wastes from a contaminated aquifer that threatens to impact the Cedar River
(IA). The organic compounds were waste
products from a former manufactured gas plant.
6. Development of an organo-solv process for the
recovery of industrial products from oat hull residues. This project was done in cooperation with
and funded by the Biological Process Technology Institute, University of
Minnesota.
