Research Activities
• Bioremediation
strategies based on microbial biodegradation processes for worst-case
scenarios (e.g. spill) of soil contamination with chlorinated
s-triazine herbicides, or other xenobiotics.
• Bioassays based on the simple eukaryotic models
Saccharomyces cerevisiae
and Caenorhabditis elegans
for the screening
and diagnosis of the toxicity of environmental chemicals (and their
metabolites), inclusive of predicting biomarkers and mechanisms of
toxicity.
