Lipid chemistry and biochemistry, natural products of marine origin, lipidic pollutants and metal cations in marine environment.
Summary of Research Activities
Research interest concentrates on marine fungi, inhabiting the shelf zone of the Atlantic Ocean in Canadian Maritimes. A multidisciplinary approach to the study, which is currently conducted, attempts to collect experimental results, which would add to our understanding of the life cycle and the role of marine fungi in their habitat.
In the area of organic chemistry of natural products, lipidic metabolites of marine fungi are isolated from fungal cultures, and their structure elucidated on the basis of analytical data (NMR, IR, UV-VIS, GCMS spectra). The complement of metabolites and their biological activity is expected to provide information on the ecological biochemistry of marine fungi, in the way of identification of active metabolic pathways and possible interactions with other organisms in the habitat.
A role of marine fungi in the food chain may be elucidated on that basis, taking into account occurrence of lipids and other biomolecules in oceans. Environmental aspects of research entail an assessment of the influence exerted by xenobiotics on the life cycle of marine fungi (growth rate, changes in the complement of metabolites, etc.). Xenobiotics such as hydrocarbons of different types (including aliphatic, aromatic hydrocarbons and their chlorinated derivatives) and metal ions, are commonly found in marine shelf zone as a result of both natural processes and human activity.
