Bioactive Molecules in Agroecology

Graduate School of Science and Technology at Aarhus University

Objectives of the course:
Thousands of molecules influence the biological interactions in ecological systems. The overall objective of the course is that the students achieve understanding of the importance of bioactive molecules in agroecological interactions. The students get acquainted with bioactive plant defense compounds, phytochemicals, contaminants and pesticides and will obtain the qualifications for explaining how the structure of the compounds determines their uptake in neighbouring biological organisms or in mammal consumers, their possible beneficial or negative effects as well as their transformation in soil or biological organisms. Student qualifications will cover both theoretical understanding and experience in performing laboratory assays related to fate and effects of bioactive compounds.

Learning outcomes and competences:
On completion of the course the students have attained competence to: 

  • Classify bioactive compounds of importance in agriculture on basis of their structure, physico-chemical properties and their origin.
  • Explain the degradation (aerobic and/or anaerobic) and sorption processes of small bioactive molecules in soil, water, and atmosphere, and conclude on the factors that influence these processes.
  • Use LC-MS/MS equipment for quantitation of bioactive molecules and their degradation products in soil, plants and biofluids
  • Model the kinetics for bioactive compound degradation in soil
  • Evaluate the applicability of the newest practical methods used in bioactive molecules research: quantitative measurements of residues in the environment and body fluids, toxicological cell tests, toxicological test on nematodes, uptake and transformation in plants and mammals, effect of natural compounds fed to bees on the bees’ capacity of transforming pesticides.
  • Explain the principles of Absorption, Distribution, Metabolism, Excretion (ADME) of bioactive molecules, including Phase 1 and Phase 2 metabolisation processes.
  • Report and discuss data from laboratory tests.

Course contents:
The course is constructed as follows:

Preparatory reading of selected parts of textbook

Theoretical lessons:

  • Small bioactive molecules in agriculture – wanted or unwanted  (I: contaminants)
  • Ecotoxicology beneficial insects
  • Small bioactive molecules in agriculture – wanted or unwanted (II: natural compounds)
  • Absorption, distribution, metabolisation and excretion (ADME) of bioactive compounds
  • Toxicology testing
  • Degradation kinetics
  • Contaminants in agriculture coming from sludge

Laboratory experiments:

  • Does the pesticide bentazone have a potential for leaching to groundwater?
  • Effects of plant defense benzoxazinoids on non-target soil organisms?
  • Using a maize root culture system to study metabolisation of contaminants
  • Bioactive benzoxazinoids in bread – excretion in urine from rye-bread-eating students
  • Testing the toxicity of a common detergent on fibroblast proliferation and survival 
  • Will bees’ intake of a dietary phytochemical affect their capability of metabolising pesticides?
  • Subsequent elaboration of reports on the laboratory experiments.

Course assessment:
Elaboration of a 30- to 40-page report on the total of six laboratory experiments (Take-home assignment, to be handed in no later than two weeks after the end on the on-site study period). For PhD students the report is assessed as "passed" or "not passed". Presence at a minimum of 90% of theoretical and practical lessons is required to obtain the course diploma. For MSc students the assessment will use the 7-point grading scale. Grading will be with internal co-examination.

Comments from participants in our 2018 course

“The course was very well structured. It was easy to follow the course, because of the good connection between theory and practice”

“It was impressive how we went through so many different themes in the short period of time”

“Very good methodological variation”

“I liked the small group, the number of teachers and the time that was on hand (however, you always run short on time)”

“Nice to have a folder with the printed hand-outs”
