SPP 1315: Microbial metabolism of model pesticides in the drilosphere and effect on N2 O production: Linking processes with populations
Project
Project code: DFG SPP 1315
Contract period: 01.01.2007
- 31.12.2010
Purpose of research: Basic research
Hypotheses:
1. The drilosphere (i.e., burrow linings, gut content, and casts) harbours hitherto unknown, highly active prokaryotes that transform phenoxyacetic acid herbicides and their degradation products.
2. Phenoxyacetic acid herbicides and their degradation products inhibit N2 O production and growth of hitherto unknown nitrifiers and denitrifiers in the drilosphere.
Aims:
To assess the microbiology of the drilosphere
1.Fate of pesticides and degradation products (MCPA and 2,4-DCP)
2.Effect of pesticides on N2 O production by denitrifiers and nitrifiers
3.Identify and isolate key prokaryotes associated with pesticide degradation and N2 O production
