Abstract

Main objectives of the project are: 1.Determination of the intensity and duration of the `trigger molecule¿ response in a wide range of soils of different properties using `trigger molecules¿ ranging from `simple¿, e.g. glucose and amino acids, to complex, e.g. root extracts. 2. Identification of different classes of `trigger molecules¿ in complex mixtures (e.g. root exudates) based upon separation and `trigger molecule¿ response. 3. Validation or rejection of the `microbial metabolite¿ theory, i.e. is the biomass responding directly to fresh inputs of `trigger molecules¿ or to microbial metabolites produced from them? 4. Determination of the source(s) of `trigger molecules¿, i.e. endocellular reserves, soil organic matter or both. 5. Determination of which microbial groups are stimulated by different `trigger molecules¿.
