- Abstract:
- The present PhD thesis has been carried out in the frame of the ASIA LINK project ACULTURE (“The Re-establishment of Human Resources, Curricula, System and Institutions at the Agricultural Faculty of the Syiah Kuala University in Aceh). The main objectives of this thesis were to (i) investigate the effect of soil properties, fertilisation and regular agitation on the hydrocarbon (HC) degradation rates in aged contaminated soils and (ii) to study the response of Phaseolus vulgaris and its associated mycorrhizal fungi to heterogenous distribution of the HC contaminants in soil. The results of these two main experiments were published in peer-reviewed journals and comprise the PhD thesis. The results of these two studies indictate that (i) bioavailability is a crucial factor for efficient degradation of hydrocarbons in aged soils and future studies should focus on ways to enhance the bioavailability (e.g., by biosurfactants) of HC in aged soils; and (ii) the response of plants is different when grown on homogenously or heterogenously polluted soils and further effects are caused by heterogenous distribution of mycorrhizal fungi. More studies are needed which address the effect of heterogenous soil pollution, since the large variability of pollutant concentration is the typical field situation.
