The aim of the DHYVA project is to understand how bacterial metabolisms interact in pollutant degradation and to estimate the effect of bioturbation on these activities in order to:

  • assess oil degradation in sandy/muddy sediment, in situ in mesocosms and in the laboratory in microcosms
  • assess the influence of oxic/anoxic cycles on the fate of the oil
  • obtain insight into the bacterial diversity in the sediment and estimate the impact of oil compounds on bacterial communities
  • characterise the products of oil transformation following bacterial degradation
  • obtain information on the transfer of organic and metallic pollutants from one compartment to another and towards the food chain (sediment/water/burrowing organisms)
  • assess the influence of burrowing organisms and bioturbation on oil degradation
  • isolate and characterise bacterial consortiums and streams capable of degrading hydrocarbons in anaerobic and aerobic conditions.

The DECAPAGE project follows on from this project.
