  1. Bacterial destruction of wooden cultural heritage Charlotte Björdal1, Thomas Nilsson1 and Rene Klaassen2 1 Faculty of Forestry, Swedish university of Agricultural Sciences, Sweden 2 SHR, Foundation of Timber research, the Netherlands

  2. Wood in historical context

  3. Small bacteria makes great harm

  4. Venice Foundation poles supporting historical buildings

  5. Shipwreck and other archeological remains Roman ship Wooden castle

  6. BACPOLES Preserving cultural heritage by preventing bacterial decay of wood in foundation piles and archaeological sites European Commission (energy, environment and sustainable development the city of tomorrow and cultural heritage) EVK4-CT-2001-00043 2002 - 2005

  7. Aim and objectives Identify the bacteria responsible for decay 2. Development of methods for protection of cultural heritage

  8. • Wood sampling • Environmental monitoring At: 24 sites in Europe BACPOLES based on

  9. Outcome of BACPOLES

  10. DNA/RNA identification Identification of bacteria Cytophaga-Flavobacteria-Bacterioides

  11. Decay progessing at all 24 sites • Bacteria active and alive in both poles and archaeological wood • Activity even in very old wood (2500 years) • Adapted to environments low in inorganic nutrients Bacterial decay in Europe

  12. Based on bacterial identification, bacteriophages/ virus killers were developed Impregnation/ incapsulation in situ Friendly chemicals Development of preservation methods

  13. BISKUPIN, Poland Future work Protection of wooden remains in situ

  14. BRYGGEN, Norge Future work Preservation and protection of wooden foundation supporting historic buildings

  15. The BACPOLES research team members are gratefully acknowledged for fruitful cooperation. The European commission, 5th framework programme, for funding. Acknowledgement
