Biology

The area biology at the IHD comprises the areas of mycology and molecular biology as well as wood science/wood anatomy, wood protection and wood modification.

Technical-organisational subdivisions are the Mykolabor Dresden with research and development activities on microbiology/mycology and molecular biology, the Wood Anatomy Laboratory and the Wood Drying/Wood Modification Technical Centre.

Molecular diagnostics and bioinformatics

Gel-electrophoresis
Gel-electrophoresis
  • Qualitative and quantitative DNA diagnostics of microorganisms (especially fungi, bacteria, algae) by means of PCR, real-time PCR, PCR-ELISA, DNA array and sequencing (conventional and NGS)
  • Sequence and database analyses (NCBI)
  • Design of PCR primers, array probes and RFLP patterns

Microbiology, mycology, biotechnology

  • Diagnostics of microorganisms (e.g. by cultivation, microscopy)
  • Building biology, indoor hygiene
  • Investigations on mould
  • Further development of biological test methods
  • Biotechnical modification of materials
  • Production and application of enzymes
  • Mushroom cultivation (edible and medicinal mushrooms)
  • Development of substrates for plants and cultivated fungi
  • Development of fungus-based materials
Test cultures (fungi)
Test cultures (fungi)

Material protection against fungi, bacteria and algae

Algae extracts
Algae extracts
  • Efficacy of biocides
  • alternative operating principles in material protection
  • biological resistance of wood, materials and coatings
  • interaction between materials and harmful organisms

Wood anatomy and wood knowledge

  • Macro- and microscopic examinations on wood anatomy
  • Characterisation of wood features and wood properties
  • Deduction of structure-property relationships
  • Microscopic examinations of interfaces (e.g. coatings, glue lines)
  • Wood species identification (leaflet)
  • Wood species identification at wood-based panels (Video)

Wood protection and wood modification

Heartwood decay
Heartwood decay
  • Development and optimisation of materials and measures for wood and material protection
  • Development and adaptation of methods for testing and diagnostics
  • Further development off thermal wood modification
  • standardisation work within DIN and CEN comittees "Durability of Wood and wood products"
  • Collaboration in specialist committees and associations of wood protection
