The project investigates fundamental links between the microscale organization of aquatic photosynthetic tissues and biofilm communities, their bio-optical properties and quantum efficiency.

The team involved in the project represents a multitude of expertises and a joint international effort. Besides the PI's group at University of Copenhagen, and a satellite group at the University of Technology Sydney, there is close interaction with groups in Australia, USA, Singapore, and Swiss (see links on this page).

The systems investigated encompass:

  • Single cells: Large algae/protists and bacteria
  • Defined and natural biofilms
  • Microbial mats:
    Hot springs and other extreme habitats
  • Aquatic macrophytes:
    Macroalgal and seagrass tissue
  • Marine symbioses:
    Corals, ascidians, foraminifera

Experimental techniques in the team encompass:

  • Electrochemical and fiber-optic microsensors
  • Imaging of chemical & physical variables
  • Imaging of photosynthetic activity
  • Imaging of cell motility and behavior
  • Hyperspectral imaging
  • Confocal and fluorescence microscopy
  • NanoSIMS
  • Cultivation of microbes
  • Microfluidics
  • Genomics and bioinformatics
  • Biophotonics
  • Sensor development
