Fourier transform infra-red (FTIR) spectroscopy was used to assess carbon allocation in selected phytoplankton (Pediastrum duplex, Ceratium hirundinella, Anabaena flos-aquae) in a eutrophic lake. In contrast to bulk-analysis techniques, FTIR spectroscopy can provide information on carbon allocation at the species level within natural mixed populations.(More)
Synchrotron-based Fourier-transform infrared (FTIR) microspectroscopy was used to distinguish micropopulations of the codominant algae Microcystis aeruginosa (Cyanophyceae) and Ceratium hirundinella (Dinophyceae) in mixed phytoplankton samples taken from the water column of a stratified eutrophic lake (Rostherne Mere, UK). FTIR spectra of the two algae(More)

Microalgae produce metabolites that could be useful for applications in food, biofuel or fine chemical production. The identification and development of suitable strains require analytical methods that are accurate and allow rapid screening of strains or cultivation conditions. We demonstrate the use of Fourier transform infrared (FT-IR) spectroscopy to(More)
