In this study Fourier transform infrared micro-spectroscopy (FTIR) was used to determine lipid and carbohydrate content over time in the freshwater microalgae Chlamydomonas reinhardtii and Scenedesmus subspicatus grown in batch culture in limiting concentrations of nitrogen (N). Both algae exhibited restricted cell division and increased cell size following(More)
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)
Fig. S1. Comparison of the effect of different data processing methods of FT-IR spectra on sample clustering, using C. reinhardtii grown in either standard TAP, Low P TAP, or Low N TAP media. PCA score plots of cut-down spectra processed using EMSC2 normalisation without derivatisation (a, b), spectra converted to their 1 st derivative before EMSC2(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)
