Carrageenophyte identification by second-derivative Fourier transform infrared spectroscopy


The second-derivative mode of the Fourier transform I.R. spectra of dried algal material has been applied to distinguish the carrageenans-producingStenogramme interrupta from the isomorphous speciesRhodymenia howeana. Spectra of the tetrasporophyteS. interrupta showed bands assigned to a λ-carrageenan type polysaccharide, while the gametophytic and… (More)
