A method for the separation and characterization of archaebacterial signature ether lipids
CA Mancuso, PD Nichols and DC White
A reproducible high performance liquid chromatography (HPLC) method for the
separation of diethers and tetraethers isolated from archaebacterial
phospholipids is reported. Fourier transform infrared spectroscopy was used
for structural confirmation of these signature lipids. A mixture of
tetraethers from a thermoacidophilic archaebacteria was resolved into three
major components by the normal phase separation. These components were
differentiated by Fourier self- deconvolution of infrared spectra. The
application of the HPLC technique to environmental samples may provide an
accurate assessment of archaebacterial biomass in various microbial
communities.
