摘要: Abstract A water-soluble extract from a forest soil, rich in microbubble surfactants, has been geochemically characterized using elemental, infrared, and X-ray diffraction measurements, pyrolysis mass spectrometry, carbohydrate determinations, amino acid analyses. Moreover, the low solubility water, (soil-derived) spectra, iodine-stained thin-layer chromatography of surfactant mixture indicated that lipids, previously unidentified, probably also represent major component mixture. Last, we provide additional data on biochemical heterogeneity identify probable natural source its characteristic glycopeptide fraction.
