Abstract
Water extracts from fresh wheat and barley straw. straw incubated with Pleurotus ostreatus, and straw compost were studied by IR, H-1 NMR, a nd C-13 NMR spectroscopy. During incubation lignin was degraded, water extractability increased, and water extracts were rich in polysacchar ides. After composting solubility decreased and the water extracts wer e rich in aromatic, methoxyl, and carboxyl C, but poor in O-alkyl C in dicating that during composting mainly polysaccharides had been minera lized. GPC revealed that water extracts from straw compost contained p olysaccharides, peptides, C- and O-substituted aromatics, and alkyl co mpounds.
