Solid state 13c nmr
WebAfter solid-state fermentation of wheat straw with five lignocellulose-degrading fungi, lignin was extracted and studied by CPMAS 13C NMR. The increase in the intensity of the signals in the 200-164 ppm range is evidence for the oxidative alteration of lignin. The lignins degraded by the white-rot fungi Ganoderma australe and Phanerochaete chrysosporium … WebWe demonstrate that natural isotopic abundance 2D heteronuclear correlation (HETCOR) solid-state NMR spectra can be used to significantly reduce or eliminate the broadening …
