Abstract

Pyrolysis-gas chromatography was applied to a study of the changes in organic material during fungal fermentation processing of wheat straw. Native straw samples were subjected to pyrolysis using a 100 CDS Pyroprobe heated filament pyrolyser coupled directly to the injector of the gas chromatograph. Twenty-one pyrolytic fragments were identified by retention times and mass spectrometry using an on-line gas chromatography/ion trap detector instrument. Pyrograms are reported, as well as quantitative and statistical analyses of fifteen compounds, showing significant changes for six compounds.
