Pyrolysis/gas chromatography/mass spectrometry as a useful technique to evaluate the ligninolytic action of streptomycetes on wheat straw

Degradation of lime wood painting supports

“…This is one of the reasons of the lower stability of S lignin-units towards biodegradation. The calculation of the S/G ratio based on the results of analytical pyrolysis has shown that this indicator is promising to be employed in the studies of the processes of wood ageing and the effect of different fungi on the processes of biodegradation of different lignins [16,[37][38][39]. To find the changes in the S and G lignin structural units in lime wood samples of aged art objects, S-and G-type phenols were separately normalized to 100% ( Table 4).…”

Studies on pyrolysis of wheat straw residues from ethanol production by solid-state fermentation

“…Including our work [13][14][15], studies on the thermochemical conversion of forest and agricultural residues have been previously done by many research groups [16][17][18][19]. Some studies on wheat straw pyrolysis have also been conducted [20][21]13]. However, pyrolysis of the wheat straw residue (WSR) from ethanol production by solid-state fermentation has not been reported yet, so we are interested in this new material for pyrolysis studies and hope to find out some new results.…”

Thermal transformations of pine wood components under pyrolysis/gas chromatography/mass spectrometry conditions

“…What is needed badly in the pulping research area are rapid methods of analysis that can provide detailed qualitative information and even, in relative terms, quantitative information. Analytical pyrolysis has been shown to be a valuable technique to characterize lignins, where most of pyrolytic fragments are diagnostic compounds in which the structure of the main building blocks is preserved [5][6][7].…”
