Thermal decomposition of lignin structural modification in termite digested softwood (II)

► Application of TG/DTG analysis for characterization of termite digested softwood. ► Friedman method for thermal kinetics calculation of biomass at varied heating rates. ► Gauss and Lorentz model for DTG deconvolution. ► Termite selectively modified softwood-lignin structure but no degradation. ► Remarkable changes in thermal behavior of lignin after termite digestion.
