Dissolution of kraft lignin in alkaline solutions [PDF]
International Journal of Biological Macromolecules, 2020 Lignins are among the most abundant renewable resources on the planet. However, their application is limited by the lack of efficient dissolution and extraction methodologies. In this work, a systematic and quantitative analysis of the dissolution efficiency of different alkaline-based aqueous systems (i.e.

Bacterial conversion of depolymerized Kraft lignin [PDF]
Biotechnology for Biofuels, 2019 Lignin is a potential feedstock for microbial conversion into various chemicals. However, the degradation rate of native or technical lignin is low, and depolymerization is needed to obtain reasonable conversion rates. In the current study, base-catalyzed depolymerization-using NaOH (5 wt%)-of softwood Kraft lignin was conducted in a continuous-flow ...
