Kraft pulping, organosolv process and acid hydrolysis were applied on an elm clone. The solubilized lignins recovered analyzed. pulping led to with higher phenolic OH content as result of extensive cleavage ?-O-4? linkages, revealed by 13C solid state 13C?1H heteronuclear single quantum coherence nuclear magnetic resonance. This depolymerization also yielded lower molecular weight inferred size...
Degradation of lignin constitutes a key step in processing biomass to become useful monomers but it remains challenging. Compared to fungi, bacteria are much less characterized with respect to their lignin metabolism, although it is reported that many soil bacteria, especially actinomycetes, attack and solubilize lignin. In this work, we screened 43 filamentous actinomycetes by assaying their a...
