Inhibition of lignin-derived phenolic compounds to cellulase [PDF]
Biotechnology for Biofuels, 2016 Lignin-derived phenolic compounds are universal in the hydrolysate of pretreated lignocellulosic biomass. The phenolics reduce the efficiency of enzymatic hydrolysis and increase the cost of ethanol production. We investigated inhibition of phenolics on cellulase during enzymatic hydrolysis using vanillin as one of the typical lignin-derived phenolics ...

Graphitization of Lignin-Phenol-Formaldehyde Resins [PDF]
Materials Research, 2020 Abstract Environmental friendliness and cost demand the development of lignin-modified phenolic (LPF) resins for application as a binder for carbon-containing refractories (CCRs) production. Moreover, the in-situ graphitization of such resins can produce crystalline carbon, which is an essential component of CCRs.

Two-step hydrogen transfer catalysis conversion of lignin to valuable small molecular compounds
Green Processing and Synthesis, 2017 As the major composite of biomass, lignin can be utilized as feedstock for valuable chemicals, especially phenols. Catalysis hydrogenation of lignin is an attractive route for the conversion. However, most of them require hydrogen gas under high pressure

Different types of phenolic units in lignins
BioResources, 2011 The influence of cross-linking and branching on the number of interconnections between lignin units and the number of end groups (phenolic and non-phenolic) in the lignin molecules is discussed. Branching results in an increased number of end groups.

Lignin studies of transgenic Norway spruce [PDF]
, 2006 An attractive objective in tree breeding is to reduce the content of lignin, or increase its extractability, to favor delignification during pulping. This study investigates the potential for lignin alterations in Norway spruce (Picea abies [L.] Karst ...
