Enzymatic saccharification of Eucalyptus bark using hydrothermal pre-treatment with carbon dioxide.
In this study, saccharification of the inner bark of Eucalyptus was carried out by enzymatic hydrolysis to produce bioethanol from non-food biomass. To enhance the accessibility of the enzyme to theExpand

Direct mapping of morphological distribution of syringyl and guaiacyl lignin in the xylem of maple by time-of-flight secondary ion mass spectrometry.
Lignin, one of the main structural polymer of plant cell walls, varies in amount and monomeric composition among tissue and cell types, as well as among plant species. However, few analytical methodsExpand

Discriminating the indistinguishable sapwood from heartwood in discolored ancient wood by direct molecular mapping of specific extractives using time-of-flight secondary ion mass spectrometry.
A new method that can chemically discriminate the visually indistinguishable sapwood from heartwood in discolored woods is presented in this paper. Discriminating between sapwood and heartwood, whichExpand

Preparation and Characterization of Amphiphilic Lignin Derivatives as Surfactants
Abstract Acetic acid lignin (AL), one of the organosolv lignins, was modified by polyoxyethylation using commercially available polyethylene glycol diglycidylethers (PEGDE) having various chainExpand

Conversion of Technical Lignins to Amphiphilic Derivatives with High Surface Activity
Abstract To make use of technical lignins as a nonionic polymeric surfactant, we have already reported the modification of acetic acid lignin (AL) to amphiphilic derivatives by polyoxyethylationExpand

Ready chemical conversion of acid hydrolysis lignin into water-soluble lignosulfonate II: Hydroxymethylation and subsequent sulfonation of phenolized lignin model compounds
Highly condensed lignin can be transformed by three reactions — phenolation, hydroxymethylation, and neutral sulfonation — to water-soluble lignosulfonate. To elucidate reactivities and products inExpand

Formation and chemical structures of acid-soluble lignin II: reaction of aromatic nuclei model compounds with xylan in the presence of a counterpart for condensation, and behavior of lignin model
To elucidate the formation and chemical structures of water-soluble material in acid-soluble lignin (ASL), lignin aromatic nuclei model compounds of creosol (I) and 5-methoxycreosol (II) were reactedExpand

Conversion of technical lignins to functional materials with retained polymeric properties
A significant amount of technical lignins is produced in the pulp and paper industries. However, most technical lignins are burned for thermal recycling and a few percent are used as materials, suchExpand

The cryo‐TOF‐SIMS/SEM system for the analysis of the chemical distribution in freeze‐fixed Cryptomeria japonica wood
Initially, we investigated the distribution of chemicals in dried wood samples using a standard TOF-SIMS and obtained two-dimensional images of chemical distribution in various wood samples. However,Expand
