Revealing the structure and distribution changes of corn stalk lignin ...
WEBOct 1, 2023 · Therefore, we focus on the spatial and temporal variation of lignin removal during lignocellulose depolymerization by using corn stalk as a feedstock and reaction in a 1, 4-dioxane/water system. The migration rule and chemical structure change of lignin during the process of lignin removal were investigated.
Assessment of key features of lignin from lignocellulosic crops: Stalks ...
WEBDec 15, 2016 · Lignins from stalks of corn and sugarcane (LCorn stalk and LSCane stalk) showed the highest content of total phenolic OH groups (2.7 and 2.5 mmol/g lignin, respectively) comparatively to cotton and tobacco stalks (1.8 …
Lignin degradation by Coprinus comatus in corn stalk
WEBSep 15, 2023 · The results showed that the strain got its degradation of lignin up to 38.66 %. The strain eroded structure of corn stalk and formed pores, which accelerated the degradation of lignin. Treated by Coprinus comatus increased the specific surface area and reduced the crystallinity of corn stalk.
WEBIn this study, a strain with selective degradation of lignin in corn stalk was isolated and identified. The culture conditions for the enzyme production of the strain including carbon and nitrogen sources, incubation time and temperature, Cu2+ …
Lignin degradation in corn stalk by combined method of H
WEBNov 19, 2015 · Lignin, hemicellulose, and cellulose are the three major chemical components of corn stalk (CS). As a macromolecule and highly branched polymer, lignin forms the lignin sheath and surrounds hemicellulose and cellulose, which protects the cellulose and hemicellulose from degradation by cellulase and hemicellulase [ 2 – 4 ].
Lignin degradation in corn stalk by combined method of H2O2
WEBNov 19, 2015 · In our previous work, in order to shorten the pretreatment time and increase the lignin degradation, we have pretreated the corn stalk (CS) using a combination of Aspergillus oryzae CGMCC 5992 solid-state fermentation and H2O2 treatment.
Green Modification of Corn Stalk Lignin and Preparation of ...
WEBApr 12, 2018 · In this study, corn stalk lignin was used to react with non-volatile and non-toxic glyoxal under the catalysis of a sodium hydroxide solution, and a wood adhesive based on glyoxalated corn stalk lignin was prepared.
Extraction, chemical composition, and characterization of …
WEBThe lignin, which is responsible for flexibility and stiffness of the fiber wall (Varanasi et al. 2013), was found to be present in the corn husk at a more remarkable percentage than in the corn hull and stalk counterparts. A minor concentration of ash was observed in the composition of corn hull and husk fibers, while the ash concentration ...
Effect of carboxylated and quaternized lignin and epoxidized lignin …
WEBIn this study, the lignin produced from corn stalk pretreated with p-toluenesulfonic acid (PCS) was used to prepare carboxylated and quaternized lignin (CQCL) and epoxidized lignin (ECL), and the effect of the two modified lignin …
