Effects of Different Treatments on Postharvest Callus Formation and Metabolic Mechanisms in Taro [PDF]

open access: yesShipin Kexue
In this study, taro samples were artificially wounded and then underwent hot water treatment (HWT) at 65 ℃ or hot air treatment (HAT) at 30 ℃, whereas those naturally wounded served as a control.

Heterologous Expression of Laccase From Lentinula edodes in Pichia pastoris and Its Application in Degrading Rape Straw

open access: yesFrontiers in Microbiology, 2020
Rape straw cannot be efficiently degraded and utilized by ruminants due to its severe lignification and complex cross-linked structure between fiber and lignin. The laccases can catalyze the inter-unit bond cleavage in lignin substrates.

Lignin Phenol Formaldehyde Resoles Using Base-Catalysed Depolymerized Kraft Lignin [PDF]

open access: yesPolymers, 2018
Lignin phenol formaldehyde (LPF) resols were produced using depolymerized lignin fractions at various levels of phenol substitution (50 to 70 wt %). To produce monomeric-rich (BCD-oil) and oligomeric (BCD-oligomers) bio-based phenolic compounds, softwood kraft lignin was base-catalysed degraded.

Changes in plant lignin components and microbial necromass matter with subtropical forest restoration

open access: yesGeoderma
Soil organic carbon (SOC) represents the largest carbon reservoir in terrestrial ecosystems. Therefore, understanding how to enhance SOC is crucial for the global carbon cycle and atmospheric CO2 removal. While there has been reported on SOC accumulation

Study on the Relationship between the Structure and Pyrolysis Characteristics of Lignin Isolated from Eucalyptus, Pine, and Rice Straw through the Use of Deep Eutectic Solvent

open access: yesMolecules, 2023
Understanding the pyrolysis product distributions of deep eutectic solvent (DES)-isolated lignins (DESLs) from different types of biomass is of great significance for lignin valorization.

Three invasive insects alter Cycas micronesica leaf chemistry and predict changes in biogeochemical cycling

open access: yesCommunicative & Integrative Biology, 2016
Leaf litter chemical traits were measured for Cycas micronesica plants in Guam following leaf herbivory by the scale Aulacaspis yasumatsui, the butterfly Chilades pandava caterpillar, or the leaf miner Erechthias sp. to determine the influence of the non-

Aromatics from Beechwood Organosolv Lignin through Thermal and Catalytic Pyrolysis

open access: yesEnergies, 2019
Biomass fractionation, as an alternative to biomass pretreatment, has gained increasing research attention over the past few years as it provides separate streams of cellulose, hemicellulose, and lignin.

The synthesis and analysis of advanced lignin model polymers [PDF]

open access: yes, 2015
This work was funded by the EP/J018139/1, EP/K00445X/1 grants and an EPSRC Doctoral Prize Fellowship.If the lignin-first biorefinery concept becomes reality, high quality lignins close in structure to native lignins will become available in large ...

Carbon isotope anomaly in the major plant C-1 pool and its global biogeochemical implications [PDF]

open access: yes, 2004
We report that the most abundant C-1 units of terrestrial plants, the methoxyl groups of pectin and lignin, have a unique carbon isotope signature exceptionally depleted in C-13.
