A Transition Metal‐Free Approach for the Conversion of Real‐Life Cellulose‐Based Biomass into Formate

open access: yesAdvanced Science, EarlyView.
A visible‐light‐mediated method has been developed for the direct conversion of biomass into formate at ambient temperature and atmospheric pressure. This approach achieves the selective generation of hydroxyl radicals, which subsequently transform sugars, cellulose, and hemicellulose into formate.

Exploring the Interplay Between Formation Mechanisms and Luminescence of Lignin Carbon Quantum Dots from Spruce Biomass [PDF]

open access: yesarXiv
This study investigates the intricate relationship between the formation mechanisms and luminescent properties of lignin-derived carbon quantum dots (LG-CQDs) synthesized from spruce biomass by hydrothermal treatment. A comprehensive understanding of LG-CQD structure and its photoluminescence requires insights into the native architecture of lignin and

Structural and Biochemical Characterization of a Widespread Enterobacterial Peroxidase Encapsulin

open access: yesAdvanced Science, EarlyView.
Encapsulins are self‐assembling bacterial protein compartments loaded with cargo enzymes. The most abundant encapsulin cargo class are Dye‐decolorizing Peroxidases (DyPs). In this study, we structurally and biochemically characterize a DyP encapsulin found in many enterobacteria.

Mechanisms of Baicalin Alleviates Intestinal Inflammation: Role of M1 Macrophage Polarization and Lactobacillus amylovorus

open access: yesAdvanced Science, EarlyView.
Baicalin alleviates E. coli‐induced intestinal inflammation through dual mechanisms: direct inhibition of the TLR4/IRF/STAT signaling pathway to modulate macrophage polarization and antigen presentation, thereby regulating Th17/Treg cell differentiation; and microbiota‐mediated indirect effects via increasing Lactobacillus amylovorus abundance and ...

Minimizing Energy Demand in the Conversion of Levulinic Acid to γ‑Valerolactone via Photothermal Catalysis Using Raney Ni

open access: yesAdvanced Science, EarlyView.
Upgrading lignocellulosic wastes into value‐added compounds represents an excellent option to reduce the current overreliance on fossil fuels. γ‐Valerolactone is especially attractive for its multiple applications such as biofuel or green solvent.

Mini-review: Current Understanding of the Correlation of Lignin Structure with Biomass Recalcitrance

open access: yesFrontiers in Chemistry, 2016
Lignin, a complex aromatic polymer in terrestrial plants, contributes significantly to biomass recalcitrance to microbial and/or enzymatic deconstruction. To reduce biomass recalcitrance, substantial endeavors have been exerted on pretreatment and lignin
