Synthesis of temperature and pH responsive lignin-grafted sulfobetaine for efficiently recycling cellulase

Feiyun Li et al.

Summary: Recycling cellulase can reduce the cost of lignocellulosic enzymatic hydrolysis. A lignin-grafted sulfobetaine (LSB) was synthesized and showed a sensitive response to pH and temperature. LSB could be dissolved under the conditions of lignocellulosic enzymatic hydrolysis and co-precipitated with cellulase after hydrolysis, resulting in significant cellulase savings.

Carbohydrate-aromatic interface and molecular architecture of lignocellulose

Alex Kirui et al.

Summary: In this study, the assembly of lignocellulosic components in plant stems and the interactions between polysaccharides and the aromatic polymer lignin are investigated using solid-state NMR spectroscopy. The research shows that the extent of glycan-aromatic association varies in different types of plant stems, and lignin primarily interacts with xylan through non-covalent interactions and partially binds to the junction of xylan and cellulose surface. The unique feature of homogeneous mixing of all molecules in softwoods enables better water retention. These findings provide insights into the principles of polymer interactions underlying the heterogeneous architecture of lignocellulose, which can guide the rational design of more digestible plants and more efficient biomass-conversion pathways.

Second-generation bioethanol production from corncob - A comprehensive review on pretreatment and bioconversion strategies, including techno-economic and lifecycle perspective

Pradeep Kumar Gandam et al.

Summary: This study discusses various strategies for second-generation bioethanol production from corncobs, focusing on the effects of different pretreatment methods, detoxification methods, and fermentation approaches on ethanol yield. The results show that a combination of acid and alkali pretreatments along with proper detoxification steps can achieve high ethanol yields. Additionally, using genetic engineering to construct inhibitor tolerant and consolidated bioprocessing compatible microbes is another way to achieve an economical process.

Facile Tailoring of Structures for Controlled Release of Paracetamol from Sustainable Lignin Derived Platforms

Mario Culebras et al.

Summary: The study successfully synthesized hydrogels using lignin, a non-valorized biopolymer, crosslinked with PEGDGE. The ratio of crosslinker used influenced the structural and chemical properties of the resulting hydrogels, with increased crosslinker amount leading to smaller pore size and higher swelling capacity. Paracetamol release test showed higher drug diffusion for hydrogels produced with a lignin:PEGDGE ratio of 1:1.
