Lignin-enzyme interaction: A roadblock for efficient enzymatic hydrolysis of lignocellulosics

Caoxing Huang et al.

Summary: Efficiently producing second-generation biofuels from biomass remains a long-term challenge due to biomass recalcitrance. Lignin significantly contributes to biomass recalcitrance by physically limiting enzyme access to carbohydrates. Research is focused on mitigating the negative effects of lignin on enzyme performance.

Synergy between endo/exo-glucanases and expansin enhances enzyme adsorption and cellulose conversion

Peiqian Zhang et al.

Summary: The effective binding between cellulases and cellulose is essential for the enzymatic hydrolysis of lignocellulose. Expansin can enhance the efficiency of cellulase by loosening the cellulose structure, and when combined, the hydrolysis rate of cellulose can increase significantly compared to using cellulase alone. These findings provide insights into the real-time synergy between cellulases and expansin on cellulose, and the impact of their synergy on the enzymatic hydrolysis of cellulose.

Influence of cellulose II polymorph nanowhiskers on bio-based nanocomposite film from Jatropha oil polyurethane

S. O. A. SaifulAzry et al.

Summary: This study aims to investigate the effect of cellulose II polymorph on Jatropha oil-based polyurethane (JOPU), by incorporating different weight percentages of CNW-II into JOPU films. The morphology of CNW-II was found to be granule-like, with a significant increase in tensile strength and water uptake proportional to the CNW-II content. Additionally, FTIR analysis and thermal degradation tests confirmed the dominance of JOPU spectra and similar trends in all films, respectively.

Molecular origins of reduced activity and binding commitment of processive cellulases and associated carbohydrate-binding proteins to cellulose III

Shishir P. S. Chundawat et al.

Summary: This study investigates the structural differences between cellulose I and cellulose III allomorphs and their impact on enzymatic hydrolysis efficiency. By monitoring enzyme-cellulose interactions using single-molecule force spectroscopy, it was found that reduced binding affinity of Cel7A on cellulose III leads to slower enzymatic activity. The findings suggest the use of simpler single-site models to explain the binding mechanisms between cellulolytic enzymes and cellulose.

The role of the particle size reduction and morphological changes of solid substrate in the ultrasound-aided enzymatic hydrolysis of cellulose

Emilia Csiszar et al.

Summary: The study investigated the contribution of ultrasound-aided particle size reduction to enzymatic hydrolysis efficiency and morphological changes of bleached cotton and linen powders. Results showed that linen particles were more sensitive to ultrasonication than cotton, with the horn-type reactor having a stronger impact. The smaller particles with increased accessibility led to higher concentration of reducing sugars and larger average size of residual particles after enzyme treatment.

Understanding the effects of different residual lignin fractions in acid-pretreated bamboo residues on its enzymatic digestibility

Wenqian Lin et al.

Summary: This study revealed that removing surface lignin significantly decreased the yield for enzymatic hydrolysis of DAP-BR and that the affinity constants of all tested lignins exhibited good correlations with the effects on enzymatic digestibility. Additionally, MWL samples showed a stronger affinity for cellulase enzymes compared to SL samples due to their higher molecular weight and hydrophobicity.
