Summary: The conventional two-step acid hydrolysis method for lignin determination in lignocellulose is laborious and time-consuming. A new ATR-FTIR spectroscopy method was developed in this study to easily and rapidly track fungal delignification. The ATR-FTIR spectra were correlated with the AIL content using PLSR with CV, and a reliable prediction model was obtained despite the heterogeneous nature of the fungal solid-state fermentation. This novel method can facilitate the transition to the wood-based economy.

Summary: Wheat straw was degraded by white rot fungi to obtain hydrolysate containing sugars, proteins, phenols, and enzymes, which was used as anolyte in a fuel cell to promote the growth of yeast Pichia fermentans and the formation of biofilm. The hydrolysate prepared using Phlebia floridensis and Phanerochaete chrysosporium showed the highest electrochemical response.

Summary: To compare the degradation of PLA composites by different microorganisms and understand the degradation mechanism, Actinomyces israelii, Aspergillus niger, Trichoderma harzianum, and Phanerochaete chrysosporium were chosen for degradation of PLA composites. The study analyzed the weight loss, functional groups, thermal properties, and crystallinity of the PLA composites before and after degradation. The findings showed that A. israelii and A. niger exhibited the strongest degradation ability, with weight losses of 7.14% and 6.99% respectively after 28 days, significantly higher than the control treatment. The degradation was mainly attributed to hydrolysis by the microorganisms and their enzymes. Presence of cracks and dents on the sample surface increased the contact area with microorganisms, leading to accelerated degradation. A. israelii and T. harzianum exhibited a higher tendency to degrade PLA in the composites. Microbial degradation also disrupted the crystalline region, making it easier for degradation to occur. These results provide insights into the microbial degradation mechanism of PLA composites and promote their application in various fields.

Summary: The addition of carbon sources to white rot fermentation straw can promote organic matter decomposition, shorten the fermentation cycle, and retain more nutrients in the straw feed. Glucose and molasses showed the greatest enhancement in the nutritional value of maize and rice straw after 14 days of solid-state fermentation. White rot fungi can improve the digestibility and palatability of poor quality straw.

Summary: This study investigates the effect of pH on the enzyme-catalyzed cleavage of beta-O-4 ' ether bonds and C-C bonds by lignin peroxidase isozyme H8. Results show that lowering pH can enhance the enzyme activity, reducing the energetic barriers for bond cleavage through protonation. It is suggested that engineering of lignin peroxidase isozyme H8 and other enzymes involved in lignin depolymerization should target stability at low pH.

Summary: This study investigates the potential of using targeted pretreatments in the feedstock supply chain to enhance lignin degradation in lignocellulosic biomass. The results show that inoculating corn stover with lignin degrading fungi and storing it under simulated storage conditions can lead to degradation of hemicellulose and lignin, resulting in sugar degradation products. Lowering the reaction temperature in the pretreatment process can achieve equivalent xylose release in both stored and fungal treated samples.

Summary: Optimizing the pretreatment conditions for lignocellulosic biomass is crucial for obtaining high purity fractions, especially a lignin polymer that can be easily used for valuable applications. This study used wheat straw as a sample and pretreated it in organic acid-based organosolv medium at mild conditions. The chemical structure and kinetics of lignin were analyzed using various techniques, and the modifications during the organosolv pretreatment were quantified. The extraction kinetics of lignin were successfully assessed using a potential degree of delignification model.

Summary: This study investigated the effect of regulating pH and Phanerochaete chrysosporium inoculation on lignocellulose degradation, humification process, and fungal community in composting. Results showed that composting with P. chrysosporium inoculation and pH regulation had higher cellulose decomposition and lignin degradation, improved enzyme activities, increased humic substance content, and more transformation of precursors. Inoculating P. chrysosporium affected fungal community diversity, and regulating pH promoted P. chrysosporium colonization. Network analysis indicated improved complexity and synergy between microorganisms in the treated group. Correlation and Random Forest analysis identified key taxa for lignocellulose degradation and humic acid formation in the treated group.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
