Summary: Efficient depolymerization of crystalline cellulose requires the cooperative action of multiple cellulolytic enzymes. This study demonstrates that the synergistic activity between cellobiohy-drolases and a lytic polysaccharide monooxygenase can enhance the activity and performance of the enzymes by producing chain breaks and amorphizing the crystalline surface of cellulose.

Summary: This study investigated the efficiency and kinetics of the photoactivated periodate process for degrading 2,4-dichlorophenol in water, finding that UV/IO4- had a higher degradation rate than UV alone, regardless of pH. By adjusting the concentration of periodate and 2,4-DCP, the degradation rate and removal efficiency could be controlled effectively.

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: The presence of Fe in biochar enhances the degradation of organic pollutants through Fenton-like reactions. However, reactive oxygen species (ROS) have a limited role in this degradation process. The study investigates the adsorption and degradation of 2,4-dichlorophenol (2,4-DCP) in Fe-biochar systems. The results show that adsorption and degradation are kinetically associated, and ROS quenching and competition from similar compounds inhibit 2,4-DCP degradation.

Summary: Nitrogen-doped biochar (NCMs) have shown potential as metal-free catalysts for persulfates, with conductivity and graphitic N being key properties in determining the degradation efficiency of 2,4-dichlorophenol. The positive effect of conductivity is attributed to the mediated electron-transfer mechanism, while graphitic N serves as the main active site for PMS activation. Understanding the evolution of NCMs' properties with preparation conditions and their correlations with reactivity is meaningful for preparing nitrogen-doped biochar and developing high-performance carbonaceous materials for persulfates-based AOPs.

Summary: The study focused on Phanerochaete chrysosporium, the primary fungal source for lignin degrading enzymes, particularly manganese peroxidases (PcMnPs). Through in silico and gene expression analysis, five potential PcMnPs were identified with varying transcript accumulation under different stress conditions. PcMnPs were particularly expressed at later growth stages and induced by stresses like MnSO4, H2O2, and heat, showing their potential for lignin biodegradation.

Summary: Despite the abundance of research on ligninolytic enzyme production, these enzymes have not yet been effectively utilized to combat environmental pollution. This study improved the production of ligninolytic enzymes through solid-state fermentation with Phanerochaete chrysosporium ATCC, using the Taguchi method and agro-industrial waste as substrate. Optimization of factors such as humidity, inoculum concentration, packed density, and time led to a significant increase in enzyme production and process efficiency.

The isolate showed tolerance to 2,6-DCP up to 300 mg/L and exhibited growth and degradation capabilities under specific conditions. The findings of this study provide a promising fungal isolate for the bioremediation of chlorinated phenols in soil.

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 developed a g-C3N4 with N2C-type defects/MoO3 Z-scheme photocatalyst (D-CN/MoO3) for the degradation of microcystin (MC-LR) in visible light. The D-CN/MoO3 could photodegrade 100% of MC-LR within 25 min, which was significantly higher than pure g-C3N4. The degradation mechanism was found to be the selective attack of 1O2 on the Adda side chain of MC-LR and subsequent decarboxylation reaction of h+, leading to effective mineralization and reduced toxicity of MC-LR. The D-CN/MoO3 also demonstrated excellent stability and adaptability, showing potential for decontamination of MC-LR in eutrophic water.
