Summary: The optimal performance was achieved in the thermophilic anaerobic co-digestion process of sewage sludge with paper waste at a ratio of 4:6, where the COD removal efficiency and biogas production increased significantly. The addition of paper waste had a positive impact on the competition between carbohydrate and protein degradation, with cellulolytic bacteria becoming the predominant group.

Summary: This study investigates the effect of substrate organic composition on the anaerobic co-digestion of food waste and paper waste mixtures. The results show that the organic composition of the substrate has a greater impact on mesophilic co-digestion than thermophilic co-digestion. When the organic composition is carbohydrates:proteins:lipids = 6.8:1.8:1, the two co-digestion processes have similar biogas and methane production. However, when the organic composition is carbohydrates:proteins:lipids = 13.5:2:1, thermophilic co-digestion is more favorable. The characteristics of the thermophilic digestion process are more sensitive to changes in organic composition than the mesophilic digestion process.

Summary: This study investigated the role of biochar in the anaerobic co-digestion of waste activated sludge and food waste. The results showed that biochar facilitated the co-digestion process, particularly in the syntrophic methanogenesis of volatile fatty acids. The thermodynamic analysis revealed that biochar alleviated limitations imposed by high hydrogen partial pressure and expanded the thermodynamic windows. Furthermore, biochar triggered direct interspecies electron transfer and enhanced interspecies hydrogen transfer, promoting the syntrophic methanogenesis.

Summary: The long-term treatment of phosphorus-deficient wastewater using a one-stage partial nitrification-anammox (PNA) process may have negative effects on the growth of functional bacteria. A 650-day experiment was conducted using a lab-scale PNA system to study the impact of long-term phosphorus deficiency on nitrogen removal efficiency and sludge characteristics. It was found that phosphorus deficiency led to a decrease in nitrogen removal efficiency, high sludge volume index, and sludge bulking. The abundance of hzsA in flocs decreased significantly. However, the biofilm showed better resistance to phosphorus deficiency. After the addition of PO43--P, the nitrogen removal rate improved, and sludge bulking disappeared.

Summary: An anaerobic membrane bioreactor (AnMBR) was used to treat domestic sewage at 15 degrees C under different hydraulic retention time (HRT) conditions (6, 12, 16, and 24 h). The viability of microbial community in anaerobic digestion was assessed using Propidium monoazide (PMA)-PCR, which targeted microorganisms with intact cell membranes. The study found that a 6-hour HRT resulted in poor treatment performance, with low chemical oxygen demand removal efficiency and high mean trans-membrane pressure and flux. PMA-PCR combined with next-generation sequencing provided better identification of microbial changes compared to conventional 16S rRNA gene sequencing.

Summary: This study proposes high-salinity treatment as a novel strategy for inactivating nitrite-oxidising bacteria (NOB) and achieving stable partial nitritation (PN). The study found that NOB are more sensitive to high salinity than ammonia-oxidising bacteria (AOB), and increasing salinity inhibited nitrification. After high-salinity treatment, nitrite accumulation rate (NAR) was above 33% during nitrification. A novel process for achieving mainstream PN was proposed and evaluated based on the results.

Summary: Acorus calamus is recycled as an additional carbon source in microbial fuel cell-constructed wetlands for efficient nitrogen removal of low carbon wastewater. Alkali-pretreatment cleaves the benzene rings in dominant released organics, producing chemical oxygen demand of 164.5 mg per gram of A. calamus. Adding pretreated biomass in the anode of MFC-CW achieves maximum total nitrogen removal of 97.6% and power generation of 12.5 mW/m2.

Summary: This study used the innovative low-carbon nitrogen removal process of partial denitrification-anammox (PD-A) to simultaneously treat PPCCW and municipal wastewater pre-treated with 10 mg/L Fe3+. The results showed that the effluent had a total nitrogen concentration lower than 10 mg/L, with a removal efficiency of 79.67 +/- 3.48%. The dominant anammox genus was unclassified_f_Brocadiaceae, indicating the stability of the reactor. Hydrolytic acidifying bacteria SBR1031 and Bacillus increased substantially after feeding with actual wastewater, leading to increased removal efficiencies of organic material and nitrogen, suggesting a synergistic effect with PD-A bacteria. Finally, a novel wastewater treatment process that fully recovers carbon, phosphorus, and water was proposed.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
