Summary: In this study of anaerobic digestion of chicken manure with varying chlorotetracycline concentrations, it was found that extracellular polymeric substances (EPS) play a protective role against chlorotetracycline by forming complexes to decrease degradation and increase adsorption. However, there is also a potential risk to the soil ecosystem from the adsorbed chlorotetracycline on EPS in sludge.

Summary: Management of chicken manure in Morocco has become a focus due to the increasing demand for chicken and eggs. The bioconversion of chicken manure into biogas can reduce the amount of manure while generating clean energy. Comparing with co-firing, pyrolysis, and gasification, anaerobic digestion of chicken manure was found to be superior in terms of energy gain.

Summary: Livestock and poultry waste contains a significant amount of phosphorus, and recycling this phosphorus can solve environmental pollution and reduce the need for phosphate rock. Adding a carbon source can greatly improve the release of phosphorus by changing the microbial community and lowering the pH. After appropriate treatment, the released phosphorus can be recovered as struvite.

Summary: Adopting waste-to-wealth strategies and circular economy models can help reduce biowaste and add value. Chicken manure can be converted into renewable energy through anaerobic digestion, but certain limiting factors need to be considered. Strategies to enhance digestion include co-digestion with other materials, addition of additives, and improving the bacterial community. Valorization of chicken manure can be achieved through composting, pyrolysis, and gasification. The use of chemicals such as biochar and conducting materials can also improve anaerobic digestion.

Summary: The presence of heavy metals in pig manure can inhibit biogas production and increase environmental pollution risk, while rice straw serves as a good co-digestion substrate and natural adsorbent. The study found that heavy metals were transformed into solid phase through adsorption during anaerobic digestion, with microwave and ultrasonic treatment improving adsorption properties, while alkaline treatment favored anaerobic digestion.

Summary: This review systematically summarized the migration and transformation of heavy metals (HMs) during anaerobic digestion and composting. The results showed that organic matter degradation increased the HMs content in biogas residue and compost (with the exception of As in compost). Most of HMs in biogas residue and compost exceeded relevant standards. Cd and As mainly converted the bioavailable fractions into stable fractions during composting, but As (V) toxicity needs to be concerned.

Summary: Bacteria have developed mechanisms to resist Cd toxicity, which are important for Cd detoxication and bioremediation. Through integrated analysis of transcriptomic and protein-protein interaction data, the global view of mRNA changes in Cd-induced cellular processes was revealed in Geobacter sulfurreducens. Differentially expressed genes were identified, and gene ontology and KEGG enrichment analyses showed significant effects on sulfur compound metabolic processes. Hub genes related to molecular chaperones were found to play important roles through PPI network analysis. A Cd-responsive transcriptional regulator ArsR2 was also identified, and its function in Escherichia coli was verified. This study provides new insights into Cd stress response and identifies a potential sensor element for Cd detection.

Summary: This study used a ball-milling method to enhance the defect structures of activated carbon, which showed excellent persulfate activation capacity for the degradation of model extracellular DNA and real antibiotic-resistant genes. The removal efficiency of extracellular DNA by defect-rich carbon with persulfate was 2.3 times higher than that by unmilled activated carbon. The research demonstrated that carbon defects not only enhanced the generation of reactive species, but also facilitated electron transfer between extracellular DNA and persulfate, leading to non-radical oxidation. The findings provide a new approach for utilizing defective carbon materials as persulfate activators for extracellular DNA pollutants and offer insights into the non-radical degradation mechanism of extracellular DNA.

Summary: Bacterial-algal symbiosis (BAS) is a promising carbon neutrality technology for wastewater treatment. However, there are still CO2 emissions due to slow diffusion and biosorption of CO2. To reduce emissions, the inoculation ratio of aerobic sludge to algae was optimized at 4:1 and CO2 adsorbent MIL-100(Fe) was immobilized on polyurethane sponge (PUS). This improved carbon sequestration efficiency and achieved zero CO2 emission in municipal wastewater treatment.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
