Different microplastics distinctively enriched the antibiotic resistance genes in anaerobic sludge digestion through shifting specific hosts and promoting horizontal gene flow

Tianyi Luo et al.

Summary: This study reveals that polyethylene (PE) and polyvinyl chloride (PVC) microplastics (MPs) have different impacts on the abundance and dissemination of antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in anaerobic sludge digestion. PVC MPs promote the acquisition of ARGs by human pathogen bacteria and functional microorganisms, while PE MPs do not. Horizontal gene flow (HGF) is observed to be a possible mechanism for new bacteria to acquire ARGs in MPs-stressed digester.

New strategy of drinking water sludge as conditioner to enhance waste activated sludge dewaterability: Collaborative disposal

Tingting Xiao et al.

Summary: By using heated modification drinking water sludge (HDWS) as a conditioner to enhance the dewaterability of waste activated sludge (WAS) through its properties, the collaborative disposal of drinking water sludge (DWS) and waste activated sludge (WAS) can be achieved. The mechanism of HDWS+O-3 enhanced WAS dewaterability was explained through pyridine-infrared analysis and density functional theory (DFT) calculations. The discovery of HDWS+O-3 applied to effectively enhance WAS dewaterability provides an inspiring perspective on the emerging DWS and WAS co-processing disposition.

Choline chloride pretreatment on volatile fatty acids promotion from sludge anaerobic fermentation: In-situ deep eutectic solvents-like formation for EPS disintegration and associated microbial functional profiles upregulation

Wangbei Cao et al.

Summary: This study developed an innovative choline chloride (ChCl)-based approach for the treatment of waste activated sludge (WAS), resulting in increased production of volatile fatty acids (VFAs). The use of ChCl accelerated the solubilization, hydrolysis, and acidification processes of WAS, leading to a higher yield of VFAs. Additionally, ChCl had screening effects that enriched hydrolytic and acidogenic anaerobes and inhibited VFAs consumers, creating a more favorable microbial metabolic profile for efficient VFAs production.

Xian Yang et al.

Summary: The high moisture content of sludge is a key factor limiting its subsequent treatment and disposal. A novel method using MnFe2O4-biochar activated peroxymonosulfate combined with tannic acid was effective in improving sludge dewaterability. The treatment not only enhanced the sludge dewaterability and calorific value, but also improved the pore structure of sludge biochar, showing promise for resource utilization.

Partial ozonation of returned sludge via high-concentration ozone to reduce excess sludge production: A pilot study

Xiangjuan Sun et al.

Summary: By comparing the effects of high and low concentration ozone on partial ozonation of returned sludge, it was found that high concentration ozone can more effectively reduce organic matter and excess sludge production, with stronger nutrient removal capacity. While there were no significant differences in the treatment properties of excess sludge, the advantages of high concentration ozone mainly lie in the sludge solubilization rate and impact on carbon source utilization capacity in bioreactors.

Insight into using a novel ultraviolet/peracetic acid combination disinfection process to simultaneously remove antibiotics and antibiotic resistance genes in wastewater: Mechanism and comparison with conventional processes

Qian Ping et al.

Summary: The study found that UV/PAA-H disinfection was most effective for removing tetracyclines, quinolones, macrolides, and beta-lactams, while NaClO disinfection was effective for removing sulfonamides. The majority of ARGs were well removed after UV/PAA-H disinfection, but specific genes increased after NaClO disinfection. The highly reactive oxidation species generated from the UV/PAA process were responsible for the elimination of antibiotics and ARGs.

Molecular Insight into the Binding Property and Mechanism of Sulfamethoxazole to Extracellular Proteins of Anammox Sludge

Gui-Feng Li et al.

Summary: Antibiotics, such as sulfamethoxazole, can interact with extracellular proteins of anammox sludge, leading to fluorescence quenching and structural changes. The binding process is enthalpy-driven, and the aromatic proteins show the strongest quenching effect. Molecular simulations suggest that sulfamethoxazole can disrupt the structure of extracellular proteins through hydrogen bonding and hydrophobic interactions.

Enhanced removal of antibiotic resistance genes and mobile genetic elements during swine manure composting inoculated with mature compost

Jia Wang et al.

Summary: Livestock manure is a major source of antibiotic resistance genes entering the environment. Inoculation with mature compost prolonged the thermophilic period and promoted the decomposition of organic matter during swine manure composting. The reduction of ARGs and MGEs, especially sulfanilamide resistance genes, was mainly attributed to the rapid growth and reproduction of thermophilic bacteria in the compost.
