Summary: This study demonstrated the feasibility of using dewatered swine manure-derived biochar (DSMB) as an additive to enhance anaerobic digestion of swine wastewater for energy recovery and antibiotic resistance gene degradation. DSMB was found to accelerate methane production, reduce antibiotic resistance genes, and mitigate the risk of horizontal gene transfer, presenting a win-win solution for bio-waste management in swine farms.

Summary: Runoff from manured agricultural fields can transport antimicrobial resistance (AMR) contaminants, including genes and bacteria, to downstream ecosystems. This study quantified the ability of prairie strips to reduce the presence of antimicrobial resistance genes in manure-laden runoff and characterized the impact of manure on prairie soil microbiomes over time.

Summary: Swine manure treatment plants are important reservoirs of plasmid-harboring antibiotic resistance genes (ARGs) and physicochemical contaminants. This study revealed the changes in plasmid and ARG abundances, as well as their interactions with the physicochemical properties of manure during the treatment process. The findings showed that anaerobic and aerobic digestion were the most effective stages for reducing ARG abundance, but plasmids associated with ARGs were not effectively removed. Additionally, pH, total nitrogen, total phosphorus, and certain heavy metals significantly affected the abundance of ARG subtypes.

Summary: The addition of biochar significantly increased methane yield during anaerobic digestion of swine manure, while reducing the abundance of antibiotic resistance genes. Furthermore, biochar indirectly affected ARGs by altering microbial structure and the integrase gene intI1.

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.

Summary: This study found that adding biochar and H3PO4 modified biochar during swine manure composting can effectively reduce the soluble concentration of heavy metals, decrease the total abundance of antibiotic resistance genes and heavy metals resistance genes, and this reduction is related to changes in the bacterial community.

Summary: Concerns about biological risk in the environment have been increasing. Manure has been considered a significant source of antibiotic resistance genes (ARGs) in agricultural soil. However, the extent of microbial contamination in different manure-amended soils, including ARGs, virulence factor genes (VFGs), and human bacterial pathogens (HBPs), remains largely unknown. This study used a metagenome-based approach to investigate changes in resistome, VFGs, and HBPs in soils treated with commonly used manures. The results showed that ARGs, VFGs, and HBPs from manure could be spread into soils, and their diversity and abundance varied significantly depending on the type of manure used. The study also found a positive co-occurrence pattern between ARGs and HBPs, VFGs and HBPs, as well as ARGs and VFGs. Pig manure and silkworm excrement samples had higher levels of microbial contamination compared to other samples, suggesting that the use of these two manures increased the risk of HBPs and the dissemination of ARGs. This study confirms the prevalence and differences in resistome, VFGs, and HBPs in different manure-amended soils.

Summary: This study investigated the impact of adding humic acid (HA) on antibiotics and antibiotic resistance genes (ARGs) in swine manure composting. The results showed that the addition of 6% HA significantly reduced the levels of antibiotics and ARGs and improved microbial structure and product quality. Therefore, adding HA to compost can improve compost quality and safety, and mitigate the circulation of ARGs in the environment.

Summary: The study aimed to investigate the impact of an acute disturbance of nutrients from manure on freshwater sediment microbiomes. Results showed that nutrients from manure had a significant effect on the microbial community in sediment, leading to a lack of recovery after 28 days, while nutrients from laboratory-derived sources caused a continuous change in microbial community composition.

Summary: Manure from swine livestock contains pathogenic bacteria and resistance genes against veterinary and clinically critical antibiotics, posing potential health risks. Comparative measurements of manure and hospital wastewater show the presence of facultative pathogens and critical resistance genes, indicating a risk for the dissemination of these genes.

Summary: The distribution and transfer of intracellular and extracellular antibiotic resistance genes (ARGs) in manure anaerobic digestion process with biochar were investigated. The results showed that the anaerobic digestion process effectively removed extracellular ARGs, and the modified biochar reduced the absolute copy number of extracellular resistance genes. The process also inhibited the growth of host bacteria, effectively removing intracellular ARGs. The study further revealed that biochar induced oxidative stress response and enhanced the antioxidant capacity of microorganisms, thereby inhibiting the horizontal transfer of ARGs.

Summary: This study evaluated the effects of adding nano-Fe2O3 on methane production and antibiotic resistance genes (ARGs) during anaerobic digestion of swine manure. Nano-Fe2O3 decreased methane production but improved the methane production rate at shorter exposure times. The addition of nano-Fe2O3 reduced the abundance of certain ARGs. Environmental variables and microbial community were identified as major factors influencing ARGs.

Summary: Composting is an effective strategy for reducing antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in animal manure. This study examined the fate of ARB and ARGs after applying swine-manure composts (SMCs) to different soil types. The results showed that SMCs initially increased total ARG abundance in the soil but significantly reduced it after 82 days. The SMCs introduced specific ARGs into the soils, which declined over time. However, the presence of SMCs increased the number of ARB in the soils, especially cefotaxime-resistant bacteria. The microbiome also took longer to recover compared to the control. Statistical analysis suggested that changes in the microbial community were the main factor influencing the fate of ARGs during SMCs land application.
