cattle manure compost equipment for chicken manure enhanced corrosion resistance

Jul 21, 2023 · The upgraded composting equipment’s improved mixing structure, ventilation heating system, and automation level ultimately contributed to the enhanced efficiency of livestock manure composting and increased the utilization value of the resulting organic fertilizer.

Apr 30, 2024 · Livestock manure is one of the most important pools of antibiotic resistance genes (ARGs) in the environment. Aerobic composting can effectively reduce the spread of antibiotic resistance risk in livestock manure. Understanding the effect of aerobic composting process parameters on manure-sourced ARGs is important to control their spreading risk. In this study, the effects of process

Aug 1, 2021 · Ma et al.'s (2019) study showed that the ARGs removal rate could be increased by 75% with nZVI injection of 160 mg/L during anaerobic digestion of cattle manure compared to the control group

Aug 4, 2023 · Chicken manure and composts derived from it are valuable organic fertilizers that have a positive impact on soil fertility and significantly enhance crop yields.

Apr 1, 2023 · Antibiotic residue in husbandry waste has become a serious concern. In this study, contaminated chicken manure composting was conducted to reveal the bioaugmentation effect on tetracyclines residue and antibiotics resistance genes (ARGs). The bioaugmented composting removed most of the antibiotics in 7 days.

Feb 1, 2024 · DOI: 10.1016/j.cej.2024.149581 Corpus ID: 267717707; Electrokinetic technology enhanced the control of antibiotic resistance and the quality of swine manure composting @article{Li2024ElectrokineticTE, title={Electrokinetic technology enhanced the control of antibiotic resistance and the quality of swine manure composting}, author={Binxu Li and Muhammad Fahad Sardar and Xu Zhang and Jing Ye and

Sep 4, 2017 · Manure in intensive farming should be composted before being discharged into the field, while grazing livestock manure is not suitable for composting due to an increased number of resistance genes

Jan 1, 2024 · In summary, our results showed that the FM treatment achieved 97% removal efficiency of ARGs and 96% reduction in the total abundance of MGEs during chicken manure composting. Firmicutes and Actinobacteriota might play an important role in the spread and harmful effects of ARGs.

Jun 1, 2023 · Global livestock manure production is estimated to be nearly 6.3 billion tons per year [1]. In China, approximately 1.38 billion tons of cattle manure is produced every year [2]. Cattle manure contains considerable pathogens and antibiotics, which may cause environmental problems [3].

Jan 20, 2022 · The use of livestock manure is an important way for antibiotic resistance genes (ARGs) to enter the environment, and composting is an effective method for removing ARGs from livestock manure. In

Abatement of antibiotic resistance genes (ARGs) in livestock manure by composting has attracted attention. This study investigated the effect of adding magnesium-modified biochar (MBC) on ARGs and microbial communities in chicken manure composting. Twelve genes for tetracyclines, sulfonamides, and m

Chicken manure (CM) can pose a serious threat to environmental and human health, and need to be managed properly. The compost can effectively treat CM. However, there is limited research on the heavy metals and antibiotic resistance genes (ARGs) during compost CM.

This study examined the effects of three Bacillus strains and one Saccharomyces cerevisiae strain on nitrogen transformation and microbial communities in pig and chicken manure compost. The findings revealed that the use of compound microbial inoculants increased the compost temperature, accelerated

This study explored the effects of Bacillus subtilis at four levels (0, 0.5%, 1%, and 2% w/w compost) on the variations in ARGs, mobile genetic elements (MGEs), and the bacterial community during composting. The composting process had a greater impact on ARGs than Bacillus subtilis. The main ARG detected was sul1.

Jul 8, 2019 · Livestock manure is an important pathway by which antibiotic resistance genes (ARGs) enter the environment. To reduce the occurrence of antibiotic resistance genes in manures, we studied the variations of ARGs and mobile gene elements (MGEs) during the 46-day co-composting of chicken manure with Chinese medicinal herbal residues.
