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. In this study, the combined applica
2022/5/6/ · A sturdy and continuously growing biogas production was observed at all organic load rates, implying the synergetic effect on chicken manure and pig fat co-digestion. The highest specific methane yield, 441.3 7.6 L kg VS 1, was observed at an organic load rate of 4.5 kg VS (m3 day) 1.
This study explored the combined effects of Bacillus subtilis inoculation with biochar on the evolution of bacterial communities, antibiotic resistance genes (ARGs), and mobile genetic elements (MGEs) during the composting of chicken manure. The results showed that B. subtilis inoculation combined with biochar increased bacterial abundance and diversity as
After application of chicken manure organic fertilizer, the relative abundances of intI1 and intI3 in soil decreased by 4.71 × 10-5 and 2.57 × 10-7, respectively, while the relative
2016/6/30/ · Animal manure is commonly used as fertilizer for agricultural crops worldwide, even though it is believed to contribute to the spread of antibiotic resistance from animal intestines to the soil environment. However, it is unclear whether and how there is any impact of manure fertilization on populations and community structure of antibiotic
2022/10/1/ · The highest increase in soil available P was observed in T4 (12 t ha-1 chicken manure). Moreover, liming and chicken manure application significantly improved soil pH and decreased exchangeable Al
2022/8/4/ · reveal the factors most affecting the genes tet(A) and tet(X) during the process of chicken manure composting. The genes tet(A) and tet(X) encode two
2023/8/4/ · When chicken manure is incorporated into the soil, a significant (2–4 times) increase in the population of bacteria from the phyla Firmicutes, Bacteroidetes, and Actinobacteria is observed.
2023/11/13/ · The distribution of antibiotic-resistance genes (ARGs) in environmental soil is greatly affected by livestock and poultry manure fertilization, the application of
2023/4/1/ · 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.
2024/1/5/ · Here, the authors investigate the evidence for co-evolution of antimicrobial resistance in bacteria found coexisting in animals and the environment in chicken farms
Biochar is thought to be good sorbent for heavy metal and exploring ways to increase the efficiency of heavy metal adsorption by biochar is of great importance. Chicken manure biochar was modified with sulfur, hydroxyapatite and MnFe 2 O 4 respectively. The properties and composition of the pristine and modified biochar was characterized.
2021/11/12/ · Traditional chicken manure fermentation is mostly natural composting or exposure, which is not only time consuming but also susceptible to weather, resulting in uncontrollable quality and environmental pollution. This research aims to build a smart solar chicken manure fermentation system to control the conditions of chicken manure
2019/7/8/ · 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 …
