Feb 24, 2024 · Purpose Co-composting of chicken manure and edible mushroom residue inoculated with oxytetracycline-degrading strain T4 was conducted to reduce the risk of residual oxytetracycline and tetracycline resistance genes (TRGs) to the ecological environment. Materials and Three treatments (CK: without bacteria agent T4 inoculated; AM: 1% bacteria agent T4 inoculated in mesophilic phase; AC
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 MnFe2O4 respectively. The properties and composit
Sep 19, 2019 · While studies have shown that anaerobic co-digestion of chicken manure (CM) and corn stover (CS) is an efficient method to treat these agricultural wastes, the microbial ecology of these systems and optimal parameters for the digestion process are yet to be determined.
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 i
Aug 26, 2014 · Effect of ammonia inhibition on microbial community dynamic and process functional resilience in mesophilic methane fermentation of chicken manure - Niu - 2015 - Journal of Chemical Technology & Biotechnology - Wiley Online Library.
Aug 1, 2023 · Transmission of ARGs during composting with different feedstocks (i.e., sheep manure (SM), chicken manure (CM) and mixed manure (MM, SM:CM = 3:1 ratio) was studied by metagenomic sequencing. 53 subtypes of ARGs for 22 types of antibiotics were identified as commonly present in these compost mixes; among them, CM had higher abundance of ARGs, 1.69 times than that in SM, while the whole
May 2, 2023 · The reactor can provide the desired fermentation conditions for hydrolysis, acidogenesis, and methanogenesis [97,98]. For example, CSTR can be combined with AnMBR to treat chicken manure, which realizes the treatment of chicken manure (TS 10%) by a membrane bioreactor.
Jun 30, 2016 · 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-resistant endophytic bacteria (AREB) in plant tissues
Jun 22, 2022 · One way to increase yields in agriculture using organic alternative is the introduction of manure-based composts into the soil. However, the use of such composts carries a risk of soil contamination with antibiotic resistance genes (ARG) from the gut and manure of the livestock. The contamination of the composts with heavy metals or antibiotics can increase this risk, while the
Jan 1, 2024 · Fig. 2 a shows the dominant bacterial clades and trends in all treatment groups during compost fermentation. Firmicutes, Actinobacteriota, Proteobacteria, and Bacteroidota were the most dominant clades, with 16S rRNA gene sequences accounting for more than 99%.
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.
Jan 31, 2024 · This study investigated the synergistic integration of clean technologies, specifically anaerobic digestion (AD) and struvite precipitation, to enhance nutrient recovery from chicken manure (CM). The batch experiments were conducted using (i) anaerobically digested CM digestate, referred to as raw sample (RS), (ii) filtered digestate sample (FS), and (iii) a synthetically prepared control
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
Nov 12, 2021 · 2.2. Structure Design and Construction of Fermentation Tank In this study the fermentation tank system was built on the outdoor ground, and a shelter was installed to avoid serious disturbance or rainwater accumulation. The structure of the fermentation tank includes blowers, pumping motors, and three-phase motors (Figure3).
Aug 1, 2022 · Chuenchart et al. (2020) has observed that optimum pH range for AD of chicken manure is pH 6.5–7.5 however, the pH of chicken manure falls short as it has been reported to be 6.1 ( Singh et al., 2018) hence, there is a need to adjust it prior for optimum biogas generation.
