Jun 1, 2017 · In the present study, four different proportions of BC (0, 5%, 10%, and 20%) were added to chicken manure and the changes in three types of ARGs (tetracycline resistance genes, tet: tetC, tetG, tetW, and tetX; sulfonamide resistance genes, sul: sul1, sul2, dfrA1, and dfrA7; and macrolide resistance genes, erm: ermB, ermF, ermQ, and ermX) and an
Aug 4, 2023 · conductivity (by 2 – 2.5 times), and the quantity of water-resistant a ggregates (by 5 – 10%). The application of these fertilizers also promotes biological
Mar 9, 2023 · All materials in contact with the manure or biogas should be corrosion resistant. For instance, PVC plastic was used for the slurry handling pipes in the Penn State digester. The design should incorporate alternative of moving slurry or biogas through the system. A blocked pipe could result in backed up slurry spilling from the digester.
Jan 5, 2024 · Here, the authors investigate the evidence for co-evolution of antimicrobial resistance in bacteria found coexisting in animals and the environment in chicken farms and slaughterhouses in China.
Metal losses due to corrosion in poultry manure environments [3]. “Reproduced with permission from Safley, L.M.; Westerman, P.W., Bioresour. Technol. published by Elsevier, 1992”. Metal Type Original Weight in g/cm2 The Average Rate of Metal Loss (g/cm2/month) % of Metal Remaining (mass) Duration of Tests (months) Manure collection pit BS
In this study, 454-pyrosequencing was used to investigate the distribution and composition of ARBs in chicken manure and fertilized vegetables. The prevalence of ARB in the samples of the chicken manure compost recovered from farms on which amoxicillin, kanamycin, gentamicin, and cephalexin were used was 20.91-65.9% for ARBs and 8.24-20.63%
Apr 8, 2021 · However, the effects of animal manure fertilization on the ARG of vegetable endophytes remain unknown. In this study, high-throughput quantitative PCR (HT-qPCR) was used to explore the effects of poultry manure fertilization on the bacterial community and resistome in the soil, root endophytes, and leaf endophytes from Cichorium endivia L.. The
The study focuses on the following: (1) biochar and hydrochar production under different process conditions for production of carbon-rich fuel from poultry manure; (2) phosphorus recovery by acid leaching–alkali precipitation from manure ash, biochar, and hydrochar; and (3) activated carbon production from acid-leached hydrochar and biochar.
Jun 1, 2021 · Cattle manure and poultry litter are widely used as fertilizers as they are excellent sources of nutrients; however, potential adverse environmental effects exist during land applications, due to the release of zoonotic bacteria and antimicrobial resistance (AMR) genes.
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
Jan 1, 2024 · Transposase genes were more strongly associated with resistance genes than integrase genes, suggesting that MGEs, particularly transposases, dominant the number and properties of ARGs in feces (Wu et al., 2022). After applying compost-treated poultry manure to the soil, intI-1(clinic) and tnpA-04 abundance, increased
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 w
Aug 1, 2022 · Often times, biochar rich in nitrogen acquired from wet torrefaction of poultry manure serves well as a pH absorbent which indicated that it is a prime candidate for application as sorption materials for water purification from heavy metals or from organic pollutants due to the abundance of surface functional groups (Straten et al., 2018). 3.
May 12, 2020 · The goal of this study was to determine if the composting of poultry manure at a field scale would result in the reduction of antibiotic residues, pathogenic bacteria, and antibiotic resistance genes (ARGs) in the final fertilizer product. A 10-week composting of poultry manure spiked with enrofloxacin, doxycycline, and ciprofloxacin was performed.
Jun 5, 2021 · Livestock manure is a major source of antibiotic resistance genes (ARGs) that enter the environment. This study assessed the effects of inoculation with mature compost (MC) on the fates of ARGs and the bacterial community during swine manure composting.
