May 1, 2019 · As the presence of antimicrobials in manure can select for antimicrobial-resistant bacteria, manure has become a reservoir of antibiotic compounds, antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) (Heuer et al., 2011; Knapp et al., 2008). The World Health Organization has listed colistin as a critically important
However, the effects of BC on antibiotic resistance genes (ARGs) during chicken manure composting are still unclear. This study investigated the effects on ARGs of adding different proportions of BC (0%, 5%, 10%, and 20% w/w) to chicken manure compost. After 26 days, the relative abundances (RAs) of most ARGs (tetC, tetG, tetW, tetX, sul2
The influence of compound microbial agents on antibiotic resistance genes (ARGs) in pig manure composting was investigated. The results show that the addition of microbial agents promoted the reduction of total ARGs and the maximum removal efficiencies for absolute abundance (77.2%) and relative abundance (64.5%) were observed in the repeated
Apr 1, 2021 · A few studies have shown composting to be effective at reducing Escherichia coli carrying ampicillin, kanamycin, and tetracycline resistance, as well as Acinetobacter and Enterobacteriaceae carrying resistance to erythromycin and tetracycline in antibiotic-dosed swine manure, cattle manure and poultry waste [40,41,42,43].
Mar 15, 2024 · These large amounts of antibiotic residues in livestock manure induce antibiotic resistance in animal gastrointestinal microorganisms [2]. Antibiotics introduced into the environment induce the production of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs), which pose a risk to the environment and public health [3], [4].
Nov 1, 2019 · Composting decreased abundance of most ARGs in manure, but increased the persistence of manure-introduced ARGs in soil irrespective of fertilization history, especially for those from farm manure. These findings help understanding the fate of ARGs in manured soil and may inform techniques to mitigate ARGs transmission.
Sep 21, 2023 · Manure is best for fertilizing lawns. Manure is cheaper than compost because it’s easier to produce. For this reason, it’s the perfect choice for fertilizing your lawn — especially once it’s been dethatched. Dethatching is the process of removing the layer of dead foliage between the soil and the lawn.
In this study, we compared 3 different dairy manure composting —anaerobic fermentation (AF), static compost (SC), and organic fertilizer production (OFP)—for their effects on antibiotic-resistant bacteria, antibiotic resis-tance genes, and microbial community diversity in the treated manures.
Jul 8, 2019 · In β-lactam resistance genes, the strongest relationships were demonstrated between blaOXA1 and compost days (P=0.016), and the removal rate was 78.63%. The average removal rate was 90.39% for amide resistance genes, which decreased significantly with composting time. The removal ratios were different among tetracycline resistance genes.
Apr 20, 2021 · Agricultural soils are often amended with livestock manure, making them a key reservoir of antibiotic resistance genes (ARGs). Given that soils are among the most microbially-diverse environments on the planet; effective characterization and quantification of the effects of manure-derived amendments
Sep 1, 2021 · Aerobic composting is commonly used to dispose livestock manure and is an efficient way to reduce antibiotic resistance genes (ARGs). Here, the effects of different quality substrates on the fate of ARGs were assessed during manure composting. Results showed that the total relative abundances of ARG
Jan 15, 2018 · Aerobic composting significantly reduced the diversity and abundance of resistome in cattle manure. •. The diversity and abundance of ARGs in manure-treated soils were significantly higher than in compost-treated soils. •. More intensive associations among ARGs and MGEs were found in manure-treated soils than in compost-treated soils. •.
enhanced corrosion resistance large scale composting Large-Scale Organic Materials Composting - NC State Extension 2 days ago · Once they’re converted into compost, organic wastes—which are the compostable portions of the solid waste stream—can be used to mulch landscaping, enhance crop growth, enrich topsoil, and provide other benefits.
Jan 16, 2023 · Chop the leaves into small pieces and place them in a compost bin. Add a layer of soil, followed by a layer of manure. Add water to the bin until the mixture is damp but not soggy. Turn the mixture regularly, making sure to mix the layers. Monitor the temperature inside the compost bin.
Mar 1, 2009 · The objectives of the 18-wk trial were to quantitatively assess the survival of total E. coli, E. coli resistant to ampicillin (Amp r) and tetracycline (Tet r), and select tetracycline (tet) and erythromycin resistance methylase (erm) genes.
