Jun 13, 2023 · resistant nitrifying bacteria from compost samples, then was inoculated into sewage sludge composting, compared with the control, the compost quality was improved and the ammonia emission was reduced by 29.7%. Yu et al. [52] inoculated lignocellulose-degrading microorganisms in chicken manure compost improved the metabolic activ -
May 20, 2020 · In the present study, anaerobically digested chicken manure and various types of c Composting and anaerobic digestion techniques are widely used for manure recycling, but these have shown conflicting results in the removal of antibiotics, antibiotic resistance genes (ARGs), and heavy metals.
Apr 11, 2023 · Organic waste management is an important concern for both industries and communities. Proper management is crucial for various reasons, such as reducing greenhouse gas emissions, promoting sustainability, and improving public health. Composted manure is a valuable source of nutrients and organic matter that can be used as a soil amendment in agriculture. Some important benefits of using
Jul 15, 2023 · High temperatures kill pathogenic bacteria and drug-resistant microorganisms in livestock manure and degrade most antibiotics in animal manure [7]. In addition, composting can effectively mitigate the complex contamination of antibiotics and drug-resistant genes in manure by changing the composition and structure of microbial communities, which
Jun 1, 2023 · Cattle manure and wheat straw are high content of lignocellulose, which is polymeric organic matter resulting in resistance to microbial degradation [13]. Lignocellulose plays a key role in determining the maturation process of composting [30].
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
Feb 1, 2022 · However, how microbial community respond to heavy metals stress was rarely studied, which just studied the role of microorganisms. Previous study revealed the functional role of microorganisms to heavy metals during composting, which was defined as sensitive, resistant and actor (Chen et al., 2020b). Meanwhile, the basic theory of microbial
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
Aug 11, 2022 · Background Antibiotics and antibiotic resistance genes (ARGs) used in intensive animal farming threaten human health worldwide; however, the common resistome, ARG mobility, and ARG host composition in different animal manures and mixed manure composts remain unclear. In the present study, metagenomic assembly and cross-sample mapping were used to comprehensively decipher the common resistome
Dec 1, 2021 · However, fertilising effects of manure and its influence on soil biodiversity are highly dependent on its chemical composition, which varies based on animal feed and species (Kerr et al., 2006) and treatment/processing (Jørgensen and Jensen, 2009; Risberg et al., 2017).
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
Jun 14, 2016 · The composting of manure results in a product that is more nutrient-stable and free of microbial pathogens and phytotoxins [ 9 ]. Furthermore, composting may also decrease the concentration of excreted antimicrobials, resistance determinants, and resistant bacteria [ 10 – 12 ].
Mar 5, 2021 · Review on the fate of antimicrobials, antimicrobial resistance genes, and other micropollutants in manure during enhanced anaerobic digestion and composting J Hazard Mater . 2021 Mar 5:405:123634. doi: 10.1016/j.jhazmat.2020.123634.
