Dec 1, 2022 · Industrial-scale aerobic composting of livestock manures with the addition of biochar: Variation of bacterial community and antibiotic resistance genes caused by various composting stages
Mar 1, 2020 · •. Bacterial community and BMRGs profiles structured the antibiotic resistome. Abstract. Composting has been widely used to turn livestock manure into organic fertilizer. However, livestock manure contains various contaminants including antibiotics and antibiotic resistance genes (ARGs).
The findings revealed that the use of compound microbial inoculants increased the compost temperature, accelerated moisture reduction, enhanced cellulase activity, and stimulated the accumulation of NH 4 +-N, NO 3--N, and total nitrogen (TN), resulting in a 9% increase in TN content. The abundance of Firmicutes decreased by 3.95% at the
Apr 15, 2021 · In another composting experiment conducted by Chang et al. (2019a), it has been reported that SRGs (sul1 and sul2) were overwhelmingly increased from 1.2 × 10 8 to 1.2 × 10 11 copies per gram of dry compost. In chicken manure composting, the absolute abundance of several ARGs (e.g., tetQ, cmlA, and floR) were significantly increased in some
Dec 7, 2023 · Enhanced corrosion and wear resistance of Zn–Ni/Cu–Al 2022/11/21/ · In order to improve the cathodic protection and wear resistance of cold spraying Zn-based coatings, Zn–Ni/Cu–Al2O3 composite coating was prepared by co-depositing Zn powders, nickel-coated Cu powders, and Al2O3 powders on the steel substrate using the low
Feb 15, 2018 · Aerobic composting is used widely for animal manure recycling, and it may reduce the amount of antibiotic resistance genes (ARGs) that enter the environment. We sampled three types of animal (bovine, chicken, and pig) manure and the corresponding composts from 12 large-scale farms, and tested multiple ARGs and mobile genetic elements (MGEs) by
Mar 21, 2021 · While the Shannon diversity varied between manure compost types, the diversity of sheep and cattle manure composts were significantly higher compared to pig and chicken manure composts at both composting phases (bacteria: F 1,23 = 12.5, P = 0.002; fungi: F 1,23 = 6.07, P = 0.022, Figures 2A,B).
May 3, 2022 · In the present investigation the effects of biochar and hyper-thermal inoculum on the heavy-metal-resistant bacteria (HMRB) during livestock manure composting were studied. An experiment was performed on composting livestock manure and wheat straw amended with biochar and hyper-thermal inoculum. Physicochemical properties, enzyme activity, heavy metals (HMs), and bacterial activities were
4 Best Compost Machines for Beginner Composters - GreenCitizen. This Countertop Compost Machine Turns Scraps into Compost in . Mar 27, 2024 · The Lomi countertop compost machine makes turning kitchen scraps into compost the easiest thing ever.
Turning manure is essential to composting manure. Turning compost incorporates oxygen into the system, homogenizes the pile and breaks up clumps. Turning allows more contact of manure with microbes. Producers have various ways to turn the pile. The two most common for turning compost are with a windrow turner (Figure 7) or bucket tractor.
Although composting has many advantages in treating livestock manure, in the traditional aerobic composting of livestock manure, the compost temperature must be higher than 50°C, and the duration should be 5–10 days to meet the requirements of harmless sanitation of manure . Moreover, sometimes due to organic waste's physio-chemical
Jul 21, 2023 · This study was designed to investigate the efficiency of improved composting equipment in enhancing the composting process of livestock manure. The optimized equipment addresses issues of poor mixing effect, low automation level, and extended composting cycles in traditional composting .
Mar 19, 2019 · Review on the removal of antibiotic resistance genes from livestock manure by composting total pore volume: 0.2451 m³/g), which markedly enhanced soil heterogeneity that created a barrier to ...
Jan 14, 2022 · Co-composting of paddy straw with cattle manure, farmyard manure and poultry manure. Inoculated with Aspergillus niger ITCC 6719, Aspergillus flavus ITCC 6720 and Trichoderma harzianum ITCC 6721.
The International Livestock Expo – ILDEX PHILIPPINES 2025 is set to take place from August 27–29 at the SMX Convention Center in Manila, Philippines! Henan Bolong will showcase its core equipment and livestock manure solutions at Booth No. C11.
Traditional manure composting is prone to complaints and environmental fines due to the decomposition of organic matter, uncontrolled fermentation environment and unsealed diffusion.Bolong sealed composting tank blocks odor at the source of the sealed tank and removes odor at the end of the spray tower (with an efficiency of over 95%), combined with high-temperature aerobic fermentation to inhibit odor-producing bacteria, effectively solving the odor problem. Mature manure can be directly used as fertilizer or sold to increase income, suitable for large-scale farms, and can be quickly matured to meet standards in 7 days. The equipment helps farms comply with environmental regulations and avoid penalties, and intelligent control reduces costs and increases efficiency, achieving odor elimination and turning waste into treasure.
