2022/6/15/ · The detection of ARGs have been frequently occurred in livestock manure, which was much higher than in base of soil or the source water (Zhu et al., 2013).Livestock feces normally contains all the known ARGs (Guo et al., 2017; Zhu et al., 2013), and the ARGs abundance in untreated animal manure fluctuated between 10 6 and 10 11 copies·g −1 dry

2024/9/1/ · By comparing the sequence of inoculated bacteria and composting microorganisms, it was found that inoculated B. licheniformis colonized successfully in compost, and accounted for 44.0% of Bacillus. It was reported that Bacillus could secrete enzymes to accelerate organic degradation ( Ding et al., 2022 ), therefore same as the above analysis

2023/12/1/ · At the end of composting, the relative abundance of Chloroflexi in the nZVI group (10.88 %) was higher than that in the CK group (9.20 %). In general, the addition of BC-nZVI promoted the growth of beneficial bacteria in the composting system and regulated the microbial community structure in a positive direction.

2019/12/1/ · At present, the remediation ways of heavy metals in environment are mainly divided into two ideas. One way is to passivate heavy metals. Traditional passivation way of heavy metals is performed in compost, which includes microbial passivation and immobilization of organic macromolecules (e.g., humic acid and humin) produced during composting (Chen et

2022/9/1/ · A laboratory-scale composting system was used to perform two groups of composting experiments with chicken manure and sludge (triplicates in each group). The chicken manure and sludge were collected from a poultry farm and a wastewater treatment plant (Fuzhou, China), respectively.

2020/10/20/ · Due to the enhanced decomposing, nitrosation, and nitrification effect lead by the functional microorganism, treatment with the optimal MC (53%) exhibited the highest composting temperature (61 °C) and longest high-temperature period (15 days), achieving a final carbon-nitrogen ratio (C/N), humic acids and fulvic acids ratio (HA/FA), and NH 4

2010/8/15/ · A biotrickling filter (BTF) was used to treat NH 3 emitted from the exhaust gases of cattle manure compost. Results of the non-biofilm experiment suggested that NH 3 could not be removed effectively only through biofilm adsorption. The absence of NH 4 + bio-oxidation resulted in an increase in free ammonia, which had a negative effect on NH 3 removal. After biofilm

2023/6/1/ · Few studies on Bacillus inoculation have been reported for lignocellulose degradation and composts fertility during composting. This research explored the enhanced lignocellulose degradation and composts fertility of cattle manure and wheat straw composting by Bacillus inoculation. Bacillus methylotrophicus F-6, Bacillus velezensis T-B, and Bacillus

2024/4/1/ · Aerobic composting is widely studied and applied due to its benefits, such as reducing environmental pollution, lowering transportation costs, maintaining a clean operational environment, achieving high automation, and promoting resource utilization (Nguyen et al., 2020).Notably, the high-salt and high-oil diets in China contribute to higher levels of salt and oil …

2023/10/1/ · Based on the above assumption, an original and novel composting system, the condensation return composting system (CRCS), was designed. The aims of this study were 1) to assess the NH 3 mitigation and nitrogen retention capacity of the CRCS, 2) to clarify the mechanisms of nitrogen fraction conversion and nitrogen retention in the CRCS, and 3) to …
