Apr 30, 2024 · Livestock manure is one of the most important pools of antibiotic resistance genes (ARGs) in the environment. Aerobic composting can effectively reduce the spread of antibiotic resistance risk in livestock manure. Understanding the effect of aerobic composting process parameters on manure-sourced ARGs is important to control their spreading risk. In this study, the effects of process
Sep 26, 2023 · The anaerobic fermentation experiment of pig manure showed that pH regulation had obvious effect on anaerobic fermentation of pig manure, and the effect of promoting fermentation followed acid
Jan 10, 2022 · In the present study, the mechanism and behavior of heavy metals passivation during the anaerobic fermentation of pig manure mixed with pretreated straw were investigated. The results showed that the alkali-treated straw enhanced the passivation rates of Cu and Zn. The anaerobic fermentation process could promote the migration of heavy metals into the biogas slurry, while the pretreated straw
Aug 1, 2020 · Recirculation was beneficial for biomethane production and digestion stability in digesters of corn stalk and straw/manure 3:1 by alleviating the loss of ammonia and alkalinity, while it aggravated the accumulation of ammonia and organic acids and reduced methane yield under 1:1, 1:3 and pig manure.
Pig manure is an important biomass resource, and anaerobic fermentation is one of the main ways to treat pig manure. However, the residual anaerobic fermentation slurry becomes a new pollutant; therefore, it is essential to study whether the anaerobic fermentation slurry could be used for soil anaerobic disinfection and enhance the efficiency of the process.
Jan 14, 2021 · (1) Objective: The objective of this study was to screen amoxicillin (AMX)-degrading bacterial strains in pig manure and optimize the fermentation conditions for these strains to achieve high fermentation rate, which can provide an effective way for the practical application of bacterial strains as antibiotic-degrading bacterial in treating livestock waste for antibiotic residues.
