“…The control and elimination of antimicrobial resistance in agricultural fields are urgently needed [138]. The sewage treatment, composting or anaerobic digestion process of manure are some of the techniques that are used to reduce the concentrations of antimicrobials, ARGs and microorganisms that are introduced in soil through manure fertilization practices [139].…”

The increasing demand for animal-derived foods has led to intensive and large-scale livestock production with the consequent formation of large amounts of manure. Livestock manure is widely used in agricultural practices as soil fertilizer worldwide. However, several antibiotic residues, antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria are frequently detected in manure and manure-amended soils. This review explores the role of manure in the persistence and dissemination of ARGs in the environment, analyzes the procedures used to decrease antimicrobial resistance in manure and the potential impact of manure application in public health. We highlight that manure shows unique features as a hotspot for antimicrobial gene dissemination by horizontal transfer events: richness in nutrients, a high abundance and diversity of bacteria populations and antibiotic residues that may exert a selective pressure on bacteria and trigger gene mobilization; reduction methodologies are able to reduce the concentrations of some, but not all, antimicrobials and microorganisms. Conjugation events are often seen in the manure environment, even after composting. Antibiotic resistance is considered a growing threat to human, animal and environmental health. Therefore, it is crucial to reduce the amount of antimicrobials and the load of antimicrobial resistant bacteria that end up in soil.

“…With the expedited development of urbanization, the sewage treatment capacity is increasing year by year in China, which leads to large amounts of SS cannot be treated effectively in time 2,3 . China's urban SS is growing at a rate of 13% a year, with annual SS production expected to exceed 60 million tons by 2020, so the efficient and safe disposal of SS has become one of the main problems in China 4,5 . The urgency of SS treatment has been stressed in China's new environmental law and "The Prevention and Control Action Plan of Water Pollution" 6 .…”

“…That's because glucose and sucrose were easily used by microorganisms, and could participate in the biochemical reaction of composting faster. Moreover, the readily degradable carbon source could increase the DOC concentration (introduced in "Dissolved organic carbon and CO 2 emission") and improve the biodegradability of the carbon source, so more NH 4 + was converted to bio-nitrogen fixed in the compost.…”

“…3c, the NO 3 − concentrations of all the treatments were lower than the NH 4 + concentrations throughout the composting process, especially during mesophilic phase and thermophilic phase. The NO 3 − concentration was closely related to the activity of nitrifying microorganisms, but the activity of nitrifying microorganisms was inhibited by high temperature and high NH 4 + concentration, that's why the NO 3 − concentration were so low during the thermophilic phase. During the first 7 days of composting, the NO 3 − concentration of each treatment was at a low level (0.07-0.16 g/kg).…”

In present study, the effects of carbon sources on compost process and quality were evaluated in the lab-scale sewage sludge (SS) composting. The composting experiments were performed for 32 days in 5 L reactors. The results showed that carbon sources could change the nitrogen conversion and improve the compost quality. Especially, the readily degradable carbon source could promote organic matter degradation, improve nitrogen conversion process and accelerate compost maturation. The addition of glucose and sucrose could increase dissolved organic carbon, CO2 emission, dehydrogenase activity, nitrification and germination index during the SS composting. That's because glucose and sucrose could be quickly used by microbes as energy and carbon source substance to increase activity of microbes and ammonia assimilation. What's more, the NH3 emission was reduced by 26.9% and 32.1% in glucose and sucrose treatments, respectively. Therefore, the addition of readily degradable carbon source could reduce NH3 emission and improve compost maturity in the SS composting.
