“…With a continuous increase in antibiotic usage in the livestock industry, consideration of the type and concentration of antibiotics used is important. Not only AMX but various other antibiotics are used, including tetracyclines, quinolones, penicillin, cephems, ionophores, and sulfonamide [66][67][68]. Investigating the detailed interactions between these antibiotics and microalgal growth, as well as optimizing the conditions of cultivation, is essential.…”

The residual antibiotics in livestock excreta (LE) have been regarded as a potential threat to the ecosystem and human society. Some photoautotrophic microalgae, however, were found to metabolize them during active biomass photosynthesis. This study investigates how the strength of the antibiotics impacts the overall biodiesel yield and composition of the harvested microalgal biomass grown from LE. The microalgal growth results demonstrate that increasing the concentration of residual antibiotics suppresses the microalgal growth rate from 0.87 d−1 to 0.34 d−1. This 61% lower biomass production rate supports the proposition that the kinetic impact of antibiotics may slow lipid synthesis. Moreover, the analytical results of fatty acid methyl ester (FAME) demonstrate that amoxicillin substantially reduces the C16:0 content by over 96%. This study evidences that the functional group similarity of amoxicillin may competitively inhibit the esterification reaction by consuming methanol. This explanation further highlights that residual antibiotics interfere with microalgal lipid synthesis and its transesterification. Moreover, it was confirmed that the presence of residual antibiotics may not affect the major nutrient removal (total nitrogen: 74.5~78.0%, total phosphorus: 95.6~96.8%). This indicates that residual antibiotics inhibit the metabolism associated with carbon rather than those associated with nitrogen and phosphorus, which is connected to the decrease in the biodiesel yield. Overall, these results reveal that the frequent abuse of antibiotics in livestock may harm the eco-friendly conversion of waste-into-bioenergy strategy.

“…In countries with advanced agricultural practices, such as the Netherlands and Belgium, pig manure is primarily sprayed on farmland to be used as a nutrient for crops [11,12]. Pig manure is rich in nutrients such as nitrogen and phosphorus [13] and thus can be utilized as a nutrient source for crops [14] and a soil amendment [9,12].…”

This study was conducted to examine the operation statuses of on-site swine wastewater treatment facilities through surveys and field surveys on pig farms and to propose effective operation models. Field analyses and surveys of pig farms indicate that technical and financial support systems are required for both farms and on-site swine wastewater treatment facilities. Public environmental services have been proposed as an effective support system, in which private sewage treatment facilities are entrusted to professional environmental management agencies, and the costs are shared by local governments and facility owners. However, securing a stable budget represents a challenge to implementing public environmental services. Thus, this study proposes a collaborative manure management model composed of individual farms, professional environmental management agencies, and local governments to address the shortcomings of public environmental services. To effectively manage pig manure, the flexible application of discharge standards, diversification of pollutant reduction management techniques (e.g., feed management), and periodic review of permits must be considered. Additionally, the reinforcement of discharge standards for individual purification facilities, control of the livestock density and number, and impacts of livestock manure discharge on riverine ecosystems must be considered.

“…Antibiotics are deemed indispensable for the protection of human life, and both their production and usage continue to increase steadily [1][2][3]. Furthermore, the consumption of meat has increased with the improved standards of living, and thus livestock breeding facilities have been scaled up in numerous regions to meet the growing demand [2,4,5]; consequently, considerable quantities of antibiotics are being used to prevent and treat diseases of livestock and to promote growth. According to the Korea Health Industry Development Institute, the quantity of national antibiotic production has continuously increased, and the market size was estimated at approximately KRW 1.1 trillion (USD ~950 million) in 2015 [1,6].…”

“…Substantial amounts of antibiotics consumed by humans or those administered to livestock during breeding are discharged into the environment via excreta through various routes such as compost, liquid manure, and runoff from breeding facilities. Subsequently, such antibiotics flowing into the environment have emerged as a new global concern due to their potential adverse effects [4,8]. Many studies have suggested that antibiotics present at concentrations of several ng•L −1 to µg•L −1 can inhibit the growth of aquatic organisms, plants, and humans [9][10][11].…”

“…Globally, the standards for the analysis and management of residual antibiotics in environmental media are insufficient; thus, it is necessary to evaluate their status [2][3][4]. The concentrations of antibiotics in the environment are known to be affected by various factors such as the pollution source, geography, climate, and usage patterns [3,15,16]; therefore, it is crucial to monitor and analyze residual antibiotics in environmental media across space and time to understand their statuses in different watersheds and to establish efficient management methods to mitigate their environmental effects.…”

Antibiotics used for the treatment of humans and livestock are released into the environment, whereby they pose a grave threat to biota (including humans) as they can cause the emergence of various strains of resistant bacteria. An improved understanding of antibiotics in the environment is thus vital for appropriate management and mitigation. Herein, surface water and groundwater samples containing antibiotics were analyzed in an urban–rural complex watershed (Cheongmi Stream) comprising intensive livestock farms by collecting samples across different time points and locations. The spatiotemporal trends of the residual antibiotics were analyzed, and ecological and antibiotic resistance-based risk assessments were performed considering their concentrations. The results showed that the concentrations and detection frequencies of the residual antibiotics in the surface water were affected by various factors such as agricultural activities and point sources, and were higher than those found in groundwater; however, frequent detection of antibiotics in groundwater showed that residual antibiotics were influenced by factors such as usage pattern and sewage runoff. Furthermore, few antibiotics posed ecological risks. The risk assessment methods adopted in this study can be applied elsewhere, and the results can be considered in the environmental management of residual antibiotics in the Cheongmi Stream watershed.
