“…Several studies have reported their presence in receiving rivers after discharge from treatment plants, and their elimination during water treatment processes remains a challenge. Recently, Song et al assessed the potential of atmospheric pressure plasmas to inactivate ARB and to destroy ARGs using a plasma bubble discharge and antibiotic-resistant Escherichia coli (AR E. coli ) as a model ARB [ 30 ]. The results showed that a higher plasma voltage increased the inactivation of AR E. coli.…”

“…Plasma is a reactive cocktail of various reactive oxygen and nitrogen species, such as hydrogen peroxides, hydroxyl radicals, ozone, nitric oxide, UV photons, and charged particles such as electrons and ions, which are responsible for the inactivation of microorganisms [ 26 ]. Several pilot-scale studies focusing on the decontamination capacities of plasmas have been carried out with samples from municipal wastewater treatment plants (WWTPs) [ 27 , 28 , 29 , 30 , 31 , 32 ]. A large and growing body of literature reports the effective inactivation capacity of NTAPP for a wide range of microorganisms.…”

Bacterial resistance to antibiotics has become a major public health problem in recent years. The occurrence of antibiotics in the environment, especially in wastewater treatment plants, has contributed to the development of antibiotic-resistant bacteria (ARB) and the spread of antibiotic resistance genes (ARGs). Despite the potential of some conventional processes used in wastewater treatment plants, the removal of ARB and ARGs remains a challenge that requires further research and development of new technologies to avoid the release of emerging contaminants into aquatic environments. Non-thermal atmospheric pressure plasmas (NTAPPs) have gained a significant amount of interest for wastewater treatment due to their oxidizing potential. They have shown their effectiveness in the inactivation of a wide range of bacteria in several fields. In this review, we discuss the application of NTAPPs for the degradation of antibiotic resistance genes in wastewater treatment.

“…To fight against AR E. coli of animal origin, some traditional and novel strategies, including ultraviolet (UV) treatment, surface plasma oxidation, and biochar, have been reported to effectively kill AR E. coli by inhibiting DNA replication and destroying the cell membrane [ 30 , 31 , 32 ]. A few ARGs (including tetC , tetW , bla TEM-1 , ampC , etc.)…”

“…A few ARGs (including tetC , tetW , bla TEM-1 , ampC , etc.) of E. coli of animal origin were remarkably removed or reduced after plasma or biochar oxidation treatment, and conjugative transfer of ARGs (such as integron gene- intI1 ) was dramatically inhibited [ 31 , 33 ]. The advantage of using these methods is that they display high efficiency, simple equipment, and no/low exogenous chemical residues [ 30 , 33 , 34 ].…”

Escherichia coli is one of the most frequent causes of gastro-intestinal and extra-intestinal diseases in animals and humans. Due to overuse and misuse of antibiotics, recent years have seen a rapidly increasing prevalence of antibiotic-resistant (AR) Escherichia coli globally; particularly, AR E. coli from farm animal-associated sources and its antibiotic resistance genes (ARGs) are becoming a global concern, with clinical negative effects on both human and animal health. The aim of this review was to explore the prevalence trends of AR E. coli from farm animals, waste treatment, and aquatic environments. The disinfection methods of AR E. coli and possible alternatives to antibiotics were also highlighted. The current review highlights that the prevalence of AR E. coli from food animals, products, and animal waste is increasing at an alarming rate, but is reduced at waste treatment plants. Ultraviolet (UV) treatment, surface plasma oxidation, and biochar are commonly used to effectively eliminate AR E. coli. Some probiotics, plant extracts, and antimicrobial peptides (AMPs) are arousing interest as promising alternatives to antibiotics to fight against AR E. coli. The current review suggests that AR E. coli from farm animal-associated sources is prevalent and poses a serious global threat to public health. This review provides an avenue for further research, development, and application of novel strategies to minimize antibiotic resistance in E. coli of farm animal origin.

“…In addition, other actions such as a strong electric field and ultraviolet irradiation in the plasma process were also expected to synergistically promote microorganisms’ elimination . Some ordinary microorganisms were killed via the nonequilibrium plasma. − However, the ARGs probably transfer to other microorganisms although the ARB was inactivated, and thus they should be paid more attention. Recently, ARG and ARB removal was realized by the nonequilibrium plasma. , In these plasma processes, the strong oxidizing ROS were first produced in an air atmosphere (reactions –) , and then diffused into water to react with target pollutants.…”

The prevalence of various antibiotic-resistant bacteria (ARB) and antibiotic-resistance genes (ARGs) is becoming a global environmental problem. Removal of multiple resistant Escherichia coli strains, carrying a gentamicin resistance gene (aac(3)-II), an amoxicillin-resistance gene (blaTEM-1), tetracycline-resistance genes (tetC and tetW), and integron gene intI1, was investigated using a mesoporous plasma. The experimental results showed that the elimination efficiencies of integron intI1, aac(3)-II, blaTEM-1, tetW, and tetC reached 5.46, 5.71, 5.19, 2.88, and 2.28 log within 10 min of plasma oxidation, respectively. These elimination performances were positively related to the plasma intensity, duration time, and airflow rate. The cell membrane structures were significantly destroyed by the plasma oxidation, accompanied by leakage of ARG-containing DNA. Most of the ARG-containing DNA (more than 96%) was effectively damaged and decomposed to cytosine, guanine, adenine, and thymine. The present research revealed the removal behaviors of ARGs by plasma oxidation and provided an alternative to eliminate ARGs in an aqueous system.
