“…In literature, chlorine has been reported that may lead to initially attack proteins and peptidoglycan bound to the cell wall and the cell membrane and, subsequently, penetrate into the cell wall to reach cytoplasm and react with nucleic acids [3,63]. Additionally, not only chlorine but also ozone has been recently reported for its ability to destroy ARGs [64][65][66]. Ozone reacts with bacterial functional groups, such as amines or amino acids, and also attacks proteins, peptidoglycan and liposaccharides in the cell envelope [67,68].…”

“…80 Xia et al used 25 mg/L O 3 to disinfect wastewater in a bioreactor and observed that the levels of multidrug, quinolone, mupirocin, polymyxin, aminoglycoside, glycopeptide, β-lactam, and trimethoprim resistance genes were reduced by more than 70%. 81 A more recent study used an O 3 concentration as high as 91 mg/L to disinfect wastewater from a high-speed railway train; five ARGs (tetA, tetG, qnrA, qnrS, bla NDM-1 ) were reduced by 1.67−2.49 log (an initial concentration of 4.35−7.78 log), and antibiotic-resistant enterococci was reduced by 3.16 log CFU/mL (an initial concentration of 6 log). 82 Another study summarized recent progresses on ozone application for enhanced wastewater treatment for chemical and biological contaminants, including DBP issues, elimination/disinfection efficiencies as a function of ozone doses or DOC normalized ozone dose.…”

The emergence of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment has created obstacles when treating infectious diseases with antibiotics. Wastewater treatment plants (WWTPs) serve as reservoirs for ARB and ARGs and can disseminate them into the environment. It is important to understand and address these risks. Generally, professional disinfection processes have been used in WWTPs to disinfect the target water body, with the goal of eliminating pathogenic microorganisms in the water. However, ARGs are not generally considered, and antibiotic resistance has spread and developed through horizontal gene transfer (HGT). This Review provides a detailed overview of the application progress of different traditional and new disinfection technologies in removing ARB and ARGs, mainly focusing on the bacterial inactivation mechanisms of chlorination, ozonation, ultraviolet (UV) (including UVA, UVB, and UVC), sunlight, sunlight-dissolved organic matter (DOM), and photocatalysis (PC)/photoelectrocatalysis (PEC). In addition, this Review also focuses on the disinfection technology involved in the transfer of ARGs and clarifies the underlying transfer mechanisms in water environments. Furthermore, by linking the mechanisms of bacterial inactivation, the Review describes how SOS response and cell membrane permeability may be the key step in the conjugation, transformation, and transduction of ARGs. Finally, given the applications and current problems associated with traditional water disinfection technologies and light-based disinfection technologies in removing and controlling ARB and ARGs, this Review describes the current challenges and opportunities to facilitate the development of future disinfection technologies. The Review also highlights future research directions related to ARG transmission control.

“…Nevertheless, commercializing PHA production at the industrial scale (i.e., using bioreactors) attracts business investments and a techno-environmental assessment opportunity and therefore, it must be performed. In addition to improving the wastewater treatment plants environmental performance, an evaluation should be done on the PHA production capacity/yield, life cycle analysis, carbon, nitrogen, and energy balance [100]. Several studies have evaluated the techno-environmental performance of different bioreactor configurations, and the following results were reported: Fungal chitosan produced from phenol and color containing wastewater during its treatment in a batch reactor.…”

Wastewaters from various process industries, namely food and agricultural, sugar mill, brewery, milk, vegetable and fruit, and meat and fisheries processing industries and their wastewater effluents contain nutrients, organic matter, inorganic, heavy metals, suspended solids, and pathogens. The discharges of non-treated wastewater enter the nearby aquatic ecosystem (e.g., lakes, rivers) and are a significant concern due to the presence of different nutrients, competing ions and C containing pollutants. It causes excessive growth of algae, loss of habitat/species, and other negative impacts on human health/environment. In the present review, different treatment approaches have been discussed in utilizing these nutrients to synthesize value-added products such as biopolymer, biofuel, pigment, organic acid, or enzymes. These biopolymers can be used to prepare various food products/packaging materials. Dextran, chitosan, carrageenan, alginate, and pectin are good examples of non-food biopolymers. Besides these products, poly-β-hydroxybutyrate (PHB) synthesis from wastewater nutrients is reported as a new source of bio-nanocomposite materials/biopolymer-based coatings. In this review, the different treatment approaches are discussed, which are being used worldwide for the removal/recovery of nutrients, toxic pollutants, and the potential resource recovery of value-added products from wastewater.
