“…When the initial concentration is 25, 50, 100, 150, and 200 mg/ L, the removal rates of SMX by SRB sludge through adsorption and biodegradation are 3.9, 5.6, 13.2, 15.9, and 21.3 mg/L/d 15 . Other bacteria, including Achromobacter denitrificans PR1 16 , P. chrysosporium 17 , Pseudomonas stutzeri 18 , and Acinetobacter sp. 19 , could serve as resources for the bioremediation of SMX from the polluted environment.…”

Sulfamethoxazole (SMX) is the most commonly used antibiotic in worldwide for inhibiting aquatic animal diseases. However, the residues of SMX are difficult to eliminate and may enter the food chain, leading to considerable threats on human health. The bacterial strain Sphingobacterium mizutaii LLE5 was isolated from activated sludge. This strain could utilize SMX as its sole carbon source and degrade it efficiently. Under optimal degradation conditions (30.8 °C, pH 7.2, and inoculum amount of 3.5 × 107 cfu/mL), S. mizutaii LLE5 could degrade 93.87% of 50 mg/L SMX within 7 days. Four intermediate products from the degradation of SMX were identified and a possible degradation pathway based on these findings was proposed. Furthermore, S. mizutaii LLE5 could also degrade other sulfonamides. This study is the first report on (1) degradation of SMX and other sulfonamides by S. mizutaii, (2) optimization of biodegradation conditions via response surface methodology, and (3) identification of sulfanilamide, 4-aminothiophenol, 5-amino-3-methylisoxazole, and aniline as metabolites in the degradation pathway of SMX in a microorganism. This strain might be useful for the bioremediation of SMX-contaminated environment.

“…In contrast, the pathways of solid electron shuttles for enhanced antibiotic removal are more abundant. Mainly, (1) carbon-based and metal-based materials cast into anaerobic systems, especially in wastewater treatment, serve as good carriers for microbial growth and can significantly improve microbial growth activity ( Zhao Z. S. et al, 2020 ; Yang et al, 2021a ); (2) antibiotics in the aqueous phase are adsorbed onto the surface of the electron shuttle by adsorption ( Zhao Z. S. et al, 2020 ; Cheng et al, 2021 ), due to their excellent electrical conductivity acting as an microbial-antibiotic “electron bridge” to enhance the electron transfer process ( Zhang Z. H. et al, 2018 ; Zhou et al, 2021c ); (3) the pili and cytochrome C of bacteria are important mediators of the microbial extracellular electron transfer process. It has been pointed out that metal oxides (e.g., Fe 3 O 4 , MnO 2 ) help to stimulate the expression of relevant functional genes and promote them with different effects ( Xiao et al, 2022 ).…”

The environmental and epidemiological problems caused by antibiotics and antibiotic resistance genes have attracted a lot of attention. The use of electron shuttles based on enhanced extracellular electron transfer for anaerobic biological treatment to remove widespread antibiotics and antibiotic resistance genes efficiently from wastewater or organic solid waste is a promising technology. This paper reviewed the development of electron shuttles, described the mechanism of action of different electron shuttles and the application of enhanced anaerobic biotreatment with electron shuttles for the removal of antibiotics and related genes. Finally, we discussed the current issues and possible future directions of electron shuttle technology.

“…Chloramphenicol is a broad spectrum antibiotic intensively used in clinical practice, it is as an effective bacteriostatic antimicrobial for diverse bacteria (Liang et al, 2013;Zhang et al, 2020). The intensive use of chloramphenicol is of increasing concern due to its mutagenic, carcinogenic and toxic effects, notably for hematopoietic and digestive system in humans and animals (Deng et al, 2017;Yang et al, 2020a). Nonetheless, chloramphenicol is still widely used in many developed countries due to its low manufacturing cost and extensive availability (Boeckx and Brett;.…”

Electroactive microorganisms and electrochemical technologies have been separately used for environmental remediation such as antibiotics removal, yet the efficiency of coupling these two methods for chlorinated antibiotics removal is poorly known. Here we tested the synergy of Geobacter sulfurreducens PCA, an electroactive bacteria, and an electrical field, on chloramphenicol removal. Removal is increased two-fold by increasing the temperature from 30 • C to 37 • C. The cyclic voltammograms and chronoamperometry tests demonstrated that G. sulfurreducens PCA catalyzed chloramphenicol chemical reduction with electrode as excusive electron donor. A critical voltage, − 0.6 to − 0.5 V vs. Ag/AgCl, was discovered for chloramphenicol degradation with an increase of removal rate about 2.62-folds, from 31.06% to 81.41%. Combined removal with both G. sulfurreducens PCA and an electrical field increased the apparent rate constant and reached 82.77% removal at − 0.5 V. Specially, the combined removal at − 0.5 V even presented more robust removal efficiency compared to − 0.6 V (78.64%) without G. sulfurreducens PCA. Mass spectrometry of degradation products indicates the reduction of nitro into amine groups, and dechlorination into less toxic compounds. Overall, combined biocatalysis and an electrical field is a promising method to remove antibiotics from polluted environments.
