Extracellular polymeric substances—antibiotics interaction in activated sludge: A review

Environmental Science and Ecotechnology, Journal Year: 2022, Volume and Issue: 13, P. 100212 - 100212

Published: Nov. 9, 2022

Antibiotics, the most frequently prescribed drugs, have been widely applied to prevent or cure human and veterinary diseases undoubtedly led massive releases into sewer networks wastewater treatment systems, a hotspot where occurrence transformation of antibiotic resistance take place. Extracellular polymeric substances (EPS), biopolymers secreted via microbial activity, play an important role in cell adhesion, nutrient retention, toxicity resistance. However, potential roles sludge EPS related removal antibiotics are still unclear. This work summarizes composition physicochemical characteristics state-of-the-art EPS, highlights critical removal, evaluates their defense performances under different exposures, analyzes typical factors that could affect sorption biotransformation behavior antibiotics. Next, interactions between genes analyzed. Future perspectives, especially engineering application for detection defense, also emphatically stressed.

Metabolite Cross-Feeding Promoting NADH Production and Electron Transfer during Efficient SMX Biodegradation by a Denitrifier and S. oneidensis MR-1 in the Presence of Nitrate

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(46), P. 18306 - 18316

Published: April 12, 2023

Antibiotics often coexist with other pollutants (e.g., nitrate) in an aquatic environment, and their simultaneous biological removal has attracted widespread interest. We have found that sulfamethoxazole (SMX) nitrate can be efficiently removed by the coculture of a model denitrifier (Paracoccus denitrificans, Pd) Shewanella oneidensis MR-1 (So), SMX degradation is affected NADH production electron transfer. In this paper, mechanism promoting transfer was investigated proteomic analysis intermediate experiments. The results showed glutamine lactate produced Pd were captured So to synthesize thiamine heme, released taken up as cofactor pyruvate ketoglutarate dehydrogenase, which related generation. Additionally, acquired facilitated important composition complex III cytochrome c iron source sulfur clusters, key component I chain. Further investigation revealed generated prompted chemotactic moving toward Pd, helped two bacteria effectively obtain required substances. Obviously, metabolite cross-feeding promoted transfer, resulting efficient biodegradation presence nitrate. Its feasibility finally verified activated sludge So.

Inactivation of antibiotic-resistant bacteria and antibiotic-resistance genes in wastewater streams: Current challenges and future perspectives

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 13

Published: Jan. 16, 2023

The discovery of antibiotics, which was once regarded as a timely medical intervention now leaves bitter aftertaste: antimicrobial resistance (AMR), due to the unregulated use these compounds and poor management receiving wastewaters before discharge into pristine environments or recycling such treated waters. Wastewater treatment plants (WWTPs) have been central sink for mostly unmetabolized partially metabolised antibiotics is also pivotal incidence antibiotic bacteria (ARBs) their genes (ARGs), consistently contribute global disease burden deteriorating prophylaxis. In this regard, we highlighted WWTP-antibiotics consumption-ARBs-ARGs nexus, might be critical understanding epidemiology AMR guide precise prevention remediation occurrences. We discovered unsophistication conventional WWTPs techniques adequate ARBs ARGs, lack compliance with environmental sustainability, then ultimately assessed prospects cold atmospheric plasma (CAP). Herein, observed that CAP technologies not only has capability disinfect wastewater polluted copious amounts chemicals biologicals, but potential augment bioelectricity generation, when integrated bio electrochemical modules, future should retrofitted accommodate. Therefore, further research conducted unveil more unknowns, snippet in study.

Environmental Antimicrobial Resistance: Implications for Food Safety and Public Health

Antibiotics, Journal Year: 2024, Volume and Issue: 13(11), P. 1087 - 1087

Published: Nov. 14, 2024

Antimicrobial resistance (AMR) is a serious global health issue, aggravated by antibiotic overuse and misuse in human medicine, animal care, agriculture. This study looks at the different mechanisms that drive AMR, such as environmental contamination, horizontal gene transfer, selective pressure, well severe implications of AMR for health. demonstrates need concerted efforts across scientific, healthcare, agricultural, policy sectors to control emergence AMR. Some crucial strategies discussed include developing antimicrobial stewardship (AMS) programs, encouraging targeted narrow-spectrum use, emphasizing significance strict regulatory frameworks surveillance systems, like Global Resistance Use Surveillance System (GLASS) Access, Watch, Reserve (AWaRe) classification. also emphasizes national international action plans combating promotes One Health strategy, which unifies environmental, animal, concludes preventing spread maintaining effectiveness antibiotics future generations requires comprehensive, multidisciplinary, internationally coordinated strategy.
