Sulfonamides are applied worldwide as antibiotics. They emerging contaminants of concern, their presence in the environment may lead to spread antibiotic resistance genes. present groundwater systems, which suggest persistence under certain conditions, highlighting importance understanding natural attenuation processes groundwater. Biodegradation is an essential process, degradation sulfonamides reduces risk spreading. In this review, attenuation, and particular assessment biodegradation, evaluated for systems. The current knowledge level on biodegradation reviewed, a scientific foundation built based sulfonamide processes, pathways, metabolites toxicity. An overview bacterial species related provided. main research effort has focused aerobic conditions while investigations anaerobic lacking. implementation laboratory scale; here we strived bridge towards field application assessment, by assessing approaches commonly used monitored attenuation. Methods document contaminant mass loss assessed be applicable sulfonamides, approach limited lack reference standards metabolites. Furthermore, additional information required relevant order improve assessments. Based it suggested use substituent-containing from breakage specific indicators degradation. Microbial currently available microbial community's capacities, however, more indigenous bacteria capable degrading impact environmental biodegradation. Compound stable isotope analysis shows great potential situ method, but further developments analyse at environmentally levels. Finally, scheme that can uncover some fate Nevertheless, there still unknowns well effect settings such redox conditions. Alongside, uncovering future research, applicability documentation will advance, provide step remedial concepts frequently detected sulfonamides.

Division of labor for substrate utilization in natural and synthetic microbial communities

Current Opinion in Biotechnology, Год журнала: 2022, Номер 75, С. 102706 - 102706

Опубликована: Март 4, 2022

In natural ecosystems, microorganisms live in communities where each member interacts with the others and environment to efficiently utilise available resources. Division of Labor (DOL) is an evolutionary strategy that evolved by microbial accomplish complex tasks. Current bio-based technologies could also benefit from DOL construct robust cell factories expanded metabolic capabilities. Here, we review some remarkable examples how used consortia utilize a range substrates. Also, most recent studies towards engineering design synthetic for efficient substrate utilization bioproduction.

Sulfonamide-metabolizing microorganisms and mechanisms in antibiotic-contaminated wetland sediments revealed by stable isotope probing and metagenomics

Environment International, Год журнала: 2022, Номер 165, С. 107332 - 107332

Sulfonamide (SA) antibiotics are ubiquitous pollutants in livestock breeding and aquaculture wastewaters, which increases the propagation of antibiotic resistance genes. Microbes with ability to degrade SA play important roles dissipation, but their diversity degradation mechanism field remain unclear. In present study, we employed DNA-stable isotope probing (SIP) combined metagenomics explore active microorganisms mechanisms biodegradation antibiotic-contaminated wetland sediments. DNA-SIP revealed various SA-assimilating bacteria dominated by members Proteobacteria, such as Bradyrhizobium, Gemmatimonas, unclassified Burkholderiaceae. Both sulfadiazine sulfamethoxazole were dissipated mainly through initial ipso-hydroxylation, driven similar microbes. sadA gene, encodes an NADH-dependent monooxygenase, was enriched 13C heavy DNA, confirming its catalytic capacity for ipso-hydroxylation addition, some genes encoding dioxygenases also proposed participate hydroxylation aromatic ring cleavage based on analysis, might role metabolism sediment ecosystem when Proteobacteria dominant bacteria. Our work elucidates ecological uncultured natural habitats gives a deeper understanding in-situ mechanisms.

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, Год журнала: 2023, Номер 57(46), С. 18306 - 18316

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.
