“…Previous studies have also reported that antibiotic pollution could alter the N-cycling process ( Wu J. et al, 2022 ). For example, sulfadiazine inhibits functional genes related to denitrification and anaerobic ammonium oxidation in sediments ( Wang M. et al, 2023 ; Wang X. et al, 2023 ). As well as, nitrifier-denitrification rates were inhibited by sulfamethoxazole ( Chen et al, 2022 ).…”

“…We aimed to identify the major N-cycling gene families and their key environmental factors. A shotgun metagenome sequencing approach was applied to survey 6 important N-cycling processes and related functional genes ( Supplementary Text S1 ): 1) nitrogen fixation (e.g., nifH, nifD, nifK, vnfG, and vnfH ) ( Jiang et al, 2022 ; Li et al, 2022 ); 2) nitrification (e.g., amoA, amoB, amoC, and hao ) ( Wang et al, 2022 ; Liao et al, 2023 ); 3) denitrification (e.g., nirB, nirS, norC, narI and nirK, and nosZ ) ( Waldrop et al, 2023 ); 4) DNRA (e.g., napA, napB, narG, narH, narI, nrfH, nrtA, nirB, nirD, and nrfA ) ( Jiang et al, 2023 ; Waldrop et al, 2023 ); 5) ANRA (e.g., nasA, nasD, nirA, and nasE ) ( Hu et al, 2023 ; Li et al, 2023 ); and 6) anammox (e.g., nirK and nirS ) ( Tu et al, 2017 ; Wang M. et al, 2023 ; Wang X. et al, 2023 ).…”

“…After these organisms die, they release a large amount of organic nitrogen and inorganic nitrogen to water and sediments ( Li et al, 2012 ; Wu et al, 2021 ). In eutrophic lakes, the microbial decomposition of a large number of dead aquatic organisms settling to the bottom of the lakes can cause a lower concentration of dissolved oxygen ( Wu et al, 2021 ), which will lead to the production of ammonia, sulfide and other substances ( Hu et al, 2023 ), having a negative impact on the lake ecosystem health ( Wang M. et al, 2023 ; Wang X. et al, 2023 ).…”

N-cycling processes mediated by microorganisms are directly linked to the eutrophication of lakes and ecosystem health. Exploring the variation and influencing factors of N-cycling-related genes is of great significance for controlling the eutrophication of lakes. However, seasonal dynamics of genomic information encoding nitrogen (N) cycling in sediments of eutrophic lakes have not yet been clearly addressed. We collected sediments in the Baiyangdian (BYD) Lake in four seasons to explore the dynamic variation of N-cycling functional genes based on a shotgun metagenome sequencing approach and to reveal their key influencing factors. Our results showed that dissimilatory nitrate reduction (DNRA), assimilatory nitrate reduction (ANRA), and denitrification were the dominant N-cycling processes, and the abundance of nirS and amoC were higher than other functional genes by at least one order of magnitude. Functional genes, such as nirS, nirK and amoC, generally showed a consistent decreasing trend from the warming season (i.e., spring, summer, fall) to the cold season (i.e., winter). Furthermore, a significantly higher abundance of nitrification functional genes (e.g., amoB, amoC and hao) in spring and denitrification functional genes (e.g., nirS, norC and nosZ) in fall were observed. N-cycling processes in four seasons were influenced by different dominant environmental factors. Generally, dissolved organic carbon (DOC) or sediment organic matter (SOM), water temperature (T) and antibiotics (e.g., Norfloxacin and ofloxacin) were significantly correlated with N-cycling processes. The findings imply that sediment organic carbon and antibiotics may be potentially key factors influencing N-cycling processes in lake ecosystems, which will provide a reference for nitrogen management in eutrophic lakes.

“…Related studies have shown that heavy metals can combine with antibiotics in compound pollution [ 13 ], synergistic selection pressure between heavy metals and antibiotics increases the population of co-resistant microorganisms in the environment, impairs microbial communities and the expression of genes that function in the nitrogen cycle, and affects microorganisms in the marine environment, causing changes in the structure and diversity of natural microbial communities and affecting the ecological environment [ 14 ].…”

Antibiotics and heavy metals have caused serious contamination of the environment and even resulted in public health concerns. It has therefore become even more urgent to adopt a sustainable approach to combating these polluted environments. In this paper, we investigated the microbial community of marine sediment samples after 255 days of enrichment culture under Cu (II) and lincomycin stress and ZC255 was the most resistant strain obtained. The 16S rRNA gene sequence confirmed that it belonged to the genus Rossellomorea. Strain ZC255 was resistant to 12 kinds of antibiotics, and had a superior tolerance to Cu (II), Pb (II), Ni (II), Zn (II), Cr (III), and Cd (II). Moreover, it exhibits strong bioremoval ability of Cu and lincomycin. The removal efficiency of Cu (II) and lincomycin can achieve 651 mg/g biomass and 32.5 mg/g biomass, respectively. Strain ZC255 was a promising isolate for pollution bioremediation applications.

“…As is well known, nitrogen availability is closely related to the nitrogen metabolism, whereas it is restrained by antibiotics. For example, sulfadiazine inhibited nitrification functional genes and nitrobacteria in the surface sediment, resulting in NH 4 + and NO 2 − accumulation in overlying water [24]. The presence of oxytetracycline, sulfamethazine, and ciprofloxacin restrained urea decomposition and denitrification by reducing the abundance of functional genes, including ureC, nirK and norB, in soil [25].…”

Background Soil microbial fuel cells (MFCs) can remove antibiotics and antibiotic resistance genes (ARGs) simultaneously, but their removal mechanism is unclear. In this study, metagenomic analysis was employed to reveal the functional genes involved in degradation, electron transfer and the nitrogen cycle in the soil MFC. Results The results showed that the soil MFC effectively removed tetracycline in the overlapping area of the cathode and anode, which was 64% higher than that of the control. The ARGs abundance increased by 14% after tetracycline was added (54% of the amplified ARGs belonged to efflux pump genes), while the abundance decreased by 17% in the soil MFC. Five potential degraders of tetracycline were identified, especially the species Phenylobacterium zucineum, which could secrete the 4-hydroxyacetophenone monooxygenase encoded by EC 1.14.13.84 to catalyse deacylation or decarboxylation. Bacillus, Geobacter, Anaerolinea, Gemmatirosa kalamazoonesis and Steroidobacter denitrificans since ubiquinone reductase (encoded by EC 1.6.5.3), succinate dehydrogenase (EC 1.3.5.1), Coenzyme Q-cytochrome c reductase (EC 1.10.2.2), cytochrome-c oxidase (EC 1.9.3.1) and electron transfer flavoprotein-ubiquinone oxidoreductase (EC 1.5.5.1) served as complexes I, II, III, IV and ubiquinone, respectively, to accelerate electron transfer. Additionally, nitrogen metabolism-related gene abundance increased by 16% to support the microbial efficacy in the soil MFC, and especially EC 1.7.5.1, and coding the mutual conversion between nitrite and nitrate was obviously improved. Conclusions The soil MFC promoted functional bacterial growth, increased functional gene abundance (including nitrogen cycling, electron transfer, and biodegradation), and facilitated antibiotic and ARG removal. Therefore, soil MFCs have expansive prospects in the remediation of antibiotic-contaminated soil. This study provides insight into the biodegradation mechanism at the gene level in soil bioelectrochemical remediation.
