“…By contrast, the previous work proved that Co(II) is the least inhibitory metal ion of Cu(II), Zn(II), Ni(II), and Co(II) in the nitrifying sludge, and the effect of Co(II) on bacteria is not crucial if the contact time with the biomass is short [42,43]. Nevertheless, Co(II) strongly inhibits the heterotrophic nitrification ability of strain Y-10, and even worse, it lost its denitrification ability once Co(II) was added to the wastewater.…”

The aim of this study was to investigate the possibility of a simultaneous nitrification–denitrification hypothermic bacterium for applying in Cd(II), Co(II), and Mn(II)-contaminated wastewater. The influence of Cd(II), Co(II), and Mn(II) on the inorganic nitrogen removal capacity of the hypothermia bacterium Arthrobacter arilaitensis Y-10 was determined. The experimental results demonstrated that low concentration of Cd(II) (2.5 mg/L) exhibited no significant impact on bioremediation of ammonium. The nitrate and nitrite removal activities of strain Y-10 were enhanced by 0.1 and 0.25 mg/L of Cd(II), but hindered by more than 0.25 and 0.5 mg/L of Cd(II), respectively. However, the cell growth and denitrification activity ceased immediately once Co(II) was supplemented. In terms of Mn(II), no conspicuous inhibitory impact on ammonium bioremediation was observed even if Mn(II) concentration reached as high as 30 mg/L. The bioremediation of nitrates and nitrites was significantly improved by 0.5 mg/L of Mn(II), and then dropped sharply along with the increase of Mn(II). The order of the degree of inhibitory influence of the three heavy metal ions on the nitrogen bioremediation ability of strain Y-10 was Co(II) > Cd(II) > Mn(II). All the results highlighted that the heterotrophic nitrification was less sensitive to the inhibitory effects of Cd(II), Co(II), and Mn(II) relative to aerobic denitrification.

“…to flocs effects on nitrification, considering that (1) the nitrifying communities are highly sensitive to the levels of both growth and non-growth substrates (Smith, 1964;Killham, 1990;Daims et al, 2016;Koch et al, 2019;Fujitani et al, 2020) and (2) when present in excess, many nutrients become toxic to the nitrifying community (Loveless and Painter, 1968;Liang and Tabatabai, 1977;Giashuddin and Cornfield, 1979;Cela and Sumner, 2002;Çeçen et al, 2010;Huang et al, 2016;Aslan and Sozudogru, 2017). However, the lack of established toxicity thresholds for soil nitrifiers makes definitive conclusions challenging.…”

“…In addition to Fe, Mo and Cu, other metals and nutrients may also influence nitrification, such as calcium (Ca), phosphorus (P), magnesium (Mg), nickel (Ni), cobalt (Co), manganese (Mn), zinc (Zn), aluminum (Al), and potassium (K) (Meiklejohn, 1952;Van Droogenbroeck and Laudelout, 1967;Loveless and Painter, 1968;Cela and Sumner, 2002;Çeçen et al, 2010;Bhunia, 2014;Raglin et al, 2022). Although there is limited available information regarding the interactions between flocs and these elements, it is noteworthy to mention that many of these elements can be influenced by the presence of chelating agents (Schwertmann et al, 1986;Fischer and Bipp, 2002).…”

Nitrification converts ammonium (NH4+) to nitrate (NO3−) using metalloenzymes, the activity of which depends on iron (Fe), molybdenum (Mo), and copper (Cu) availability. Iron-organic carbon coprecipitates (or Fe-OC flocs) are key byproducts of wastewater treatment industry and natural components of soil that may affect nitrification by changing the bioavailability of these metals. Here, we used flocs of different chemistry (aromatic and aliphatic) and known Fe and C composition to investigate their effects on nitrification in soils along a soil C gradient. Both aromatic and aliphatic flocs reduced net nitrification, but the magnitude of their effect was more pronounced in soils with low C content as opposed to those with high C content. Within each soil, both flocs reduced net nitrification similarly. In the presence of flocs, the bioavailability of Mo (assessed by changes in the concentration of water-soluble Mo) was dramatically decreased in low C soils, possibly because Mo was incorporated into or adsorbed to flocs or their decomposition products. In contrast, Mo bioavailability in high C soils was decreased to a lesser extent by flocs, likely because organic matter limited floc adsorption capacity and released Mo through mineralization. The depletion of bioavailable Mo by flocs in agricultural soils has the potential to impede soil nitrification and extend the residence time of NH4+ and its availability to plants and microbes.

“…However, Nitrospira accounts for only a very small proportion of the top 20 bacterial communities. A possible reason for these correlations is that, compared with other heterotrophic dominant groups, Nitrospira species are more sensitive to toxic substances such as heavy metals (Ferhan et al, 2010). Thus, Pb inhibits bacterial growth by damaging the cell membrane and interrupting the transport of nutrients.…”

IntroductionMangroves are a unique ecosystem, but are often affected by heavy metal pollution. Bacterial communities in mangrove sediments usually respond to heavy-metal pollution stress by expressing specific heavy-metal resistance genes (HMRGs).MethodsMultivariate statistics were performed on Metagenomics as well as environmental data to evaluated the effects of Cu addition on the sedimentary bacterial community structure.Results and discussionUsing metagenomics technology, we found that the Shannon andChao1 indices of natural sediments were significantly higher than in sediments with artificially added Cu. Addition of Cu significantly altered bacterial community structure and diversity at the phylum, class and order levels in sediments. The relative abundance of HMRGs in Cuadded sediments was lower than that in natural sediments. Environmental factors that affect bacterial communities also affect HMRGs. However, the contribution of heavy-metal pollution to the change in HMRG abundance was much lower than its contribution to the change in the bacterial community, indicating that the relationship between HMRG abundance and heavy-metal pollution is complex and needs to be comprehensively studied.
