Micro(nano)plastic size and concentration co-differentiate nitrogen transformation, microbiota dynamics, and assembly patterns in constructed wetlands

Early stage of biofilm assembly on microplastics is structured by substrate size and bacterial motility

“…Various parameters are known to determine the taxonomic structures of MP‐associated biofilms [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. For example, one study pointed out that the microbial diversity and uniformity in MP‐associated biofilms are higher than those in seawater, and they are co‐influenced by polymer types and exposure duration [ 11 ].…”

“…Interestingly, the color of the plastic was also found to affect both the taxonomic structure and functional composition of MP‐associated biofilms [ 13 ]. Moreover, the relationship between MP size (diameter) and the functional properties of MP‐associated biofilms has been investigated in a few studies [ 14 , 15 , 16 ]. For example, in wastewater treatment systems, the MP size influences the environmental behavior of antibiotic‐resistance genes [ 14 ].…”

The contribution shift of ammonia-oxidizing archaea and bacteria to ammoxidation under Ag-NPs/SWCNTs/PS-NPs stressors in constructed wetlands

“…Furthermore, the ENMs could be as a selection pressure, which promoted an adaptive reconstruction of co-occurrence relationship between AOA and AOB. In the novel pattern, the more intensive co-occurrence pattern provided a more suitable and effective interaction relationships for metabolism, signal exchange and electronic transport among AOMs [59]. Overall, the gathering of ENMs in CWs possibly enhanced interspecific interactions and created a novel niche for AOMs in CWs.…”

“…Co-occurrence network analysis and the phylogenetic investigation of communities via reconstruction of the unobserved states was conducted to analyse the coexistence patterns [Spearman's ρ > 0.8 (positive) or < -0.8 (negative) and P < 0.01] and the functional pathway profiles (PICRUSt2) of AOA and AOB based on the high-throughput sequence of the 13 C-labeling DNA samples. The details of script and database are described within our previous study [59], respectively.…”

Salinity causes differences in stratigraphic methane sources and sinks

“…Co-occurrence networks have been extensively applied to study the potential microbial interactions that affect community composition and ecosystem function, providing supporting information on microbial ecology [ 30 , 31 ]. A dense microbial co-occurrence network offers an easy and efficient series of interactions for metabolism, signal exchange, and electron transfer between microorganisms [ 32 ]. Based on the co-occurrence network analysis of methanogens from 39 paddy soils, researchers found that commonly co-occurring methanogenic groups interacted more closely and contributed more to methane emissions [ 33 ].…”
