“…Proteobacteria, one of the dominant bacterial phyla, showed a decreasing trend in most treatment (Table S6). Likewise, previous studies have reported that abundance of Proteobacteria decreased under stress from the M-NPs (e.g., ZnO and Fe 0 NP) in OCO reactor and landfill leachate (Liu et al, 2018;Shi et al, 2019). The trend of Actinobacteria changes was similar to ARGs changes, such as sul1, aac(6')-Ib, and ermB, which implies that Actinobacteria may have been responsible for the increasing trend of ARG in the samples.…”

Most studies of whether and how nanoparticles (NPs) affect antibiotic resistance genes (ARGs) focus on testing single NPs type. In this study, we determined the combined effect of Cu- and ZnO- NPs in the water samples collected from the Yangtze River Estuary and found the effect differs greatly from that produced by individual NPs. The results showed that the Cu- and ZnO- NPs co-exposure resulted in an enrichment of ARGs, whereas individual Cu- and ZnO- NPs exposure decreased the abundance of ARGs. Furthermore, the co-exposure of Cu- and ZnO- NPs induced obvious changes in the microbial communities compared to the control communities. Redundancy analysis suggested that the microbial community contributed the most (43.5%) to the ARG profiles, followed by dissolved metal ions (25.7%), MRGs, (19.4%), and MGEs (4.4%). Network analysis found several potential hosts (such as Mycobacterium and Escherichia coli) and implied the extent of the risk of ARG transmission into various environmental niches by these common microbes.

Evaluation of performance and microbial community successional patterns in an integrated OCO reactor under ZnO nanoparticle stress

Abstract: An integrated OCO reactor was used to investigate the performance and microbial community successional changes under a long-term exposure to relatively low-level ZnO nanoparticles (NPs).
