TLDR
The results showed that GO had a limited effect on ARB inactivation, and all tested concentrations of GO promoted the conjugative transfer from 1to over 3 folds, with low concentrations and high concentration of GO samples the least promoted.About:

Effects of graphene oxide on the performance, microbial community dynamics and antibiotic resistance genes reduction during anaerobic digestion of swine manure.
TL;DR: Network and SEM analysis indicated that changes of each ARG was closely associated with variation of microbial community composition, environmental variables contributed most to the dynamics of ARGs indirectly, GO influenced the ARGs dynamics negatively and (heavy metal resistance genes (MRGs) influenced the most directly.
Journal ArticleDOI
Nano)microplastics promote the propagation of antibiotic resistance genes in landfill leachate
TL;DR: The presence of N/MPs in leachate promoted the propagation of ARGs due to their impacts on the bacterial community and cellular membrane permeability, which has important implications for understanding the environmental risks of the combined pollution of N /MPs and ARGs.

Antibacterial Activity of Graphite, Graphite Oxide, Graphene Oxide, and Reduced Graphene Oxide: Membrane and Oxidative Stress
Shaobin Liu,Tingying Helen Zeng,Mario Hofmann,Ehdi Burcombe,Jun Wei,Rongrong Jiang,Jing Kong,Yuan Chen +7 more
TL;DR: In this paper, the antibacterial activity of four types of graphene-based materials (graphite (Gt), graphite oxide (GtoO), reduced graphene oxide (rGO), and reduced GtO) toward a bacterial model (Escherichia coli) was investigated.

Toxicity of Graphene and Graphene Oxide Nanowalls Against Bacteria
Omid Akhavan,Elham Ghaderi +1 more
TL;DR: It was found that the cell membrane damage of the bacteria caused by direct contact of theacteria with the extremely sharp edges of the nanowalls was the effective mechanism in the bacterial inactivation.
Journal ArticleDOI
Graphene-Based Antibacterial Paper
TL;DR: Graphene-based nanomaterials can effectively inhibit the growth of E. coli bacteria while showing minimal cytotoxicity and it is demonstrated that macroscopic freestanding GO and rGO paper can be conveniently fabricated from their suspension via simple vacuum filtration.

Antibiotic Resistance Genes as Emerging Contaminants: Studies in Northern Colorado†
TL;DR: It was noted that tet(W) and tet(O) were also present in treated drinking water and recycled wastewater, suggesting that these are potential pathways for the spread of ARGs to and from humans.

Correlation of tetracycline and sulfonamide antibiotics with corresponding resistance genes and resistant bacteria in a conventional municipal wastewater treatment plant
TL;DR: The gene abundances of tetO and tetW normalized to that of 16S rRNA genes indicated an apparent decrease as compared to sulI genes, which remained stable along each treatment stage, while a significant correlation was observed for sulI gene and total concentration of sulfonamides.
