“…illustrated the variation of the 16S rRNA copy numbers of anammox bacteria from both reactors. At the beginning of startup, the 16S rRNA anammox bacterial copy 13 numbers in seed sludge was measured as 9.91 × 10 7 copies/g biomass. With experiments going, the 16S rRNA anammox bacterial copy numbers in two reactors both exhibited an increase trend.…”

“…Also, previous investigations have shown that the RGO could be reduced from GO with anammox biomass [12]. Besides, Wang et al [13] reported that 75 mg/L RGO addition could increase total nitrogen (TN) removal rate of anammox biomass by 10.2%, although the promotion mechanism was not interpreted. Moreover, Yin et al [12] proved that 17.2% promotion of TN removal rate and 1.5-2 folds enhancement of enzymes activities of anammox biomass were tested with RGO addition.…”

Carbon nanomaterials like graphene, carbon nanotubes, fullerenes and the various forms of diamond have attracted great attention for their vast potential regarding applications in electrical engineering and as biomaterials. The study of the antibacterial properties of carbon nanomaterials provides fundamental information on the possible toxicity and environmental impact of these materials. Furthermore, as a result of the increasing prevalence of resistant bacteria strains, the development of novel antibacterial materials is of great importance. This article reviews current research efforts on characterizing the antibacterial activity of carbon nanomaterials from the perspective of colloid and interface science. Building on these fundamental findings, recent functionalization strategies for enhancing the antibacterial effect of carbon nanomaterials are described. The review concludes with a comprehensive outlook that summarizes the most important discoveries and trends regarding antibacterial carbon nanomaterials.

“…While the antimicrobial effects of GO have been demonstrated in culture studies, only a few studies determined the effects of GO on microbial communities inhabiting environmental samples (Ahmed and Rodrigues, 2013;Wang et al, 2013). GO exhibited a toxic effect on the wastewater microbial communities at concentrations from 0.05 to 0.3 mg ml − 1 , and reduced their metabolic activity by 20-70% in a concentration-dependent manner.…”
