Journal ArticleDOI
Silver nanoparticles: Toxicity in model organisms as an overview of its hazard for human health and the environment
Gonzalo Tortella,Olga Rubilar,Nelson Durán,María Cristina Diez,Miguel Martínez,J. Parada,Amedea B. Seabra +6 more
TL;DR: The current state of the art and perspectives for the impact of AgNPs on different organisms present in the environment are reported and recent progress in interpreting uptake, translocation and accumulation mechanisms in different organisms and/or living animals are discussed, as well as the toxicity ofAgNPs and possible tolerance mechanisms in live organisms to cope with their deleterious effects.
Journal ArticleDOI
Revealing the role of adsorption in ciprofloxacin and sulfadiazine elimination routes in microalgae.
TL;DR: Findings reveal the possible biological mechanisms of biosorption and biodegradation of PPCPs in microalgae, which could further enhance the feasibility of microalgal applications for simultaneous P PCPs remediation and alternative energy production.
Journal ArticleDOI
Acute effects of nanoplastics and microplastics on periphytic biofilms depending on particle size, concentration and surface modification.
Lingzhan Miao,Jun Hou,Guoxiang You,Zhilin Liu,Songqi Liu,Tengfei Li,Yujuan Mo,Song Guo,Hao Qu +8 more
TL;DR: N nanoplastics have potential to disrupt the basic ecological functions of biofilms in aquatic environments and the antioxidant activity of biofilm was enhanced as indicated by the increased total antioxidant capacity (T-AOC).
Journal ArticleDOI
Impact of adding metal nanoparticles on anaerobic digestion performance - A review.
TL;DR: The traditional view on the cytotoxicity of NPs to living organisms and the contemporary view of mechanisms for enhancement in anaerobic digestion performance in the presence of metal NPs are reviewed.
Journal ArticleDOI
Iron-assisted biological wastewater treatment: Synergistic effect between iron and microbes
Tian Tian,Han-Qing Yu +1 more
TL;DR: An overview of iron-assisted biological wastewater treatments, including anaerobic digestion, S and Cl reduction, N and P removal, heavy metal immobilization, aromatic and halogenated hydrocarbon compounds degradation, and sludge granulation is provided, and the potential synergistic effects between iron and microbes involved in these processes are explored.

Mechanisms of biofilm resistance to antimicrobial agents
Thien-Fah Mah,George A. O'Toole +1 more
TL;DR: Owing to the heterogeneous nature of the biofilm, it is likely that there are multiple resistance mechanisms at work within a single community.
Journal ArticleDOI
Extracellular polymeric substances (EPS) of microbial aggregates in biological wastewater treatment systems: a review.
TL;DR: As EPS are very complex, the knowledge regarding EPS is far from complete and much work is still required to fully understand their precise roles in the biological treatment process.
Journal ArticleDOI
Resistance, resilience, and redundancy in microbial communities
TL;DR: It is found that the composition of most microbial groups is sensitive and not immediately resilient to disturbance, regardless of taxonomic breadth of the group or the type of disturbance, and a simple framework to incorporate microbial community composition into ecosystem process models is proposed.
Journal ArticleDOI
Quorum sensing signal–response systems in Gram-negative bacteria
Kai Papenfort,Bonnie L. Bassler +1 more
TL;DR: This Review examines how features of quorum sensing signal–response systems combine to control collective behaviours in Gram-negative bacteria and the implications for host–microbial associations and antibacterial therapy.
Journal ArticleDOI
Metal nanoparticles: understanding the mechanisms behind antibacterial activity.
TL;DR: Proposed mechanisms of antibacterial action of different metal NPs include the production of reactive oxygen species, cation release, biomolecule damages, ATP depletion, and membrane interaction.
