Although the fate of nanoplastics (<100 nm) in freshwater systems is increasingly well studied, much less known about its potential threats to cyanobacterial blooms, ultimate phenomenon eutrophication occurrence worldwide. Previous studies have evaluated consequences increasing membrane permeability microbes, however, there no direct evidence for interactions between and microcystin; intracellular hepatotoxins are produced by some genera cyanobacteria. Here, we show that amino-modified...
Diets comprising selenium-deficient crops have been linked to immune disorders and cardiomyopathy. Selenium nanoparticles (SeNPs) emerged as a promising nanoplatform for selenium-biofortified agriculture. However, SeNPs fail reach field-scale applications due poor understanding of the fundamental principles its behavior. Here, we describe transport, transformation, bioavailability through combination in vivo vitro experiments. We show synthesized amorphous SeNPs, when sprayed onto leaves...
Understanding the fundamental interaction of nanoparticles at plant interfaces is critical for reaching field-scale applications nanotechnology-enabled agriculture, as processes between and root such compartments exudates remain largely unclear. Here, using iron deficiency–induced chlorosis an indicator phenotype, we evaluated transport capacity Fe 3 O 4 coated with citrate (CA) or polyacrylic acid (PAA) in rhizosphere. Both can be used a regulator hormones to promote elongation, but they...
Integration of methanogenic archaea with photocatalysts presents a sustainable solution for solar-driven methanogenesis. However, maximizing CH 4 conversion efficiency remains challenging due to the intrinsic energy conservation and strictly restricted substrates archaea. Here, we report biotic–abiotic hybrid (biohybrid) system by incorporating cadmium sulfide (CdS) nanoparticles rationally designed archaeon Methanosarcina acetivorans C2A, in which glucose synergist protein kinase, an...
Biohybrid systems that integrate microorganisms with nanomaterials have emerged as promising solutions for sustainable nitrogen fixation. However, key challenges, such the dependence on light and vulnerability of nitrogenase to oxidative damage, limited their application. Here, we report a novel, light-independent biohybrid system integrating Fe3O4 nanoparticles Methanosarcina acetivorans C2A, resulting in significant enhancement both fixation activity methane production. facilitate...
Microbial communities and methanogenic genes are main reasons for AGS performance recovery from PS-NPs exposure.
The toxicity of nanoparticles to freshwater microalgae is significant importance in maintaining the overall stability aquatic ecosystems. However, transport mechanism and response towards nanoplastics (NPs) remain be further investigated. In this study, we examined internalization mechanisms polystyrene (PS-NPs) microalga Chlorella sorokiniana. results revealed that PS-NPs inhibited algal cells' growth disrupted cell integrity upon contact, leading shrinkage or rupture. Moreover,...
The transport behavior of microplastics in soil environments is significantly affected by dissolved organic matter (DOM). However, the regulation different types DOM on media poorly understood, especially at a quantitative level. In this study, we found that three DOM, humic acid (HA), bovine serum albumin (BSA), and sodium alginate (SA), promoted polystyrene (PS) column experiments. PS was stronger with increasing concentrations. Among HA mobility most due to electrostatic repulsion steric...
As essential primary producers, cyanobacteria play a major role in global carbon and nitrogen cycles. Though the influence of nanoplastics on metabolism is well-studied, little known about how affect their metabolism, especially under environmentally relevant concentrations. Here, we show that forms regulated growth inhibition, consumption, synthesis release microcystin (MC) Microcystis aeruginosa exposed to 10 μg/mL amino-modified polystyrene (PS-NH2) with particle size 50 nm concentrations...
Antibiotic resistance is a global health challenge, and the COVID-19 pandemic has amplified urgency to understand its airborne transmission. The bursting of bubbles fundamental phenomenon in natural industrial processes, with potential encapsulate or adsorb antibiotic-resistant bacteria (ARB). However, there no evidence date for bubble-mediated antibiotic dissemination. Here, we show that can eject abundant air, form stable biofilms over air-water interface, provide opportunities cell-cell...
Methanogenic archaea, characterized by their cell membrane lipid molecules consisting of isoprenoid chains linked to glycerol-1-phosphate via ether bonds, exhibit exceptional adaptability extreme environments. However, this distinct architecture also complicates the interactions between methanogenic archaea and nanoparticles. This study addresses challenge exploring interaction transformation selenium nanoparticles (SeNPs) within archaeal Methanosarcina acetivorans C2A. We demonstrated that...
Seed priming with nanomaterials is an emerging approach for improving plant stress tolerance. Here, we demonstrated a mechanism enhancing salt tolerance in rice under via nonstimulatory nanoparticles such as selenium (SeNPs), distinct from stimulatory nanomaterials. Due to the dynamic transformation ability of SeNPs, SeNP could enhance by mediating glutathione cycle eliminate excess reactive oxygen species (ROS). During priming, SeNPs penetrated seeds and transitioned into soluble form...
