|“Implications and Applications of the toxicity of nanoparticles”|
|As nanotechnology flames the enthusiasm of scientific and technical communities, research aimed at preventing adverse consequences is also occurring at an unusually early stage in the development cycle of a new technology. Our team positions itself in line with this trend: in parallel, we are working on the mechanisms of antibacterial properties of nanoparticles and on the development of engineered disinfection systems. In our proactive approach to nanotoxicity management, our objective is to place a positive spin on the bactericidal properties by, for example, using nanoparticles as a new key substance in the processes of drinking water treatment. More specifically, we focus on fullerene (C60 and nC60), fullerol and carbon nanotubes suspended in solvents (water or organic solvent). We examine their photosensitivity while exposed to UV light. We are also currently loading these nanoparticles in polymeric membranes to ascertain their effect on the mechanical and separation properties of the membranes, while expecting a significant reduction of biofouling.|
|The widespread production of engineered nanomaterials and their rapid incorporation into a variety of consumer products and applications is outpacing the research into their health and environmental impacts. Currently, the degree to which cellular processes and ecosystem health may be impacted by nanomaterials, let alone specific toxicity mechanisms, remain largely unknown. The effect of these nanomaterials on microbes is an important consideration due to the role of microbes as the basis of food webs and the primary agents for global biogeochemical cycles. Microorganisms are also important components of soil health and could serve as potential mediators of transformations that affect nanoparticle mobility and toxicity in the environment. In an attempt to contribute to proactive risk management, our research examines the potential impacts of nanomaterial use and disposal on microbes, with the primary focus on fullerenes. We have examined the antibacterial activity of SiO2, TiO2, ZnO, and a fullerene-water suspension named nC60. We are currently determining the mechanism behind the antibacterial activity of nC60 to prevent unintentional ecosystem damage and/or exploit its antibacterial properties in engineered disinfection systems. We are also monitoring the impact of nC60 and powdered C60 on soil microcosms to ascertain the effect of fullerenes on soil microbial communities.|
|“Bio-response to Adsorption of Nanomaterials with Different Adsorbents”|
|In recent decades, nanotechnology has been booming in both scientific and marketing areas. Nanosized materials are often hailed for their extraordinary properties. But these also raise concerns of unique toxicity. What is the transfer and fate of these nanomaterials, what kind of bio-impact will they bring are still waiting for exploration. Microbes, as the foundation of the whole biosphere, deserve the primary concern to study their response when exposed to nanomaterials. On the basis of former study, which has shown toxicity of nC60 (fullerene-water suspension) to bacteria, we are examining bacterial response to nC60 when n60 is adsorbed to different adsorbents. Granular activated carbon, silica gel and polystyrene beads are chosen to test the relationship between toxicity of nC60 and bioavailability.|
|“Reductions in DNAPL Longevity Through Biological Flux Enhancement”|
|Reductions in DNAPL Longevity Through Biological Flux Enhancement Remediation of aquifers contaminated with chlorinated solvents (CAH) such as tetrachloroethene (PCE) and trichloroethene (TCE) is a multi-billion dollar problem for industry and federal government. Estimates of the number of sites containing CAH contamination has been placed near 3000. The most frequently used treatment technologies (pump-and-treat, zero-valent iron barriers) focus on management of CAH plumes rather than dense non-aqueous phase liquid (DNAPL) source zones that slowly dissolve over years to produce plumes. Therefore, present technology treats the symptoms rather than the cause. Source zone bioremediation harnesses the natural metabolism of dehalorespiring organisms, capable of thriving at high concentrations of chlorinated solvent contamination, to modify the dissolution characteristics of DNAPLs. If source zones could be effectively treated using low cost bioremediation technology, significant reduction in remediation life cycle costs could be achieved. The objective of this project was to conduct a quantitative demonstration of DNAPL source zone bioremediation in a cost-effective manner with a known initial DNAPL mass and composition and a parallel independent control. More specifically: 1) provide a basis for critical analysis of the extant field data from ongoing tests to determine if source zone longevity is being biologically impacted at these sites; 2) allow for the characterization of the microbial ecology in a NAPL source zone using molecular techniques for tracking and enumerating critical populations; 3) allow for the assessment of differences in source zone architecture on bioremediation potential; and, 4) develop a basis for cost and effectiveness considerations at field scales. We have demonstrated that rapid dechlorination activity can occur in the immediate vicinity of pure DNAPL causing dramatic changes in the mass transfer and partitioning characteristics of the DNAPL, and result in rapid DNAPL dissolution.|
|“The Impact of Metals on LuxI/LuxR Quorum Sensing and Biofilm Inhibition “|
|The Impact of Metals on LuxI/LuxR Quorum Sensing and Biofilm Inhibition Biofilms are a community of microorganisms held together by an extracelluar glue known as a glycocalyx. Biofilms are ubiquitous in nature; they are found on the surface of rocks in river streams, as plaque on the surface of teeth, and are utilized in wastewater treatment processes to break down organics and to remove nutrients (Ghannoum and O’Toole 2004). Although biofilms provide a key role in bioremediation, they can cause significant environmental damage via microbial induced corrosion (MIC). Microbial induced corrosion is the corrosion of materials by microorganisms either directly or indirectly, through the production of organic acids, depassivation of surfaces, or the direct attack of a component, all of which wear away the surface of the material (Hernandez-Gayosso 2004). Billions of dollars per year are spent replacing failing infrastructure such as water lines and cooling equipment due to MIC. Because of their use in bioremediation and their potential for environmental damage, the ability to control whether a biofilm forms to its subsequent activity would be of significant interest to environmental engineers and scientists. We propose to investigate the influence of metals, particularly, nickel, on LuxI/LuxR quorum sensing and biofilm formation. Although the impacts of metals on cellular metabolism have been studied, there has been little research performed on how nickel and other metals can impact biofilm formation via quorum sensing. Research in this area comes at an opportune time; there is a need to prevent biofilm formation on, among other things, infrastructure and medical implantations. There is sufficient research that shows that biofilm formation can be influenced and/or controlled by quorum sensing. Finally, there is interest in multiple academic communities on developing protocols to mediate quorum sensing which allows study of this phenomena from an interdisciplinary perspective. This project offers an opportunity to create a collaborative forum between government agencies and academia to solve a problem that has widespread implications.|
|“Microbial degradation of 7-ketocholesterol”|
|7-ketocholesterol, like many oxysterols, belongs to a regulatory class of molecules with diverse activity. Some examples are promotion of cellular apoptosis, regulation of reverse cholesterol transport and sphingolipid metabolism, platelet aggregation, protein prenylation and activation of pro-inflammatory cytokines. Some oxysterols can also compromise ecological health by acting as endocrine disruptors. I am investigating the mechanism of microbial 7-ketocholesterol degradation in order to isolate and characterize the enzymes involved.|
|“Groundwater Transport, reservoir amplification, and natural attenuation of antibiotic resistance vectors”|
|Genes as Environmental Pollutants: Currently little is known about the behavior and properties of antibiotic resistance genes in typical environmental settings with respect to their transport and the development, amplification and possible attenuation of microbial antibiotic resistance. The motivation for my work arises from the need for better basic understanding of the environmental properties of this emerging pollutant. My work seeks to advance the understanding of the development, amplification and potential attenuation of antibiotic resistance in indigenous soil microorganisms exposed to antibiotics, and/or antibiotic resistance gene vectors that are released to the environment as a result of animal agricultural practices under varying antibiotic dosing scenarios. Emphasis is placed on studying the soil/water interface because direct runoff and groundwater infiltration represent likely human exposure pathways to antibiotic resistant bacteria. The goals of this research are to characterize: (1) the effect of antibiotic exposure on the dynamics of microbial antibiotic resistance, (2) effect of antibiotic exposure on inter-specific tet-gene transfer, (3) effect of antibiotic exposure on resistance plasmid dynamics in pure tetR cultures, and (4) resistance vector transport in porous media.|
