  • We participated with three abstracts at the ERES 2020 Virtual Conference

    Between 3-6 October, 2020 we participated at the ERES 2020 Virtual Conference, (http://eres2020.eres-conference.eu/ ) organised by the SCALE and the secREEts projects and sponsored by Mytileneos and MEAB.

    This was the 3rd Conference on European Rare Earth Resources originally planned to be held in Delphi, Greece.

    However, due to the ongoing COVID19 crisis, the organizing committee of the ERES 2020 conference has decided to move the conference to a virtual venue.

    Our group participated with three abstracts, presented in one lecture by Viktoria Feigl.

    The below listed abstracts can be viewed also in the list of abstracts: http://eres2020.eres-conference.eu/index.php/abstracts/

    We participated at the 6th European Conference on Cyclodextrins (EURO CD 2019) (https://eurocd2019.com/) organised in Santiago de Compostela, Spain, between 2-4 October, 2019.

    The goal of EURO CD 2019 was to offer a multidisciplinary meeting point for scientists involved in cyclodextrin production, chemistry and modelling, or applications in diverse fields including analytical chemistry, drug formulation, gene therapy, regenerative medicine, cosmetics, food, bioremediation and agriculture.

    The attendees had an excellent opportunity to learn the latest findings on raw materials, products, procedures and equipment affecting cyclodextrin field, and how to integrate them into the own research, to directly engage people working in complementary fields, make professional connections and create scientific synergies, to discover the similar challenges faced by other researchers and keep the mind open to novel ways of dealing with chemistry, biomedical, food technology and ecological problems exploiting the endless capabilities of cyclodextrins.

    Our group was represented at EURO CD 2019 by 3 members: Mónika Molnár, Ildikó Fekete Kertész and Zsófia Berkl, presenting 3 posters.

    Mónika Molnár presented a poster on cyclodextrin mediated quorum quenching in the Aliivibrio fischeri bioluminescence model system.

    The conferences covered a wide range of research themes under the umbrella of Chemical Engineering and Applied Biotechnology. The topics treated were all typical of Chemical Engineering and Applied Biotechnologies, from the classical ones, like process simulation and reactor design, to the most current ones, like nanotechnologies, bio-fuels, bio-catalysts, food and water, that represent the challenges of the future and are of interest to everybody.

    Our group was represented by Emese Vaszita, who presented in an e-poster the most recent results of one of our research topics, biochar, as soil amendment. The poster detailed the results of a laboratory incubation study monitoring the effects of artificial biological aging on the physicochemical, biological and ecotoxicological properties of five biochar types.

    The e-poster can be viewed at the conference webpage (Screen 44, P/392): http://www.livecongress.it/posters/public/viewer/C456CB6E#posters/screen-04

     Summary:

    The ELECTRA project is a EU-China RTD joint initiative that will deliver 2 innovative sets of novel electromicrobiology based environmental biotechnologies, facilitating/improving electron transfer during microbial degradation processes. Our approach will accelerate the elimination of several classes of pollutants and mixtures thereof in contaminated wastewater, groundwater, sediment and soil.

    The first set of biotechnologies employs bioelectrochemical systems requiring low energyinput and no chemical addition.

    The second set comprises biotechnologies, which necessitate no energy input and minimal chemical amendment using electromicrobial concepts.

    ELECTRA biotechnologies will build on recent groundbreaking advances in biotechnology to develop them for environmental bioremediation applications and test the 4 most advanced technologies during field trials under various environmentally relevant conditions in both Europe (4 sites with contaminated wastewater, groundwater, soil, and sediment) and China (4 sites: mirroring tests concept) to prove their efficiency and robustness.

    The ELECTRA project deliberately addresses the accelerated elimination of compounds representative of hydrocarbons and derivatives, emerging pollutants, metals and nutrients and mixtures thereof in environmentally relevant concentration as a wise and careful approach taking into account the real problem of contaminations by organic and inorganic pollutants as well as nutrients.

    The ELECTRA project addresses the accelerated elimination of:

    1. Hydrocarbons (TPHs: polycyclic aromatic hydrocarbons and alkanes) and their halogenated derivatives (e.g.chlorinated aliphatic hydrocarbons (CAHs), polychlorobiphenyls (PCBs, halogenated aromatics);
    2. Metals (Sb, Pb, As, Hg, Cd, Zn);
    3. Nutrients (NH4+ and NO3-)
    4. Emerging micropollutants: antibiotics (e.g. fluoroquinolones and sulphonamides); flame retardants and endocrine disrupting chemicals (e.g. tetrabromobisphenol A and bisphenol A) and pesticides (e.g. bromoxynil and propiconazole).

    The environmental impacts and financial costs associated with ELECTRA’s bioremediation technologies will be estimated from a life cycle and risk perspective to support the decision process in future treatment selections.

    LCA will be used to evaluate the efficiency of the remediation technologies and to choose the technology Champions to be tested.

    A web-based EDSS (Environmental Decision Support System) will be developed to help support relevant decision makers in selecting the most appropriate treatment option for target applications based on technical, environmental and economic criteria.

    The main task of the Environmental Microbiology and Biotechnology Research group within BME’s Applied Biotechnology and Food Science Department will be ecotoxicological monitoring of the experiments.

    A problem-specific and complex monitoring methodology will be developed and applied by BME to follow changes in the ecotoxicity of contaminated WW, GW, soil and sediment before and after technology applications. The toxicity associated to the contaminated matrixes of the selected sites will be evaluated using a suite of ecotoxicity tests. For each matrix/contaminant, the most suitable ones will be then selected for the evaluation of the toxicity changes at the end of the bioremediation processes. For each matrix, test organisms from at least three trophic levels will be chosen and extrapolation to the complex ecosystem will be carried out.

    Acute, chronic toxicity and genotoxic effects will be tested with standardized (based on ISO and OECD standards) or pollutant-specific test methods (e.g. D. magna heartbeat rate test for micropollutants). For the pollutant and matrix specific (WW, GW, soil, sediment) ecotoxicity toolkit BME will select the best combination of the following test organisms: Aliivibrio fischeri (luminescent aquatic bacterium), Bacillus subtilis (soil bacterium), Salmonella typhimurium (in Ames-test), Lemna minor (aquatic plant), Sinapis alba and Triticum aestivum (terrestrial plants), Tetrahymena pyriformis (protozoan), Daphnia magna (water living crustacean), Heterocypris incongruens (sediment living ostracoda), Folsomia candida (soil living insect), Enchytraeus albidus (potworm), etc. Except for aquatic test organisms, most of them can be applied for the testing of both liquid and solid samples.

    In case of soils and sediments, both water extracts and whole soil/sediment samples (direct toxicity assessment, DTA) will be tested. DTA draws the attention to the chemically unmeasured or non-measurable, but existing hazardous components.

    BME will be involved also in Life Cycle Assessments (LCA) of the different technologies to estimate environmental impacts associated with the application of the technology and in the development of the knowledge base of the multi criteria EDSS.
