We participated at EURO CD 2019, in Santiago de Compostela, Spain, 2-4 October, 2019
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 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:
- Hydrocarbons (TPHs: polycyclic aromatic hydrocarbons and alkanes) and their halogenated derivatives (e.g.chlorinated aliphatic hydrocarbons (CAHs), polychlorobiphenyls (PCBs, halogenated aromatics);
- Metals (Sb, Pb, As, Hg, Cd, Zn);
- Nutrients (NH4+ and NO3-)
- 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.

Summary
The Difpolmine project aimed to reduce pollutant flows through both water and air in the area of the former Salsigne and Combe du Saut mines. It planned to develop a new cleaning system that would use, but also go beyond traditional cleaning treatments of excavation, confinement and solidification. In particular, it sought to optimise water management systems in the area and investigate the feasibility of an adapted soil phytostabilisation methodology to minimise residual and diffuse pollution and its subsequent impact. Phytostabilisation consists in using plants which are able to contain, degrade or eliminate pollutants such as metals and pesticides from the medium in which they are contained. Whilst the project looked to demonstrate the applicability of this technique to the specific conditions of the project area in France, it also aimed to prove its transferability to a different mining site in Hungary: a closing zinc and lead mine at Gyöngyösoroszi. It thus hoped to provide an example and source of information for managers of metal-polluted sites in a range of countries and sites. The project contributed to the development of a full treatment plan for the Gyöngyösoroszi mine site in Hungary, based on a study of the adaptation of the project methodology to its particular characteristics. This shows the potential for use of adapted versions of this methodology across various sites around Europe.
Project Work at the Hungarian demonstration site
The postmining activities at the Hungarian site required the management of both the point and diffuse sources. The main environmental risks were related to the mobile Cd and Zn content of the mine wastes, surrounding soils and transported sediments, endangering the surface waters. The toxic metals originated from the exploited sulphide ore veins hosted in andesite rocks. 1–3 pH leachate was produced around the waste rock heaps due to the complex chemical and biological oxidation of the pyrite containing material in contact with the rainwater and runoff. A complete Environmental Risk Management methodology was worked out. The approach was „GIS based” and „catchment scale”, using a three tiered, iterative Environmental Risk Assessment methodology and development of a combined chemical and phytoremediation technology, able to reduce mobility, biological availability of toxic metals, providing long term reduction of toxic metal emission and transport via any pathway. http://www.eugris.info/DisplayProject.asp?p=4512

Project title: „LOKKOCK” Development of novel soil testing methods in support of site-specific risk assessment
Funding Programme: Economic Competitiveness Operative Programme (GVOP)
Project Identification Number: GVOP-3.11-2004-05-0257/3.0
Project duration: 01. 01. 2005. – 31. 12. 2007.
Project type: Consortial

Research Institute for Soil Science and Agricultural Chemistry of the Hungarian Academy of Sciences (RISSAC)
Cyclolab Cyclodextrin Research and Development Ltd (CYCLOLAB)
Summary „LOKKOCK” Development of novel soil testing methods in support of site-specific risk assessment
The Project was focused on the development of innovative soil testing methods that support site-specific risk assessment of polluted sites.
The main aim of the work was to develop and apply physico-chemical analyses, biological and ecotoxicity testing methods to soil, DNA soil testing procedures and to forecast the ecological effects of the contaminant in the soil and to determine the site-specific quantitative risk.
The integrated use of the developed methods assisted in mapping of polluted areas, forecasting and measuring the ecological effect and site-specific risk of the contaminants, providing data on the pollution, bioavailability, contaminant mobility, bioaccumulation and food chain effects.
Therefore, the developed integrated methodology and the related risk assessment procedure was able to support environmental decision making in environmental risk management.
Three complementary test methods were developed and implemented:
- Physical-chemical methods for quantitative and qualitative determination and characterisation of toxic metals and organic contaminants, determination of partition and contaminant transport.
- Biological and DNA techniques for Qualitative and Quantitative characterisation of the members of the ecosystem.
- Direct soil contact and DNA toxicological tests to measure the effect of the contaminated environmental samples.
