报告摘要：

Saline lakes are defined as havingsalinity of at least 1 g/L. Inland saline lakes occur on every continent, andtheir total number and volume on Earth is comparable to that of all freshwaterlakes. They are very diverse regarding their origin and physicochemicalfeatures, which determine their inhabiting microbial communities. In thepresentation I will share the results of our research group conducted on sodalakes, which are special types of saline aquatic habitats having permanentlyalkaline pH. The Westernmost occurrence of these sites in Eurasia is withinEurope (Hungary, Austria and Serbia). On the other hand, several other salinelakes could be found in Europe, which we have studied recently. Some of themare deep and have heliothermal character, which means that intensive solarwater heating process below the slightly saline surface layer causes subsurfacethermal maxima. A huge diversity of aerobic and anaerobic microbes thrive inthese sites which were studied by the combination of classic microbiologicaltechniques (cultivation and microscopic methods) with modern genomic tools(amplicon sequencing, metagenomics and prokaryotic genomics).

报告摘要：

Aliphatic and aromatic short-chainhydrocarbons and its halogenated derivatives cause serious environmentaldamages all over the world. In situ bioremediation techniques are feasible andinnovative methods to eliminate short-chain halogenated hydrocarboncontaminations by stimulating microbes (biostimulation) involved indecomposition processes or using dechlorinating microbial inocula(bioaugmentation). The ability to degrade aliphatic, aromatic and polyaromatichydrocarbons are widespread among the microorganisms, while chlorinatedaliphatic hydrocarbons can be reduced by a member of genus Dehalococcoides asthe only group of microorganisms capable of the complete dechlorination ofchlorinated ethenes to non-toxic ethene under anaerobic conditions. The aim ofpresent study was to isolate and enrich microorganisms and microbialcommunities capable of chlorinated hydrocarbon degradation. We intended todevelop bioaugmentation agents for the bioremediation of contaminated sites, toreveal their microbial community composition, to identify the microorganismsinvolved in the process and to monitor their effects under field conditions.
