Polyphasic bacterial community analysis of an aerobic activated sludge removing phenols and thiocyanate from coke plant effluent.
The microbial community of a lab-scale activated sludge system treating coking effluent was assessed by cultivation-based and culture-independent techniques and applied polyphasic approach showed a simple microbial community dominated by easily culturable heterotrophic bacteria. Expand
Screening and evaluation of some green algal strains (Chlorophyceae) isolated from freshwater and soda lakes for biofuel production.
A new strain of Chlorophyceae species isolated from freshwater and soda lakes in Hungary and Romania (Central Europe) has potential as a feedstock for the production of excellent quality biodiesel. Expand
Development of a 16S rRNA gene-based prototype microarray for the detection of selected actinomycetes genera
A 16S rRNA-based taxonomic microarray that targets key actinomycetes at the genus level is developed and proposed that this newly constructed microarray will be a valuable tool for genus-level comparisons of act inomycete communities in various ecological conditions. Expand
Assessment of the natural attenuation of chlorinated ethenes in an anaerobic contaminated aquifer in the Bitterfeld/Wolfen area using stable isotope techniques, microcosm studies and molecular
The integrated approach, using metabolite spectra, molecular marker analysis and isotope studies, provided several lines of evidence for natural attenuation of the chlorinated ethenes. Expand
Characterization of photoautotrophic picoplankton assemblages in turbid, alkaline lakes of the Carpathian Basin (Central Europe)
The photoautotrophic picoplankton of ten shallow, hyposaline soda lakes located in three different geographical regions in the Carpathian Basin was characterized and confirmed that PPP might exploit different aquatic ecosystems and be successful even in the case of abrupt changes of environmental parameters.

Vertical physico-chemical gradients with distinct microbial communities in the hypersaline and heliothermal Lake Ursu (Sovata, Romania)
Characteristic microbial communities with various prokaryotic taxa were identified along the different environmental parameters present in the different water layers of Lake Ursu. Expand
Detection of potentially pathogenic bacteria in the drinking water distribution system of a hospital in Hungary.
The results obtained verify the higher sensitivity of PCR compared to cultivation for detecting Legionella and Pseudomonas aeruginosa, emphasizing that drinking water systems, especially those with stagnant water sections, could be the source of nosocomial infections. Expand
Winter bloom of picoeukaryotes in Hungarian shallow turbid soda pans and the role of light and temperature
The seasonal dynamics of picophytoplankton communities in shallow turbid alkaline pans in Hungary was studied between July 2006 and May 2007. Similarly to other aquatic environments in the temperateExpand
First record of picophytoplankton diversity in Central European hypersaline lakes
The aim of this study was to identify PPP members both in the summer and the winter communities using molecular biological techniques, denaturing gradient gel electrophoresis (DGGE) and sequence analysis, which identified 11 different plankton taxa that were related to several distant taxonomic groups.

Hephaestia caeni gen. nov., sp. nov., a novel member of the family Sphingomonadaceae isolated from activated sludge.
A Gram-staining-negative, rod-shaped and motile bacterium, designated strain ERB1-3(T), was isolated from a laboratory-scale activated sludge system treating coke plant effluent using thiocyanate-supplemented growth medium and is considered to represent a novel genus and species. Expand
