Interested in the ecology of nonpathogenic freshwater bacteria, their microdiversity, co-existence with other microorganisms and factors explaining their life in the water. Focused to the Limnohabitans genus (Betaproteobacteria) regular members of lakes, reservoirs and (fish)ponds. Isolated more than 50 strains from different habitats. Recently, studying their photosynthetic capability in environmental samples as well as in laboratory cultures. Also, analysing sequenced genomes for the common metabolic traits and differences of the Limnohabitans strains. Areas of competence: aquatic microbial ecology, microbial cultivation and isolation, DNA extraction, PCR, sequences alignment, phylogeny, Fluorescence in situ Hybridization, genome sequencing, assembly, annotation and analysis ResearcherID: AAC-2903-2021 or F-8578-2014 Scopus Author ID: 13408103000 Loop profile: 846891 ORCID: 0000-0002-9132-8321 Education: 2006 to 2012: Ph.D. study in Hydrobiology, Faculty of Science, University of South Bohemia, České Budějovice.
