Description
| - We analyzed the effects of distinct bacterial mortality factors, viral lysis and heterotrophic nanoflagellates (HNF) bacterivory, associated with the development of filamentous Flectobacillus populations. Reservoir bacterioplankton were subjected to additions of both HNF and viruses together, or HNF alone, and then incubated in situ in dialyses bags. For distinct bacterial groups, mortality or growth stimulation was analyzed and bacterial groups vulnerable to HNF predation or discriminated against were detected. Bacterial lineages most vulnerable to virus-lysis were also identified. Filaments affiliated with the Flectobacillus cluster appeared in both treatments with HNF, but were about twice as abundant, long and active as in incubations with viruses and HNF as compared to HNF alone. Viruses appeared to selectively suppress several bacterial groups, perhaps enhancing substrate availability thus stimulating growth and activity of filamentous Flectobacillus.

- Studovali jsme vliv predace prvoků na bakteriích a jejich mortalitu navozenou virovou lyzí, které ovlivnily různě rozvoj populace vláknitých bakterií rodu Flectobacillus. Bakterioplankton z přehradní nádrže byl obohacen přídavky heterotrofních bičíkovců a virů současně, nebo pouze bičíkovci a potom inkubován v dialyzačních pytlích. Pro různé bakteriální slupiny byla stanovena mortalita způsobená těmito faktory nebo případná růstová stimulace. Tak byly určeny skupiny bakterií, které byly selektivně vyžírány nebo ty, které byly napadeny viry. Vláknité bakterie rodu Flectobacillus se objevily v obou variantách s bičíkovci, byly však mnohem početnější, větší a aktivnější ve variantách obohacených jak prvoky, tak i viry. Ukázalo se, že viry selektivně odstranily některé skupiny bakterií, čímž se zvýšila dostupnost substrátu a došlo ke stimulaci růstu vláken rodu Flectobacillus, které odolávaly jak žíru prvoků, tak i významnějšímu dopadu virové lyze.
