Název v původním jazyce

Grazer and virus-induced mortality of bacterioplankton accelerates development of Flectobacillus populations in a freshwater community

Popis výsledku v původním jazyce

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 weredetected. 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 virusesand 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.
