Název v původním jazyce

Response of Alteromonadaceae and Rhodobacteriaceae to glucose and phosphorus manipulation in marine mesocosms

Popis výsledku v původním jazyce

Microbial successions were studied in experimental mesocosms of marine water with additions of organic carbon (glucose), phosphorus (P) or both. P addition lead to pronounced phytoplankton blooms and to enhanced bacterial production. Characteristic succession patterns were observed for two phylogenetic groups of bacteria. There was an initial bloom of bacteria affiliated to the Alteromonadaceae but they rapidly declined with the appearance and bacterivory of heterotrophic nanoflagellates. However, theirpersistence in the microbial assemblages was significantly favored by the additions of glucose. Bacteria affiliated to Rhodobacteriaceae formed a dominant component of the experimental assemblages in treatments with addition of P. We suggest that the observed succession patterns reflect different niche preferences: Alteromonadaceae rapidly responded to allochthonous glucose input, whereas Rhodobacteriaceae benefited from the phytoplankton bloom.
