The green macroalga Dictyosphaeria ocellata influences the structure of the bacterioplankton community through differential effects on individual bacterial phylotypes

摘要: Marine macroalgae are subjected to large numbers of bacteria in their environment. These have the potential affect health and ecology algae a variety ways can be both beneficial harmful algae. Therefore, likely evolved mechanisms differentially regulate growth bacterial species. In this study, we examined effects green alga Dictyosphaeria ocellata on bacterioplankton community field enclosure experiments individual, naturally co-occurring strains laboratory co-culture experiments. experiments, compared communities enclosures with without D. using denaturing gradient gel electrophoresis found that significantly changed composition. Seven phylotypes were eliminated presence five exclusively alga. We also algal-treated water development within no change Laboratory revealed extracts individual species-specific manner responsible for these differed by
