Abstract

This is the first study to apply a comparative analysis of environmental parameters, phytoplankton pigment data, and bacterioplankton community structure combined with 16S rRNA clone libraries in an Emiliania huxleyi bloom assemblage, as revealed by denaturing gradient gel electrophoresis (DGGE) and clone libraries. With the majority of the DGGE phylotypes identified, domination by Flavobacteria in the particle-associated bacterial assemblage and by Alfaproteobacteria and SAR86 in the free-living bacterial assemblage was apparent. Stations showed distinct bacterial assemblages, as indicated by ordination of the bacterial community composition. Moreover, changes in particle-associated bacterial assemblage detected by DGGE were weakly yet significantly correlated with changes in phytoplankton community composition.
