| Research Abstract |
Single cell-level analysis of bacterioplankton in Tachibana Bay and Ariake Sea in summer 2010-2012 revealed that the bacterial cells were highly respiratory active in the upper layers with lower salinity, higher water temperature and higher concentrations of chlorophyll a and dissolved organic carbon (DOC). Furthermore, DNA finger printing and cloning of bacterial communities associated with Chattonella antiqua/marina cultures suggested that the phycosphere bacterial community was diverse and included gamma- and alpha- proteobacteria, seemingly growing on hydrophilic DOC derived from the growing algae.
