Abstract
The bacterioneuston is the community of Bacteria present in surface microlayers, the
thin surface film that forms the interface between aquatic environments and the
atmosphere. In this study we compared bacterial cell abundance and bacterial
community structure of the bacterioneuston and the bacterioplankton (from the
subsurface water column) during a phytoplankton bloom mesocosm experiment.
Bacterial cell abundance, determined by flow cytometry, followed a typical
bacterioplankton response to a phytoplankton bloom, with Synechococcus and high
nucleic acid (HNA) bacterial cell numbers initially falling, probably due to selective
protist grazing. Subsequently HNA and low nucleic acid (LNA) bacterial cells
increased in abundance but Synechococcus did not. There was no significant
difference between bacterioneuston and bacterioplankton cell abundances during the
experiment. Conversely, distinct and consistent differences between the
bacterioneuston and the bacterioplankton community structure were observed. This
was monitored simultaneously by Bacteria 16S rRNA gene terminal restriction
fragment length polymorphism (T-RFLP) and denaturing gradient gel electrophoresis
(DGGE). The conserved patterns of community structure observed in all of the
mesocosms indicate that the bacterioneuston is distinctive and non-random.
