Abstract

We have previously shown that there is a consistent and reproducible bacterioneuston community in the surface microlayer during a fjord mesocosm experiment. One possible cause of the surface microlayer-specific bacterial community is a surface microlayer-specific protist community selectively grazing on the bacterioneuston. We determined protist community structures using Eukarya 18S rRNA gene denaturing gradient gel electrophoresis (DGGE) and subsequent DGGE band sequencing using DNA samples that were collected from the surface microlayer and subsurface water of the mesocosms. As with bacterial communities, protist community structure was consistently different in the surface microlayer when compared with subsurface water. In particular, the protist community in the surface microlayer was dominated by Cercozoa, which were not detected in the subsurface water, and Ciliophora
