Effects of salinity on the epibacterial community composition on  the brown alga Fucus vesiculosus
In this study, the response of the microbiota associated with the brown alga Fucus vesiculosus (bladder wrack) and on reference substrata (stones) to different salinity levels with respect to community composition and cell density was analyzed by non-culture-based methods. F. vesiculosus and stones were cultivated at three salinity levels (5, 19, and 25) and after two weeks their biofilm was sampled for analysis of the 16S rRNA gene. Shifts in the bacterial community composition were observed  by 454 pyrosequencing.
