Abstract The libraries of bacterial 16Sr RNA gene fragment from algal–bacterial consortia of the White Sea coastal zone are analyzed. Up to 3% of the reads have revealed to correspond to eukaryotic rRNA . They related to following main eukaryotic clades: Discoba, Stramenopiles, Ciliata, Amoebozoa, and Nucletmycea. Amoebae, especially Vermamoeba , were present in all samples. In one sample, heterolobose amoeba Paravahlkampfia was detected. These microorganisms are parasites of microalgae, which can induce significant damage to industrial cultures. However, the data on their physiology and distribution are scarce. This study provides new evidence about the diversity of herbivorous eukaryotic microorganisms in natural algal‐containing consortia.
