The study aimed to assess the relationship between two strains of the diatom Pseudo-nitzschia and their respective associated bacterial communities under different turbulence conditions. The study focused on the epiphytic bacteria. Two strains P. multiseries and P. fraudulenta were used. The experiments were conducted with the Agiturb turbulence generation system (Le Quiniou et al., 2022).</p><p>The 16S rRNA gene V3-V4 region was amplified and sequenced.
