Table 2.
Biomass productivity of axenic (AX), laboratory (LAB) and unibacterial cocultures of Tetraselmis suecica F&M‐M33 performed in vitamin‐added and vitamin‐free culture media. The ratio of bacterial concentration at the end compared with the start of the trial is also reported for both culture media. For the same parameter, along the row, the same superscript letter indicates significant difference (P < 0.05). No significant differences for biomass productivity were found along the columns, except for AG2 in vitamin‐free medium. The taxonomic identification of the bacteria indicated here by their codes is reported in Table 3. na = not applicable
