Note that the experiment with M. adhaerens was carried out independently from V. thalassae and P. carrageenovora, both with their own negative control treatment of axenic M. polymorphus. Values in parentheses are the experimental days affiliated with each corresponding growth phase and those in bold are significantly different to their axenic counterparts. Values are the means ± standard deviations of triplicate treatments.
