Donor oysters enriched microbial content of the seawater. a Bacterial 16S relative quantification (y-axis) of the control (blue) and ME seawater (purple) at day 2 of the exposure (x-axis). *Represents statistical significant differences between conditions: unpaired t-test with Welch’s correction, p-val = 0.001. b The Chao1 index (y-axis) from 16S barcoding analysis performed on the bacterial community of the control seawater (blue) and ME seawater (purple) sampled at day 2 of the exposure (x-axis). *Represents a statistically significant change in Chao1 index in the ME compared to the control seawater, i.e, ANOVA, p-val < 0.05. c Bar graph of cumulative CFU per mL (y-axis) of cultivable bacteria sampled in seawater until day 10 in the three tanks used in the control seawater (blue) and ME seawater (purple) (x-axis). *Represents a significant statistical difference in the ME compared to the control seawater, i.e., Wilcoxon test, p-val < 0.05
