Figure 3.

The antifouling effect of antifouling coating developed by incorporating the bacterial EPS into epoxy primer along with epoxy resin and hardener. (A) Recruitment of marine foulers on the reference and plates coated with bacterial EPS submerged in the marine environment for a period of 50 days. (B) The plot shows the inhibiting effect of antifouling coatings.
