Herbicide Inhibition Through Artificial EPS In the first experiment we observed a positive correlation of the total EPS with the EC50-values (Figure 7A ), in the second experiment, a highly significant positive correlation between the mean EC50-values of N. palea biofilms toward Prometryn and the total artificial EPS-content was found with R 2 = 0.99 ( p < 0.01) (Figure 7B ).
