Values represent the mean from three independently repeated experiments (each with three elementary replicates) ± SE
¹Within a column, Δ symbols indicate a significant difference between the values of each modality and the control as indicated by Newman–Keuls multiple range tests applied to the diameter values (P < 0.05)
