Different letters (a, b, c, d, e, f, g, h) indicate significant differences (p < 0.05) between samples. OH (open husk); CH (closed husk) samples. As: asymptotic value of the maximum absorbance value (adimensional); µmax: the maximum growth rate (h−1); λ: lag phase (h), I: percentage inhibition of E. coli (%); and RMS: root mean square (%).
