a Concentration of AFB1 detected in the culture medium. Data represent the mean values of AFB1 in 3 replicated cultures ± SD. Values in column followed by different letters are significantly different for P < 0.001 (Tukey–Kramer Multiple Comparison Test).
b Percent degradation of AFB1 calculated as: D (%) = [(Ci−Cf)/ Ci] x 100, where Ci was the concentration of AFB1 in the non-inoculated control and Cf was the concentration of AFB1 in P. eryngii cultures at the given time.
