Mean of two samples (standard deviation). Each sample was analyzed in triplicate. abcd Means with different letters in the same line differ significantly (p < 0.05) according to the Tukey test. * Means followed by an asterisk differ significantly (p < 0.05) from the control sample (FC) according to the Student’s t-test.
