Values are means and SE. Significant differences between the samples are indicated by different lower case letters; samples that are significantly different from each other have no letter in common. P< 0.05 was regarded significant, analyzed by the Kruskal–Wallis test, and followed by post hoc comparison according to Conover. n ≥ 50 cells per growth medium.
