Values in parentheses represent cultivation times that are required for reaching the maximum values; ±, SD from three independent experiments; Different letters represent significant statistical differences between CMUWF1−2 and AF2.5 of each parameter in the same FF concentration according to Student’s t-tests with p < 0.05
