3.7 Cytotoxic activity of colorants
The cytotoxicity of the colorants was evaluated using the
AlamarBlueTM assay against MRC-5 cells. The results
obtained show the percentage of the number of live cells in the sample.
The cytotoxicity of Clonostachys rosea P2SO329, Penicillium
gravinicasei P3SO332 and Penicillium sclerotiorum P3SO224 ethyl
acetate extracts show an IC50 > 100 μg/mL.
