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.
