Figure 2

Cell viability detected in mouse fibroblast cells (NCTC clone 929) in the presence of different concentrations (g/L) of BS1, BS2, BS3, BS4, and BS5, compared to the positive control (phenol) and negative control (DMEM, 0 g/L biosurfactant). Results were expressed in percentage compared to the negative control. The dotted line indicated the limit (70%) of cytotoxicity according to UNE-EN-ISO 10993-5 standard, whereas the solid line marked 90% of cell viability, indicating the mild cytotoxicity.
