MTT assay for assessing cell viability. Human lymphoma (U937) and myeloid leukemia cells were cultured up to 48 hours with BES buffer (buffer), culture filtrate of CF294 displaying a laccase activity of 3.5 U/mL (CF294), 150 ng of AFB1 incubated for 72 h with the culture filtrate of CF294 displaying a laccase activity of 3.5 U/mL (CF294 + AFB1) or with the sole AFB1 (150 ng). All the experiments were performed at least three times and results were expressed as mean ± standard deviation (SD).
