Cytotoxicity assays and chromatography results from liquid and solid culture media of Lentzea sp. CC55. (a) Dashed line boxes highlight the highest cytotoxic effect on NCIH460 cells related to a reduction in cell viability. Null, moderate and high cytotoxic effect can be observed as red, orange and green circles at the top of the bioactivities. (b) Comparison between chromatograms from extracts from liquid BG and BS media that presented cytotoxicity and their counterparts from solid media with no bioactivity. Presence (green) or absence (red) of peaks in chromatograms related to bioactivities are shown at the top with green and red circles, respectively. Rt, retention time. mAU, milli-absorbance unit
