Cytotoxicity of Streptomyces sp. MUM265 extract against human colon cancer cell lines. The cytotoxicity of Streptomyces sp. MUM265 extract against the colon cancer cell lines and non-cancerous CCD-18Co cell measured using MTT assay. Each bar represents the mean of the cell viability of the cell lines after exposure to extract at respective concentrations tested for 72 h (n = 5). The vertical lines associated with the bars represent the SD of the mean. Symbol (*) indicates P < 0.05 significant difference compared to control (0.5% DMSO). Curcumin (3 μg/mL) was used as the positive control
