The result of fermented fungi T. reesei was extracted with ethyl acetate. Ethyl acetate extract was tested against cell lines using the MTT assay. The result of cytotoxic selectivity test with lowest IC50 price, then apoptosis test with double staining acridine orange-ethidium bromide method was performed Ethyl acetate extract fermented from T. reesei has cytotoxic ability against tumor cell lines (WiDr, T41, T47D, Raji) and is not toxic to normal cell lines (Vero). The test sample can spur apoptosis process on colon cancer cells Widr. %@ %U https://japsonline.com/bib_files/abstract.php?article_id=japs2732 %P 151-157
