Abstract: Industries of tapioca starch produce several billion litres of coloured, often toxic and harmful wastewaters over the world annually. Those effluents have strong concentrations of COD (10-200 g l-1), phenol and its derivatives (0.5-8 g l-1) and often contain proteins, cyanides, chlorinated lignin compounds and dyes. The large amount of lignin derivatives of these effluents is responsible of their dark-brown colour. The phenolic compounds of such wastewaters exert some bactericidal effects on wastewater treatment plant (WWTP) microorganisms. Fungal treatment of these effluents under aerobic conditions makes it possible to obtain phenol reduction (51-100%), good decolourisation (31-100%), biochemical oxygen demand (BOD) reduction up to 85.4%, and enzyme production. In the present work an attempt has been made to treat the tapioca sago effluent by the fungi Gliocladium roseum. The result shows that the fungi have ability to reduce the pollutants in the waste and can be employed for the treatment to yield good efficiency.
