Clearage of Wastewater from Dyeing Industry by the Fungus C. polymorpha

Abstract

A treatment of an industrial wastewater containing disperse dye with the fungus Cunninghamella polymorpha was investigated. The resting fungus cell increased the transparency value of the wastewater from 21 degrees to 43 degrees in 6h. The clearage rate was 1.7 degree (g-wet cell)^-1 h^-1. On the contrary, the sterilized cell was unable to increase the transparency. The clearage of the wastewater was due to sorption of disperse dye by the fungus cell.
