%X a continuous flow reactor, inoculated with aspergillus niger an400, with total volume of 5 l was operated at 29oc, with eight hours of retention hydraulic time and 150 l.h-1 of air flow rate in order to remove 25 mg.l-1 of congo red dye from a synthetic wastewater. the feeding of the reactor, inoculated with aspergillus niger an400, was done in two phases: phase i, with 0,5 g/l of saccharose and phase ii, with no saccharose. in phase i, it was possible to verify efficiencies of organic matter and color (mg pt.l-1) removal of 80 ¡À 16% and 82 ¡À 10%, respectively. in phase ii, the efficiency of organic matter removal was 75 ¡À 13% and color removal was 89 ¡À 7%. the higher removals of nutrients were achieved by the reactor in phase i with 25% to ammonia, 90% to nitrite, 93% to nitrate and 21% to phosphorus. apparently, the presence of saccharose improved the removal of the nutrients.
