摘要：

DYE REMOVAL BY USE OF Aspergillus niger AN 400 IN A SEQUENTIAL BATCH REACTOR. A sequential batch reactor (4 L) inoculated with Aspergillus niger was operated in order to remove congo red dye (10 mg L-1). The feeding of the reactor was done to each 7 days. The glucose was added in the concentration of 1 g. L-1 (Stage I) and 0.5 g L-1 (Stage II). The Stage III occurred without glucose addition. The Stage I was great to process, because the system reached the greater dye removal (95%) as well as the kinetic parameters ware the best - K-M (0.7 g L-1) and k(1) (0.025 h(-1)).
