Remoção de corante por uso de Aspergillus niger AN400 em reator em bateladas sequenciais

Abstract

Recebido em 28/5/10; aceito em 25/1/11; publicado na web em 1/4/11 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).
