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 syst… Show more

“…Segundo Rodrigues et al (2011), os micro-organismos assumem estratégias ecológicas para a assimilação de um substrato: uma delas é o cometabolismo. Segundo Khelifi et al (2009) Wolicka et al (2009), a utilização de apenas uma espécie de micro-organismo na biodegradação de solos…”

“…As variáveis foram obtidas utilizando os métodos descritos por APHA 2005, exceto corante, que ocorreu segundo método descrito por Rodrigues et al (2011), com uso de espectrofotômetro UV VIS e leitura de absorbância a 610 nm (cor real).…”

“…Thus, the use of fungi for the treatment of effluent can be an alternative due to the ability of these microorganisms to mineralize compounds pollutants through the production and release of non-specific extracellular enzymes with high oxidative power, which are responsible for the biodegradation, transformation, and reduction of dye toxicity 7 . The complete mineralization of textile dyes by biological treatments is still a challenge, since in most cases the rupture of the azo bond occurs without efficient degradation of other components of structures of the dye molecule, which still results in the presence of compounds that can have harmful effects on the environment 8 . In order to optimize the mycoremediation process for highest mineralization of azo dye congo red, Phanerochaete chrysosporium, a potent white rot fungus, was used in sequencing batch reactors arranged in series.…”
