“…aeuroginosa strain BCH showed the inductive pattern of oxidoreductive enzymes laccase, azo reductase and NADH-DCIP in the degradation of textile effl uent (Phugare et al 2011b). It has also been reported that fungal lignin peroxidases show higher oxidative degradation potential towards azo dyes (Parshetti et al 2007, Pasti-Grigsby et al 1992). …”

“…The role of such enzymes from various fungi, bacteria as well as their consortium have been well documented in biodegradation of textile dyestuff and effl uent (Parshetti et al 2007, Lade et al 2012. In order to get the additional insight into the degradation process by the fungal-bacterial consortium, the activities of crude oxidoreductive enzyme were monitored.…”

“…The removal of acidic dye from an aqueous solution by sorption on dead fungus biomass was also reported (Kahraman et al 2012). Alternately, decolorization of textile effl uent by microorganisms such as fungi, bacteria as well as their consortium have been shown highly effi cient with the generation of less-toxic degradation metabolites (Parshetti et al 2007, Kalyani et al 2008, Lade et al 2012.…”

Abstract:In the present study, the enrichment and isolation of textile effl uent decolorizing bacteria were carried out in wheat bran (WB) medium. The isolated bacterium Providencia rettgeri strain HSL1 was then tested for decolorization of textile effl uent in consortium with a dyestuff degrading fungus Aspergillus ochraceus NCIM 1146. Decolorization study suggests that A. ochraceus NCIM 1146 and P. rettgeri strain HSL1 alone re moves only 6 and 32% of textile effl uent American Dye Manufacturing Institute respectively in 30 h at 30 ±0.2°C of microaerophilic incubation, while the fungal-bacterial consortium does 92% ADMI removal within the same time period. The fungal-bacterial consortium exhibited enhanced decolorization rate due to the induction in activities of catalytic enzymes laccase (196%), lignin peroxidase (77%), azoreductase (80%) and NADH-DCIP reductase (84%). The HPLC analysis confi rmed the biodegradation of textile effl uent into various metabolites. Detoxifi cation studies of textile effl uent before and after treatment with fungal-bacterial consortium revealed reduced toxicity of degradation metabolites. The effi cient degradation and detoxifi cation by fungal-bacterial consortium pre-grown in agricultural based medium thus suggest a promising approach in designing low-cost treatment technologies for textile effl uent.

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 ).Keywords: Aspergillus niger; sequential batch; congo red. INTRODUÇÃOOs corantes sintéticos do tipo azo (-N=N -) representam cerca de 70% do mercado mundial de corantes, sendo estimada a perda em cerca de 10 a 20% de sua massa, principalmente nas etapas secundárias de beneficiamento têxtil, 1,2 o que resulta em preocupação ambiental quando do descarte inadequado dos efluentes têxteis, pois estes corantes possuem como característica a persistência no meio ambiente. 3A presença de corantes têxteis em corpos hídricos receptores predispõe à toxicidade a vida aquática e diminui a transparência de água, afetando o processo de fotossíntese e a concentração de oxigênio dissolvido que é essencial à biota. 3,4 Vários processos físico-químicos têm sido utilizados visando o tratamento destes despejos -coagulação, seguida de flotação ou sedimentação, adsorção em carvão ativado, 5 processos oxidativos avançados, 6,7 sistemas eletroquímicos, 8 entre outros. Porém, esses processos apresentam custo elevado e baixa eficiência para remoção de cor e matéria orgânica dissolvida, além de não serem destrutivos, o que faz com que a disposição da fase sólida se constitua em outro aspecto negativo do tratamento físico-químico. [7][8][9] Em relação aos processos biológicos, os sistemas anaeróbios e aeróbios -fundamentados na ação de bactérias -podem alcançar bons níveis de eficiência quando utilizados em conjunto, mas, separadamente, não apresentam percentuais de remoção satisfatórios.10,11 Em ambiente anaeróbio, a partir da clivagem da molécula do corante, são formadas aminas aromáticas cancerígenas, que são ainda mais difíceis de serem degradadas, exigindo o pós-tratamento do efluente em unidades aeróbias, 12,13 como, por exemplo, o sistema de lodos ativados, que é muito empregado para o pós-tratamento desses efluentes. Mas esse sistema, apesar dos bons resultados em relação à remoção de cor, apresenta produção de lodos elevada e é susceptível a choques de carga orgânica. 14,15 Apesar de recente, em comparação com outros sistemas biológi-cos, a utilização de fungos na biorremediação de poluentes tem sido relatada na literatura especializada devido ao potencial enzimático desses micro-organismos. 16As espécies de Aspergillus são conhecidas por sua capacidade de utilizar de corantes como substrato, transformando-os em compostos não tóxicos ou de baixa toxicidade, 17,l8 o que ocorre pela produção de enzimas e...

“…Among the low-cost and viable alternatives available for effluent treatment, biological processes are recognized by their capacity to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) [9]. Several microorganisms, including fungi, bacteria, yeasts and algae, can decolorize and even completely mineralize azo dyes under certain environmental conditions [10].…”

In continuation of our studies on single fungal cultures, this study was aimed to investigate the potential of mixed culture of two indigenous white rot fungi Pleurotus ostreatus IBL-02 and Coriolus versicolor IBL-04 to decolorize and detoxify the dye based textile effluent collected from Sitara Textile Industry (SIT), Faisalabad, Pakistan. Different pHysical and nutritional factors were optimized to enhance the efficiency of mixed culture for SIT effluent color removal. Under optimum conditions, the mixed culture completely decolorized (100%) the effluent in 2 days using glucose and urea as carbon and nitrogen sources, respectively in 30:1 ratio. The mixed culture produced all the three major liginolytic enzymes like lignin peroxidase (LiP), manganase peroxidase (MnP)
