Bioremediation of Textile Azo Dyes by Trichophyton rubrum LSK-27

Abstract

The potential of a recently isolated wood-degrading fungus, Trichophyton rubrum LSK-27, for effective decolorization of textile azo dyes was evaluated. Within two days of dye addition, the fungus was able to decolorize 83% of Remazol Tiefschwarz, 86% of Remazol Blue RR and 80% of Supranol Turquoise GGL in liquid cultures. The reactive dyes, Remazol Tiefschwarz and Remazol Blue, were removed by fungal biodegradation, while decolorization of the acid dye, Supranol Turquoise GGL, was accomplished mainly by bioadsorption. Therefore the fungus proved to be efficiently capable of both biodegradation and biosorption as the major dye removal mechanisms. The extent of biodegradation was associated with the levels of the extracellular ligninolytic enzymes such as manganese peroxidase and laccase.

Pollutants Biodegradation by Fungi

“…isolated from textile effluent, was investigated for Remazol Yellow, Remazol Orange [212], Remazol Brilliant Blue R (RBBR) (73), Neutral Brilliant Blue GL, and Acid Blue B (89), obtaining decolourization rates ~100% [213,214,215]. Also, Trichophyton rubrum LSK-27 was able to decolourize 83% of Remazol Tiefschwarz, 86% of Remazol Blue RR (90) and 80% of Supranol Turquoise GGL in liquid cultures [216].…”

“…Effluents containing synthetic dyes are hazardous to ecological systems and public health [2,3]. Due to these concerns, the removal of dyes from wastewaters has received considerable attention [4].…”

Biodegradation of Direct Red 5B, a textile dye by newly isolated Comamonas sp. UVS

“…Large amounts of structurally different dyes are used for textile dyeing and around 10-15% of all dye is directly lost to wastewater [1]. The effluents from textile and dyeing industries have high BOD, COD, color, pH, and also it contains metal ions, hence it is very difficult to treat such effluents [2].…”
