The present study aimed to find a potential dye decolorizing ligninolytic bacterial consortium for the degradation of azo dye mixture with the generation of electricity in a dual-chambered microbial fuel cell. In the present study, the bacterial consortium WGC-D was investigated for its ability to produce electricity with the degradation of azo direct dye mixture.

: In this study, amino acid functionalized poly(2-hydroxyethyl methacrylate-N-methacrylolyl-l-phenylalanine) [PHEMAPA] cryogel discs were prepared. In this respect, phenylalanine containing N-methacryloyl-(L)-phenylalanine methyl ester (MAPA) was polymerized with 2-hydroxyethyl methacrylate (HEMA) without requirement of any activation step. Laccase bound poly(2-hydroxyethyl methacrylate-N-methacryloyl-l-phenylalanine) [Lac-PHEMAPA] cryogel discs were applied for decolorization of Reactive Blue-247 (RB-247).

In this study, we used traditional methods to isolate and screen for fungal laccases that have potential for use in the textile industry (dye decolorization) and a molecular marker to identify studied samples. Fifteen strains of basidiomycetes were isolated and screened for laccase activities on phenol, guaiacol and RBBR. Five strains showed positive laccase activities on all three substrates.

Azo dyes are commonly used in many commercial industries. 16 bacterial isolates were isolated from textile effluents, of which 4 isolates (HB1, HB2, HB3 and HB4) showed ability to decolorize Trypan blue dye. Based on the standard morphological and biochemical characteristics, HB3 isolate that showed maximum decolorization of Trypan blue was identified as Bacillus sp. HB3 isolate showed 96.6 % decolorization of Trypan blue within 24 h of incubation.

Fifty yeast isolates from different habitats nearby a textile factory in Menoufia governerate, Egypt were screened for their ability to decolorize the azo dyes direct red 81 (DR81) and reactive brilliant red X-3B (RBR). Out of those, twenty two isolates displayed positive results therefore they were characterized morphologically and physiologically. The most active two were identified as Meyerozyma guilliermondii and Naganishia diffluens on the bases of 28S ribosomal RNA sequencing. The bio degradation of the dyes was confirmed by UV-visible spectra and IR analysis.

Isolation and identification of the bacteria from textile effluent and evaluation of their ability to decolorize toxic sulfonated azo dye, Direct Red 81 were studied. A total of four bacterial strains were isolated from textile wastewater and their decolorizing activity was measured spectrophotometrically after incubation of the isolates for 24 h. in mineral salt medium modified with 100 ppm Direct Red 81 and supplemented with yeast extract. The bacterial strains were identified belonging to Raoultella planticola strain ALK314 (DR1), Klebsiella sp.

The research objective of the thesis is to select microorganisms capable of producing laccase, laccaselike from Ba Vi National Forest area, in herbicide / dioxin contaminated soil at Bien Hoa airport. Assessing the ability of decomposing herbicides containing dioxin and reactive dyes by laccase, laccase-like and VSV strains were selected to guide the application in defense activities.
