Dye decolorization

Chemical Reactions of Dyes. Decolorization is important for cyanines used ia imaging materials. Understanding decolorization provides clues to dye reactions that may cause degradation of imaging materials duting preparation and storage. For many dyes, protonation of the methine chain occurs readily and reversibly (64). Highly basic carbocyanine dyes like those from benzimidazole (eg, 36) protonate so readily that this provides a practical decolorization method. [Pg.399]

Dye decolorizing potential of the WRF Ganoderma lucidum KMK2 was demonstrated for recalcitrant textile dyes. G. lucidum produced laccase as the dominant lignolytic enzyme during SSF of wheat bran, a natural lignocellulosic substrate. Crude enzyme shows excellent decolorization activity to anthraquinone dye Rema-zol Brilliant Blue R without redox mediator, whereas diazo dye Remazol Black-5 (RB-5) requires a redox mediator [43]. [Pg.162]

Lentinula (Lentinus) edodes produced only Mn peroxidase, and the production of both laccase and lignin peroxidase was, apparently, negligible. Consider that a strict relation between the production of Mn peroxidase and the dye decolorization ability was observed in vivo [13]. [Pg.163]

Decolorization of polymeric dyes Poly R-478 (polyanthraquinone-based) and Poly S-l 19 (azo dye) by immobibzed white rot fungus Crysosporium lignorum CL1 on circular plastic packing material in 2L air-lift fermenter was studied by Buckley and Dobson [47]. They also examined the relationship between polymeric dye decolorization and the production of LiP and MnP activity in its statistically growth... [Pg.173]
