Laccase can
decolorize various dyes like azo, anthraquinone and triphenylmethane, through free radical mechanism by creating phenolic compounds.
It could effectively
decolorize up to 100 mg/L of Reactive Violet 5 (100%) within 16 h and is decreased to 63%, when dye concentration increased to 800 mg/L and decolorization time increases from 16 h to 38 h, respectively.
The present study reveals the ability of the Castellaniella denitrificans to
decolorize Malachite Green.
The remaining dark-colored, nutrient-deprived stream, after exposure to advanced oxidation via Ti[0.sub.2]-mediated photocatalysis, would
decolorize due to degradation of the color-causing compounds and recalcitrant organics.
kingae are Gram-negative bacilli with flat ends in pairs or short chains, though they may resist decolorizing or
decolorize unevenly (1, 27, 30) (Table 2).
The electrochemical treatment was also used to
decolorize the exhausted reactive dyebath and washing effluents, the reuse of which provided excellent red and yellow dyeing textiles [6,7].
Acetone was then used to
decolorize the smear for a few seconds after which the smear was washed under clean running tap water.
Many reseachers have tried to isolate microorganisms, which have the ability to
decolorize melanoidins.
Recent preliminary work at FPInnovations--Forintek Division (unpublished) showed that UV light could partially
decolorize blue stain and also induce the typical aged pine color that helps mask residual blue stain.
Both carbohydrate and protein content was stimulated over control in presence of all the dyes suggesting that textile dyes might have induced protein synthesis in order to
decolorize the textile dye (Table II).
has received a patent for a coating composition comprised of a hardenable film-former and an effective amount of a reducing agent having a redox potential sufficient to
decolorize an iodine or iodophor stain on the film-former.
Today, professional whitening techniques go to work on the tooth structure itself, using peroxide to oxidize and
decolorize gray and yellow tooth pigments.
