Fur. Fur is bleached to permit dyeing to the desired shade. The coloring matter in fur is usually bleached using hydrogen peroxide stabilized with sodium silicate. For difficult to bleach dark hairs it is necessary to add a step using a reducing agent with a catalyst such as ferrous sulfate. The formula and procedures are the same as those used for wool.

In spite of their catalytic versatility and their capacity to transform a variety of pollutant compounds, peroxidases are not applied at large scale yet. The challenges that should be solved to use peroxidases for environmental purposes have been recently reviewed [146], Three main protein engineering challenges have been identified (a) the enhancement of operational stability, specifically hydrogen peroxide stability (see Chap. 11) (b) the increase of the enzyme redox potential in order to widen the substrate range (see Chap. 4) (c) the development of heterologous expression and industrial production (see Chap. 12). 

Some alkyl hydroperoxides, such as TBHP (/-butyl hydroperoxide), are less sensitive to contamination by metals compared to hydrogen peroxide and percarboxylic acids. However, with the increased knowledge of hydrogen peroxide stabilization, this point is somewhat negated.

Kishimoto et al. [65] treated 4-substituted guaiacyl and veratryl lignin model compounds with acidic hydrogen peroxide stabilized by the addition of DTPA. The reactions were carried out with a three molar excess of peroxide at 70°C in aqueous or aqueous dioxane solution and pHs in the range 1-3. The compounds were more susceptible to attack by peroxide at the lower pHs. Guaiacyl compounds reacted more rapidly than their methylated analogues.
