O’Brien, Anne Marie published the artcileDye bleaching and phenol precipitation by phthalic anhydride-modified horseradish peroxidase, Name: Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate, the publication is Journal of Chemical Technology & Biotechnology (2000), 75(5), 363-368, database is CAplus.
The phenol precipitation and dye bleaching capabilities of phthalic anhydride-modified horseradish peroxidase C (PA-HRP) were compared with those of native HRP C and ethylene glycol bis(succinic acid N-hydroxysuccinimide ester)-modified HRP (EG-HRP) reported previously. The removal efficiency (percentage of phenol removed from solution under exptl. conditions) was determined for native HRP and both modified forms. Removal efficiencies at 37° were very similar, with >95% removal in each case. Removal efficiencies were less at 70° overall (range 25-45%), but PA-and EG-HRP removed up to 50% more phenol than native HRP. The three HRP forms showed similar dye bleaching performance at 37° in the presence of H2O2 and accelerators (up to 86% color removal). PA- and EG-HRP showed slightly greater bleaching abilities at 65° than native HRP for some of the dye/accelerator combinations tested. Modified HRPs performed better in 40% (volume/volume) mixtures of dioxane or DMF.
