recombinant DyP is partially inactivated during successive batches even by continuous fed-batch supply of H2O2, initial recombinant DyP activity is inactivated by 15% over the first 10 min during dye decolorization and remains stable thereafter at 85% of the initial activity from 10 to 40 min
the activity of recombinant DyP immobilized in synthesized silica-based mesocellular foam drops by 6% and 12% at pH 3.0 andpH 4.0, respectively, while the activity decreases by 35% and 70% at pH 5.0 and pH 6.0 after daily leaching treatment
the enzyme shows high compatibility with EcoVax and Dipex as laundry detergents for 48 h at 40C. The enzyme is highly stable against perfume and anti-redeposition agents, particularly 50 mM Na2CO3, and of cationic and other detergent compound, retaining 95, 104, 107, and 125% of its initial activity after treatment with 1% perfume, 50 mM hexadecyltrimethylammonium bromide, 1% (w/v) sodium tripolyphosphate, and 50 mM Na2CO3, respectively.
