The effect of pH on the decolourization of Vat dyes
by garlic peroxidase was monitored by incubating the reaction mixture (as in assay section) using buffers of different pHs; 0.05 M acetate buffer (pH 3.5-5.5); 0.05 M sodium phosphate buffer (pH 6.0-75); and 0.05 M Tris-HCL buffer (pH 8.0-10) at 50[degrees]C for 4h.
The selection of the type of semiconductor is based on its ability to convert the vat dyes
into nontoxic products [44, 90,177,178].
The use of the function proVAT is recommended for dyeing cotton with vat dyes
. This special feature prevents the penetration of atmospheric oxygen so that the use of hydraulic and brine can be optimized.
Open width stable continuous dyeing of cotton, linen and their blends through disperse, reactive, vat dyes
Some of these dyes are- Acid (Anionic) dyes, Basic (Cationic) dyes, Neutral - Premetalized dyes, sulfur dyes, vat dyes
, reactive dyes, pigment dyes, etc.
are popular for all shades in Europe, e.g.
