Enzymatic Polishing of Jute/Cotton Blended Fabrics
Jute is a strong, stiff, natural fiber. When blended with cotton it makes a sturdy but prickly fabric due to protruding surface jute fibers. Samples of jute-cotton blended fabric were treated with commercial cellulases, xylanases and pectinases individually and in combination at various concentrations in order to smooth and soften the fabric. Enzyme treatment was carried out at 50°C in the pres...
متن کاملUltrasonic pilot-scale reactor for enzymatic bleaching of cotton fabrics.
The potential of ultrasound-assisted technology has been demonstrated by several laboratory scale studies. However, their successful industrial scaling-up is still a challenge due to the limited pilot and commercial sonochemical reactors. In this work, a pilot reactor for laccase-hydrogen peroxide cotton bleaching assisted by ultrasound was scaled-up. For this purpose, an existing dyeing machin...
متن کاملPhenol Removal through Combined Biological and Enzymatic Treatments
This work studies the use of biological and combined biological/enzymatic treatments in phenol degradation. The systems studied were conventional batch aerobic biological followed or preceded by enzymatic treatment. Tyrosinase extracted from the mushroom Agaricus bispora was employed. Biological treatment efficiently degraded effluents containing up to 420 mg.L of phenol, removing 97% of the CO...
متن کاملDeactivation of soybean agglutinin by enzymatic and other physical treatments.
The main objective of this study was to eliminate the hemagglutination activity of an antinutritional factor in soybeans, soybean agglutinin (SBA). A series of experiments was designed to enzymatically modify SBA structure and to use other physical treatments to reduce activity. SBA extract was prepared from soy flour and used as the substrate for all treatments. Deglycosylation by enzyme decre...
متن کاملNon-Pharmacologic Treatments for Fear of Flying
The purpose of the present survey was to review the important Non-pharmacologic treatments for fear of flying up to the present. This study is in the same way as some studies. Accordingly, some Non-pharmacologic treatments for fear of flying were assessed through this systematic review article. The general conclusion from the information provided by the former studies, shows that a growing num...
