Producing Keratin Hydrolysates from Sheep Wool
Manuscript describes producing keratin hydrolysate from sheep wool through two-stage technology whose principle consists in first having wool processed in an alkaline environment during the first stage, and then effecting hydrolysis in the second stage through the action of proteolytic enzyme. Experiments were planned in accordance with factor schemes of 23 types in which factors under study we...

متن کاملFunctional Dyeing of Wool with Natural Dye Extracted from Berberis vulgaris Wood and Rumex Hymenosepolus Root as Biomordant
In this study, a functional colorant, Berberine, extracted from Berberis vulgaris wood was applied onto wool fiber using the extract of roots of Rumex Hymenosepolus as biomordant. The effect of treatment variables on the color strength of dyed fibers was examined. The fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. Dyed samples were tested for an...
متن کاملDerivatives of Keratin
In an earlier paper the authors (1) expressed the view that keratins are fibrous proteins whose characteristic properties are essentially determined by the S-S groups of cystine which act as very firmly established cross links uniting the elementary fibers of polypeptide chains. This view was based on the action of certain alkaline reductants which could be shown to reduce disulfides and conver...
متن کاملRemoval of Pb(II) from water using keratin colloidal solution obtained from wool.
The aim of this study is to investigate the use of keratin colloidal solution, which was obtained from wool, for the removal of Pb(II) from water. The addition of keratin colloidal solution (15 g L(-1), 0.30 mL) to a Pb(II) solution (1.0 mM, 0.90 mL, pH 5.0) resulted in the formation and precipitation of a Pb-keratin aggregate. Measurement of the Pb(II) and protein concentrations in the superna...
