US Patent 5,834,299Īrchana G, Pillai P (2012) Biochemical characteristics and possible mechanism of proteases for dehairing of hides biotechnology of microbial enzymes. Results were also validated on large scale with goat skins and cow hides.Īnderson LP (1998) Methods for dehairing of hides or skins by means of enzymes. tensile strength, elongation, and tear strength of dyed crust of enzymatically and conventionally dehaired pelts were comparable. Enzymatic dehairing resulted in complete and uniform fiber opening in the dermis and corium region. The microscopic observation of the cross-section of dehaired goat skin and cow hide showed absence of epidermis, hair shaft with empty follicles. In addition, the grain was clean and without damage in enzymatically dehaired pelts. The dehaired pelt showed smooth and white appearance due to hair removal along with epidermal layer. Complete hair removal of skin/hide by the protease achieved in 16–18 h. In addition, the crude enzyme exhibited other enzyme activities such as chondroitinase, laminarase, and chitinase. The crude protease preparation was active toward keratin-azure, elastin-orcin, azocasein, and azocoll, but did not show true collagenase activity. Alkaline protease from Conidiobolus brefeldianus was efficient in unhairing various types of skins and hides.
