Enzymatic Removal of dung from hides

摘要

Dung cladding presents problems in the processing of hides into leather. Together, cellulose, hemicellulose and lignin comprise 80/100 of the composition of bovine dung, which reflects the lignocellulose content of vegetable fodder. Dung is attached to the hides by physical entrapment in the hairs forming a 3-dimensional matrix with the hair. Removal of dung from hide pieces was effected by the action of cellulase, xylanase and laccase separately over 20-24 hours.
