Özet

The dehairing effect of 2 keratinolytic enzyme preparations from liquid cultures of Bacillus cereus IZ-06b and B. cereus IZ-06r and 3 commercial proteolytic enzyme formulations used in leather manufacturing for soaking, dehairing, and bating processes were quantified by a computerized force sensor. Measurements of the force needed to remove individual hairs from skin, showed that the keratinolytic enzymes did loosen hairs from sheepskins. These enzyme preparations may therefore be useful alternatives to present days' beamhouse chemicals, although the traditional dehairing procedure with lime and sulphide still exhibited the strongest effect in hair loosening.
