| titleOfInvention | Preparation method of dehairing enzyme preparation and application of dehairing enzyme preparation in dehairing of cattle hide |
| abstract | The invention relates to a dehairing enzyme in leather production, in particular to a preparation method of a dehairing enzyme preparation and application thereof in dehairing of cattle hide. The preparation method of the depilatory enzyme preparation comprises inoculating Bacillus subtilis CGMCC No.14836 into fermentation culture medium for fermentation, and fermenting when OD is obtained 600 When the value is 0.5-1, adding an inducer IPTG, regulating the rotating speed to 250-300 r/min, culturing for 40-44 hours, and terminating fermentation to prepare fermentation liquor containing the unhairing enzyme; centrifuging the fermentation liquid containing depilatory enzyme, collecting supernatant, and adding antiseptic to obtain depilatory enzyme liquid preparation. The invention solves the defects that the conventional enzyme depilation needs to be cooperated with other enzyme preparations or chemical auxiliary agents for depilation, the depilation time is long, the control is not strict, and the grain surface is still easy to be damaged. Has the advantages of equivalent unhairing effect to that of the traditional grey alkali method, superior physical performance to that of the grey alkali method, soft hand feeling of the finished leather and the like. |
