Title: Process for obtaining enzymes and particularly proteolytic enzymes secreted by microorganisms for use in tanning, skin dressing and the like
IPC: C12N9/50
Filed: 1929-06-04
Abstract: 313,874. Boidin, A. R., and Effront, I. A. June 18, 1928, [Convention date]. Treatment preliminary to tanning.-Enzymes for use in tanning and the like are developed in a nutritive medium containing an addition of 20 to 50 grams per litre of glucides (carbohydrates), said glucides being partially transformed by the micro-organisms and acting as a buffer for the product, for fixing it and increasing its proteolytic power. The proportion of proteic nitrogen in the nutritive medium is reduced by substituting therefor mineral nitrogen. The medium is enriched with alkaline earth or magnesium salts, such as chlorides or sulphates of lime and magnesium, which operate to increase the quantity of secreted proteases and aid the fixing of the product by maintaining the pH value between 6 and 7, or the secretion of proteases is increased by intensively aerating and compressing, with alternating pressure and expansion or pressure and vacuum. The increase of power of the macerating substances thus obtained permits the amount of enzyme, or the time of duration or the temperature in the maceration and depilation operations to be reduced. An example of the use of these enzyme solutions is given using a temperature of 28-30‹ C. for maceration, and 15- 17‹ C for depilation. Specifications 21720/95, 12549/98, and 24982/10 are referred to.
