METHOD OF DEGREASING SHEEPSKIN-FUR RAW MATERIAL Russian patent published in 2009 - IPC C12S7/00 C14C1/08 C14C5/00 

FIELD: chemistry.

SUBSTANCE: method involves degreasing sheepskin-fur raw material and can be used in fur production during degreasing of sheepskin-fur coat and fur raw material. Processing of the raw material is carried out in a degreasing bath containing a bacterial suspension, which has both lipolytic 50-60 units/gram and proteolytic 8-10 units/gram activity, with the total product of life activity of the microorganisms at a value of 5-6 g/dm³, synthetic surface-active substance - 0.5-1.0 g/dm³, catalase-positive procariotic culture of genus Erwinia sp. in the quantity 10⁹-10¹⁰ cells/cm³ in the degreasing bath hydrogen peroxide is additionally added in the quantity 0.1-1.0 g/dm³, preliminarily dissolved in a tenfold amount of piped water. Processing is carried out at a temperature of 40±2°C, for 60 min., with some mechanical action from time to time and liquid crystallisation=10.

EFFECT: increase in quality of degreasing sheepskin and reduction in the level of toxic sewage production.
