It was found that the stability of trypsin is higher than the stability of terrilytin in immobilization on cellulose or polyester fibre material in a composite with polyethylene oxide with a molecular weight of 1.5, 4, or 6 kDa. The optimum compositions are cellulose and polyester materials containing terrilytin or trypsin and 2.5% PEO with MW of 6 kDa or trypsin and 0.5% PEO with MW of 1.5 kDa. The fibre materials containing immobilized terrilytin with polyethylene oxide are resistant to radiation sterilization. The activity increases by 2-4 times in comparison to the initial materials in storage of sterilized samples at room temperature for 2 years. © 2010 Springer Science+Business Media, Inc.
