Cotton fabric as a carrier to immobilize chemically modified papain
Papain (EC 3.4.22.2) has been chemically modified by pyromellitic acids. Then, the modified papain was immobilized on the activated cotton fabric by a two-step method. Fourier transform infrared spectrometry (FT-IR) and energy dispersive spectrometry (EDS) were used to characterize papain immobilization. Some parameters of both modified and native papain immobilized on cotton fabric, such as optimum pH, the reusability and storage stability, were studied and compared. The resultant papain had its optimum pH shifted from 7.0 to 9.0, and the reusability and storage stability were improved considerably compared to the immobilized native papain. This work demonstrated that the cotton fabric immobilized by modified papain has potential applications in the functional textile field.
