Enzymatic Self-Biodegradation of Poly( l -lactic acid) Films by Embedded Heat-Treated and Immobilized Proteinase K

QiuYuan Huang, Masatoshi Hiyama, Taizo Kabe, Satoshi Kimura et autres

Abstract Non-biodegradable microplastics have become a global problem. We propose a new enzyme-embedded biodegradable plastic that can be self-biodegraded anytime and anywhere. Proteinase K from Tritirachium album was embedded in poly(l-lactic acid) (PLLA). The PLLA solution-cast film with embedded proteinase K showed …
