Title:
METHOD FOR CONTROLLING DECOMPOSITION OF BIODEGRADABLE POLYMERS
Document Type and Number:
WIPO Patent Application WO/2013/180124
Kind Code:
A1
Abstract:
The present invention addresses the problem of developing a technology for enabling the decomposition starting time and decomposition speed of biodegradable polymers to be controlled. This biodegradable polymer composition contains a biodegradable polymer, and spores of spore-forming bacteria having the ability to decompose the biodegradable polymer.
