Rapid and simple colorimetric assay for detecting the enzymatic degradation of biodegradable plastic films

We developed a rapid and simple method for evaluating the degradation of solid biodegradable plastics (BPs). Dye-containing BP films were used as substrates and the release of dye caused by the degradation of BPs was confirmed by a color change in the enzyme solution after a reaction time of 24 h.
