The results showed partial degradation of the copolymer submitted to physic treatments and colonization by B. subtilis. The best results of degradation were associated with protease, amylase and esterase on surface of PET particles submitted to 50°C of temperature, during 60 days. However, the esterase activity simulating biodegradation of PET by B. subtilis, and suggest residual lost of weight, and the products showed low toxicity when compared with the PET particles without treatments.
