Screening of different microorganisms for their biodegradation capacity regarding polyester-based thermoplastic polyurethanes

Detalhes bibliográficos
Resumo:	and bio-based solutions in shoe manufacturing, including the use of biodegradable materials. As a first step towards the proposal of such solutions, in this work different microorganisms were screened for their intrinsic capacity to degrade a base TPU. The biodegradability was tested using the agar plate method against different bacteria, fungi and a consortium of both. The most promising results, corresponding to higher weight-loss percentages of the TPU sample, were obtained using the consortium of Pseudomonas aeruginosa and Aspergillus niger. These best conditions were thereafter applied to TPU samples compounded with biobased additives.
