摘要: Biodegradation of residual polyurethane by means Aspergillus niger was evaluated. Respirometric tests were performed using an OXITOP equipment, which showed a 98% consumed oxygen in 200 hours lapse. done aerated accumulation reactor, at 40% humidity and 25 oC temperature during 45 days. Spectroscopy IR analysis 610 cm -1 band, corresponds to aromatic rings that released when the amide II IV links broken. Sweep Electronic Microscopy (SEM) changes surface.
