Bacterial degradation of modified polyuretane foams: comparison of single and mixed culture

Original language description

Polyurethanes (PUR) present widespread group of polymers which are involved in many aspects of modern life. They found use in medical, automotive and industrial fields. Live of modern industrial society is connected with accumulation of bad-degradable polymer waste including PUR materials. This situation leads to necessity to solve problems with negative effects of polymer solid waste on environment. In agreement with recent trends to avoid the accumulation of environmental pollution new modified PUR foams were synthesized. In this work, biodegradability of relatively resistant PUR foams was enhanced using biopolymer components (acetyl-, hydroxyethyl- and carboxymethyl cellulose, acetylated starch, glutein) as modifying agents. To biodegradation of modified PUR mixed aerobic thermophillic bacterial culture Thermophillus sp. and single culture of common soil bacteria Artrobacter globiformis were tested. Dynamic cultivation of microorganisms was performed in the minimal media with PUR. G
