Microbbiological degradation of polyhydroxyalkanoates in model soil environments

The degradation of polyhydroxyalkanoates (PHA) with different chemical composition in model soil environments is studied in the article. It is shown that less crystalline co-polymer samples are destroyed faster than homopolymer ones. It is determined that the specific microbial complex is formed on PHA-surfaces and initial PHA-degrading microorganisms are identified such as: bacteria Bacillus, Mycobacterium, Streptomyces, Pseudomonas and micromycetes Penicillium, Acremonium and Trichoderma.
