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.
