It shows that PHA degradation in tropical soils is influenced by polymer chemical composition, specimen shape, and microbial characteristics. The homopolymer of 3-hydroxybutyric acid is degraded at higher rates than the copolymer of 3-hydroxybutyric and 3-hydroxyvaleric acids. The average rates of mass loss were 0.04-0.33% per day for films and 0.02-0.18% for compact pellets. PHA degradation was accompanied by a decrease in the polymer molecular mass and, usually, an increase in the degree of crystallinity, suggesting preferential degradation of the amorphous phase. Under the study conditions, representatives of the bacterial genera Burkholderia, Bacillus, Cupriavidus, Mycobacterium, and Nocardiopsis and such micromycetes as Acremonium, Gongronella, Paecilomyces, and Penicillium, Trichoderma have been identified as major PHA degraders.
