Abstract

The review reports studies of PHA biodegradation behavior in natural freshwater and marine environments. The factors determining polymer degradation rates in water basin include the temperature and the mineral component of the water, the structure of the aquatic ecosystem and bacterioplankton composition. Anaerobic degradation occurs at slower rates as compared with aerobic process. One of the factors limiting PHA degradation rates is deficiency of dissolved mineral phosphorus, which hinders the development of microbial components of the ecosystem. Differences in biodegradation patterns of PHA specimens are accounted for by different structures and surface areas of specimens, which influence the adhesion of microorganisms. Bacteria are main PHA destructors in water ecosystems as opposed to soil environments where micromycetes are most significant degraders
