The biodegradation of polyhydroxyalkanoates (PHAs) by microbial and
enzymatic methods attracts much attention since the ranges of potential applications of
PHAs grow wider. However, there are limited reports on the isolation of poly(3-
hydroxybutyrate) P(3HB)-degrading bacteria and detail study on the production of
P(3HB) depolymerase enzyme by microorganisms from Malaysian environments.
