Polyhydroxyalkanoate Biodegradation

Depending on the composition, bacterial bioplastics degrade in about 1-6 months.  When exposed to enzymes or to the natural microorganisms in the environment, these natural polymers could undergo enzymatic hydrolysis or chemical hydrolysis yielding carbon dioxide and water.  The major factors that influence the degradation includes the chain composition, sample structure, thickness, crystallinity, morphology, temperature and pH.
