Production of polyhydroxyalkanoates (PHAs) has been investigated for more than eighty years but recently a number of factors including increase in the price of crude oil and public awareness of the environmental issues have become a notable driving force for extended research on biopolymers. The versatility of PHAs has made them good candidates for the study of their potential in a variety of areas from biomedical/medical fields to food, packaging, textile and household material. While production costs are still a drawback to wider usage of these biopolymers, their application as low volume high cost items is becoming a reality. The future trend is to focus on the development of more efficient and economical processes for PHA production, isolation, purification and improvement of PHA material properties.
