Polyhydroxyalkanoates(PHAs) are a type of polyester synthesized by microorganisms in the form of inclusion body. The polyesters are developing as the alternatives of traditional petroleum-based plastics because of its biodegradability and biocompatibility. The kind of mediums result in the difference of biopolymers in types
characteristics and cost. The carbon sources are the main nutrients for biosynthesis. However
expensive carbon sources increase the cost of PHA biosynthesis
which limits large-scale production and application in PHA. Therefore
it is very significant to explore the proper and inexpensive carbon sources and the utilization ways of inexpensive carbon sources. The types of microorganisms are introduced. The inexpensive carbon sources
the utilization ways of inexpensive carbon sources and properties and applications of PHA are reviewed. The screening and utilization of inexpensive carbon sources are expected to cut down the cost of PHA biosynthesis remarkably and enhance economics and competitiveness in PHA.
