Polyhydroxyalkanoate (PHA) is a biodegradable polymer and produced by diverse microorganisms and have been emphasized as a potential alternative for petroleum-based plastics by virtue of their physical properties and environmentally friendly characteristics. As a result, there have been various studies on PHA production containing different monomers giving different thermal and physical properties. Among them, we have studied the production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate- co-3- hydroxyhexanoate) from different carbon sources and various strains such as Escherichia coli and Ralstonia eutropha. These kinds of approaches will be helpful to produce more economical PHAs, improve physical properties of PHAs and avoid the usage of non-biodegradable polymers in many different fields in near future. |
