Engineering bacteria for enhanced polyhydroxyalkanoates (PHA) biosynthesis
Polyhydroxyalkanoates (PHA) have been produced by some bacteria as bioplastics for many years. Yet their commercialization is still on the way. A few issues are related to the difficulty of PHA commercialization: namely, high cost and instabilities on molecular weights (Mw) and structures, thus instability on thermo-mechanical properties. The high cost is the result of complicated bioprocessing...
متن کاملProduction of Polyhydroxyalkanoates, a bacterial biodegradable polymer
There has been considerable interest in the development and production of biodegradable polymer to solve the current problem of pollution caused by the continuous use of synthetic polymer of petroleum origin. Polyhydroxyalkanoates (PHAs) are known to be accumulated as intracellular inclusion in some bacteria. The materials properties exhibited by PHAs, ranging from stiff, brittle to rubber-like...
متن کاملPolyhydroxyalkanoates production from waste biomass
Polyhydroxyalkanoates (PHAs) is a group of biopolymers that are extensively researched for such purpose due to the biocompatibility with mammal tissue and similar properties with conventional plastic. However, commercialization of PHA is impended by its high total production cost, which half of it are from the cost of pure carbon source feedstock. Thus, cheap and sustainable feedstocks are pref...
متن کامل[Microbial cell factories for production of polyhydroxyalkanoates].
Polyhydroxyalkanoates (PHA) are diverse polyesters synthesized by a variety of bacteria as intracellular carbon and energy storage compounds. As bio-renewable and biodegradable materials with diverse properties, PHA have drawn industrial attentions for their potential applications in many fields. This review focuses on recent strain developments for PHA production via cofactor engineering and m...
متن کاملIsolation and Characterization of a Bacterial Isolate for Polyhydroxyalkanoates Production
Microorganism accumulating polyhydroxyalkanoates (PHA) in its cytosol was isolated from water obtained from InCheon area. This strain was determined to be Bacillus species that was examined by 16S rDNA sequences and phylogenetic tree analysis. The bacteria accumulated up to 20.6% of PHA within 48 hours at 37 o C in the presence of 2.0% glucose substrate under aerobic condition. The present work...
