| Abstract: | Polyhydroxyalkanoates(PHAs) that are the polymers of hydroxyalkanoates that accumulate as carbon and energy storage material in various microorganisms are attracting considerable attention as completely biodegradable thermoplastics with favourable mechanical properties and environmental effect.The use of activated sludge and cheap substrates can reduce the production cost of PHAs.Recent development of PHAs studies including process and influence of PHAs synthesis by activated sludge and strategy on improving the yield of PHAs was reviewed. |
