    Polyhydroxyalkanoates (PHAs) are polyesters of hydroxyalkanoates   synthesized by numerous bacteria as an intracellular carbon and   energy storage compounds. PHAs have attracted much attention as   substitute for non-degradable plastics derived from   petrochemicals because of their similar material properties to   conventional plastics along with complete biodegradability under   natural environmental conditions upon disposal. In this chapter,   extracellular as well as intracellular biodegradation of PHAs by   diverse bacteria and fungi is reviewed. Several topics namely,   factors affecting biodegradation of plastics, methods used for   isolation of PHA degrading organisms, biodegradation of PHAs,   biochemical properties of several PHA depolymerases produced by   variety of organisms are discussed in detail in this chapter. It   also includes mechanisms of action of intracellular as well as   extracellular PHB depolymerases with major emphasis on mode of   action of extracellular PHB depolymerase from Pseudomonas   lemoignei   and Penicillium funiculosum   as well as intracellular PHB depolymerase ofCupriavidus   necator.
