Environment polyhydroxyalkanoate

The exhaustible nature of the oil reserves and the pollution that oil-based technological polymers can have on the environment has rekindled an interest in polymers of natural origin, in particular the biotechnological polymers. Until now, however, the polyhydroxyalkanoates are the only biotechnological polymers that have been developed industrially, occupying a notable position as biodegradable and biocompatible biomaterials for temporary use [1, 2].

Polyhydroxyalkanoates (PHA), a family of biopolyesters with diverse structures, are the only bioplastics completely synthesized by microorganisms. PHA can be synthesized by over 30% of soil-inhabiting bacteria (Wu et al. 2000). Many bacteria in activated sludge, in high seas, and in extreme environments are also capable of making PHA. In the last 10 years, PHA have been developed rapidly to find applications in various fields (Fig. 1) (Chen 2009a). [Pg.19]
