Polyhydroxyalkanoate(s) (PHA) have gained rapid interest worldwide. The structural diversity of hydroxyalkanoates has resulted in materials with a wide range of physical and thermal characteristics. In addition, the variety of characteristics are significantly impacted by every aspect of upstream processing, as well as recovery during downstream processing. The diversity and versatility of PHA have opened up various opportunities for exploitation as many possibilities are yet to be discovered and evaluated in various applications. [Pg.141]

Dr. Jose M. Luengo found that unusual polyhydroxyalkanoates (UnPHAs) constitute a particular group of polyoxo(thio)esters belonging to the PHA family, which contain uncommon monomers. He classifies the UnPHAs into four classes and discusses some of their characteristics and biotechnological applications. [Pg.457]

The aliphatic biopolyesters are mainly polyhydroxyalkanoates (PHAs) like the poly-P-hydroxybutyrate (PHB), polyhydroxyvalerate (PHV), and polyhydroxyhexanoate (PHH). It not only resembles conventional petrochemical mass plastics (like PE or PP) in its characteristics, but it can also be processed easily on standard equipment that already exists for the production of conventional plastics. [Pg.48]

An indepth description of polyhydroxyalkanoates (PHA) is given in Chapter 7 of this book so, in this chapter only the main characteristics of this class of aliphatic polyesters will be disclosed. [Pg.323]

A homopolymer of (R)-3-hydroxybutyrate (PHB) is the most common type of PHA that bacteria accumulate in nature and has been studied and characterized extensively by many researchers. Poly (P-hydroxybutyrate) (PHB) has a number of interesting characteristics and can be used in various ways similar to maity conventional synthetic plastics now in use. The properties of polyhydroxyalkanoates viz. PHB, PHV and comparison with synthetic polymer polypropylene (PP) have been described by Sasikala and Ramana (1996). [Pg.216]
