This is the first book to present a topical overview of the research and development of microbial polyesters.<br> <br> Comprehensive and amply illustrated, it covers the<br> * biosynthesis<br> * structure<br> * properties<br> * applications<br> of these biodegradable and biocompatible thermoplastics. <br> <br> The book provides the reader with the necessary background to understand the nature and mechanism of biological polymerization. It unites aspects from both the biological and polymer sciences and is a typical modern example of the analysis of biological macromolecules.
