Microbial Polyesters

• Gebundenes Buch

Produktbeschreibung

This is the first book to present a topical overview of the research and development of microbial polyesters.

Comprehensive and amply illustrated, it covers the
_ biosynthesis
_ structure
_ properties
_ applications
of these biodegradable and biocompatible thermoplastics.

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.
