Polyhydroxyalkanoate (PHA) is a group of natural biopolymers synthesised by a wide variety of microbial genera. It is a biodegradable and biocompatible thermoplastic consisting of a repeated chain of various hydroxyalkanoate monomers.PHA is envisioned to be one of the most prospective and futuristic materials which is beneficial to mankind and to the world. In current world trends which concerns at the sustainable development from renewable and eco-friendly resources, PHA has garnered a growing attention as an alternative to petroleum based plastics.The book comes with two main objectives. In this book, major pipelines in processing this beneficial biopolymer were first reviewed from upstream to the downstream. The upstream processing includes the isolation of PHA producers, biosynthesis of PHA, genetic modification of PHA producers and optimisation of PHA production; meanwhile the downstream processing covers the PHA recovery and purification, degradation, quantification, characterisation, as well as the application of PHA. Readers will be exposed to the introductory information, along with some necessary concepts behind each subject.The second objective of this book is to provide readers with the recent advances on each PHA processing field. Being updated with the recent findings, this will provide an insight to readers on how the research trends for each subject are evolving from time to time. These updates will become useful case studies and quick references to readers from various areas, either from academia or industry.

Global plastic production is estimated to be over 300Mt annually. Most conventional plastics are predominantly produced from fossil fuels and are highly resistant to biodegradation, and only a small share of about 20% of spent plastics is believed to be recycled, which is a cause for environmental concern. Biodegradable plastics would solve this concern as they are a sustainable alternative, yet these do not even cover 5% of the global plastic market. Microbial polyhydroxyalkanoates (PHAs) are a versatile group of polyesters produced by nature as prokaryotic storage materials. PHAs can be produced through sustainable bioprocess engineering and have displayed remarkable flexibility in their physical and chemical properties. PHAs are the subject of several scientific papers and numerous PHA patents have also been filed, generating significant interest in the plastic production industry. To develop overall sustainable and efficient production processes, all bioprocess steps need to be thoroughly understood and accounted for. These processes start with the selection of suitable inexpensive raw materials (microbes and enzymes), optimizing the process engineering and process regime, and conclude with the enhancement of product recovery in terms of time, energy, and material input. Microbial Biopolyester Production, Performance and Processing: Microbiology, Feedstocks, and Metabolism encompasses eight chapters that cover aspects of the microbiology and biotechnology of producing biodegradable plastics. The contents focus on the selection of powerful archaeal and eubacterial production strains, genetic engineering as a tool for optimized PHA production and inexpensive carbon sources for microbial cultures. The volume is a useful resource for bioprocess engineers, microbiologists, biotechnologists and chemical engineers interested in the basics of biodegradable plastic production. Recent Advances in Biotechnology is a book series comprising of peer-reviewed reference works and monographs that compile the latest developments in the field of biotechnology. Each volume has a thematic focus and features topical reviews written by experts. The series will highlight multidisciplinary perspectives to interested readers (biotechnologists, microbiologists, bioprocess engineers, agronomists, medical professionals, sustainability researchers etc.)

This first volume of the Metabolic Pathway Engineering Handbook provides an overview of metabolic pathway engineering with a look towards the future. It discusses cellular metabolism, including transport processes inside the cell and energy generating reactions, as well as rare metabolic conversions. This volume also explores balances and reaction models, the regulation of metabolic pathways, and genome scale and multiscale modeling tools. It also covers developing appropriate hosts for metabolic engineering including the use of Escherichia coli, yeast, Bacillus Subtilis, Streptomyces, filamentous fungi, and mammalian cells using cell culture. Christine Smolke, who recently developed a novel way to churn out large quantities of drugs from genetically modified brewer’s yeast, is regarded as one of the most brilliant new minds in biomedical engineering. In this handbook, she brings together pioneering scientists from dozens of disciplines to provide a complete record of accomplishment in metabolic pathway engineering. With a wealth of cutting edge research and analysis, this work also serves as an invaluable resource for those seeking to add their own contributions. Organized by topic, this 3000 page reference is available as two volumes that can be purchased individually or as a set. For information on the complete handbook visit Cat No. 3923

The best of the "Biopolymers" series. Since only a small number of individuals can afford to buy the entire Biopolymers series, or would simply prefer a broader overview, this handbook contains the very best of biotechnology, with articles taken directly from Alexander Steinbüchel´s successful series. As such, these two volumes cover the entire range of biopolymers and not just one chemical class, with the focus on the biotechnological systems and processes under development for a cost effective production, isolation and modification of biopolymers. Furthermore it covers the fundamentals of their chemical and physical properties, their occurrence, metabolism, biosynthesis and biodegradation as well as their industrial applications as renewable resources, novel materials and technical applications. With its contributions similarly structured for easy data comparison and an extensive table of patents, this is an ideal reference for medium sized laboratories and libraries.
