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: Bioengineering, Characterization, and Sustainability is a compilation of eight chapters covering bacterial polyesters, green plastics and PHAs from various angles. The contents of this volume focus on sustainable practices focus on the sustainability of processes that involve the synthesis and recycling of these meterials. The volume is a useful resource for bioprocess engineers, microbiologists, biotechnologists and chemical engineers interested in the basics of biodegradable plastic production.

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.)

Technology and Applications of Polymers Derived from Biomass explores the range of different possible routes from biomass to polymeric materials, including the value and limitations of using biomass in material applications and a comparison of petrochemical-derived polymers and bio-based polymers. The book discusses biomass sources, types, chemistry and handling concerns. It covers the manufacture of industrial chemicals from biomass and the derivation of monomers and polymers from biomass. It also details the processing and applications of biomass-derived polymers to enable materials scientists and engineers realize the potential of biomass as a sustainable source of polymers, including plastics and elastomers. The book is a one-stop-shop reference—giving students a basic understanding of the technology and how the material can be applied to industrial processes they will face in the workforce, and giving materials engineers and product designers the information they need to make more informed material selection decisions. Provides fundamental understanding of an increasingly important approach to sourcing polymeric materials Includes actionable, relevant information to enable materials engineers and product designers consider biomass-derived polymers in the products they are developing Discusses the environmental impact of biomass conversion to help readers improve the sustainability of their operations Compares petrochemical-derived polymers with bio-based polymers

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.
