Download or read book Polyhydroxyalkanoates Biopolymers written by Geeta Gahlawat and published by Springer Nature. This book was released on 2019-11-02 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on both production and extraction aspects of Polyhydroxyalkanoates (PHAs) for their commercialization purpose. PHAs have broad range of applications in packaging, food, agriculture and pharmaceutical industries. Until now literature reports have discussed either production strategies or extraction protocols. But for commercialization purpose both issues need to be addressed. This book highlights other copolymers of PHAs which have much better physico-mechanical properties such as elasticity and strength than polyhydroxybutyrate (PHB). Finally efficient product recovery protocols and process optimization strategies including renewable substrates, high cell density cultivations, genetic engineering and mathematical modeling are discussed in detail in order to outline the progress made so far in the area of economic biopolymer production. The primary audience will be scholars, researchers and professors working in colleges, universities, research institutes and government organizations.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Monomers Polymers and Composites from Renewable Resources written by Mohamed Naceur Belgacem and published by Elsevier. This book was released on 2011-10-10 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: The progressive dwindling of fossil resources, coupled with the drastic increase in oil prices, have sparked a feverish activity in search of alternatives based on renewable resources for the production of energy. Given the predominance of petroleum- and carbon-based chemistry for the manufacture of organic chemical commodities, a similar preoccupation has recently generated numerous initiatives aimed at replacing these fossil sources with renewable counterparts. In particular, major efforts are being conducted in the field of polymer science and technology to prepare macromolecular materials based on renewable resources. The concept of the bio-refinery, viz. the rational exploitation of the vegetable biomass in terms of the separation of its components and their utilisation as such, or after suitable chemical modifications, is thus gaining momentum and considerable financial backing from both the public and private sectors. This collection of chapters, each one written by internationally recognised experts in the corresponding field, covers in a comprehensive fashion all the major aspects related to the synthesis, characterization and properties of macromolecular materials prepared using renewable resources as such, or after appropriate modifications. Thus, monomers such as terpenes and furans, oligomers like rosin and tannins, and polymers ranging from cellulose to proteins and including macromolecules synthesized by microbes, are discussed with the purpose of showing the extraordinary variety of materials that can be prepared from their intelligent exploitation. Particular emphasis has been placed on recent advances and imminent perspectives, given the incessantly growing interest that this area is experiencing in both the scientific and technological realms. - Discusses bio-refining with explicit application to materials - Replete with examples of applications of the concept of sustainable development - Presents an impressive variety of novel macromolecular materials
