Download or read book Microbial Biopolyester Production Performance and Processing Bioengineering Characterization and Sustainability written by Martin Koller and published by Bentham Science Publishers. This book was released on 2016-12-06 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Current Advances in Biopolymer Processing and Characterization written by Martin Koller and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents current R&D activities to unravel the physico-chemical properties of diverse biopolymers, and their processing towards functionalised, high-performance bio-products with defined applications. The importance of this research becomes obvious by considering the annual plastic production of about 330 Mt, the lion's share thereof based on the conversion of fossil feedstocks that is highly recalcitrant against biodegradation. Alternative environmentally degradable plastics cover not even 5% of today's plastic market. Such biopolymers encompass various macromolecules of biological origin with diverse monomeric composition, and manifold physico-chemical properties. This structural diversity makes them potential candidates to produce bulk materials, e.g., for packaging purposes, smart functionalised materials in special niches like the biomedical field. Consequently, we witness an increasing trend towards new natural polymers to replace well-established products like plastics. After decades of global R&D developments in this field, and numerous body blows on the way to the anticipated market breakthrough of biopolymers, it is generally recognised that the success of such new materials needs progress in both material performance and production prices. The book Current Advances in Biopolymer Processing & Characterisation is dedicated to the current state-of-the-art of production, modification, characterisation, and processing of two major biopolymer groups: Firstly, polysaccharides, nature's most abundant raw materials, are represented by specialised contributions on biomedical applications of starch and its follow-up products. Polysaccharides were also studied for the examples of functionalised thermoplastic starch, molecular and hydrocolloidal characteristics of xanthan in aqueous environments, and by the design of functionalised xylan-based bio-materials. Secondly, the second series of contributions encompasses diverse biopolyesters. Advanced methods to improve the properties of PLA, fine-tune PLA properties by triggering PLA's crystallisation rate during melt processing, and the strongly emerging field of 3D-printing of PLA, PCL, and microbial PHA are described. Finally, the authors familiarise the reader with the application of mixed microbial cultures to produce PHA heteropolyesters with different thermo-mechanical properties in dependence on cultivation strategy and the microbial species composition. This compilation of new biomaterials with surprising functions and performance, based on these natural polymers will address scientists active in biopolymers production, functionalisation, characterisation, and processing towards bio-technomers. The book is also dedicated to undergraduate students of polymer chemistry and polymer processing, and to representatives of the polymer industry who are interested in developing innovative, sustainable and smart polymeric products. Activities motivated by reading this book shall boost the impatiently desired market penetration of biopolymers and their follow-up products. Such materials definitely display a socioeconomic impact by addressing prevailing ecological concerns such as depleting fossil resources, growing piles of plastic waste, and increasing global warming. The contributions to this book illustrate that bio-inspired remedies for prevalent ecological problems are already available, developed by experts in polymer sciences and engineering, or that these solutions are at least in the status of development.

Available in PDF, EPUB and Kindle. Book excerpt: Polyhydroxyalkanoates: Biosynthesis, Chemical Structures and Applications opens with an exposé on employing extremophiles as polyhydroxyalkanoate (PHA) producers. The authors suggest that extremophiles may be easily subjected to a long-term continuous cultivation processes, which considerably enhances overall productivity while reducing the energy demand in biopolymer production. Conversely, a range of challenges remain, including improving the metabolic capability of extremophiles, recycling of fermentation broth, various process engineering aspects, and adaptation of bioreactor materials and process controlling devices to conditions shortening their life span. Following this, the enzymes, regulators and genes involved in PHA biosynthesis are analyzed for their potential as an alternative to synthetic polymers. They are synthesized as intracellular carbon and energy storage compounds from over 300 species in the presence of excess carbon and under oxygen, nitrogen or phosphorus limitation, or after pH shifts. This collection goes on to suggest PHA as a promising alternative for petrochemical compounds. The challenges of increasing economic feasibility in the global market, minimizing costs, and improving the polymer yield are reviewed. Additionally, recent research on structural variations of PHAs has been centered on the design, biosynthesis, and properties of biodegradable and biocompatible materials, which can be used for bioengineering. This collection also includes a focus on the roles of polyhydroxyesters and PHAs in the construction of tissue engineering scaffolds, which are used in bone, cartilage, ligament, skin, vascular tissues, neural tissues and skeletal muscles. Their exceptional properties, such as high surface-to-volume ratio, high porosity with very small pore size, and biodegradation have made them gain a lot of attention in this field. The biomedical applications of PHAs are explored, including in-vivo implants, tissue engineering, anticancer agents, drug delivery, biocontrol agents and memory enhancers, as their low acidity allows for minimal risk in usage. In order to enhance its applicability in various fields, the blends and nanocomposites of PHAs are studied and their potential challenges, applications and opportunities are addressed. After which, the industrial and agricultural applications are described, with specific focus on potential applications of PHAs in packaging. Other applications include moulded goods, paper coatings, non-woven fabrics, adhesives, films and performance additives. Recent advances in this area, by means of peer-reviewed literature and patents, are introduced and discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, we are witnessing highly dynamic research activities related to the intriguing field of biodegradable materials with plastic-like properties. These activities are stimulated by the strengthened public awareness of prevailing ecological issues connected to growing piles of plastic waste and increasing greenhouse gas emissions; this goes hand-in-hand with the ongoing depletion of fossil feedstocks, which are traditionally used to produce full carbon backbone polymers. Polyhydroxyalkanoate (PHA) biopolyesters, a family of plastic-like materials with versatile material properties, are increasing considered to be a future-oriented solution for diminishing these concerns. PHA production is based on renewable resources and occurs in a bio-mediated fashion through the action of living organisms. If accomplished in an optimized way, PHA production and the entire PHA lifecycle are embedded into nature´s closed cycles of carbon. Sustainable and efficient PHA production requires understanding and improvement of all the individual process steps. Holistic improvement of PHA production, applicable on an industrially relevant scale, calls for, inter alia, consolidated knowledge about the enzymatic and genetic particularities of PHA-accumulating organisms, an in-depth understanding of the kinetics of the bioprocess, the selection of appropriate inexpensive fermentation feedstocks, tailoring of PHA composition at the level of its monomeric constituents, optimized biotechnological engineering, and novel strategies for PHA recovery from biomass characterized by low energy and chemical requirements. This Special Issue represents a comprehensive compilation of articles in which these individual aspects have been addressed by globally recognized experts.
