This book was released on 1989 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies have been carried out in order to optimize growth and culture conditions for the intracellular formation of poly Beta-hydroxyalkanoates) (PHA) in the phototrophic, purple, non-sulphur bacterium Rhodospirillum rubrum. Its potential to produce novel copolymers was investigated. Recently, it has become of industrial interest to evaluate these polyesters as potentially biodegradable plastics for a wide range of possible applications. On an industrial scale, the use of photosynthetic bacteria could harness sunlight as an energy source for the production of these materials. R. rubrum was grown anaerobically in the light on different linear and content of up to 45% of cellular dry weight was detected. When R. rubrum was grown on different concentrations of various n-alkanoic acids, intracellular PHA production was detected on all acids used. In most of the cases, the storage polymer contained Beta-hydroxybutyrate (HB) and Beta-hydroxyvalerate (HV) monomer units. Grown on n-alkanoic acid as the carbon source, a polyester which contained HB, HV, HC, and Beta-hydroxyheptanoate was formed. These copolyesters represent a novel class of biodegradable thermoplastics. Reprints. (AW).

Download or read book Microbial Biopolyester Production Performance and Processing Microbiology Feedstocks and Metabolism written by Martin Koller and published by Bentham Science Publishers. This book was released on 2016-09-30 with total page 515 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: 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.)
