This book was released on 2010 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polybeta-hydroxybutyrate (PHB) is a biodegradable close substitute for non-biodegradable synthetic plastic. Its production by 79 local bacteria obtained from dumpsite soils and sewage sludge was explored in the study, initially by clear zone formation indicative of both synthesis and degradation in PHB medium, staining of cultured cells with Sudan Black B and, finally, by the chemical method of Law & Slepecky (1961) followed by UV-Vis spectrophotometry at 235nm of yields from a chemically defined medium (FBM) used in batch fermentation. focus wwas on Burkholder cepacia (I-79), B pseudomallei (I-50), Stenotrophomonas maltophilia (I-69), Pseudomonas putida (I-68) and Synthrophomonas wolfei (I-78). Production by these isolates with 20g glucose and 0-4g (NH4)2HPO4 registered highest with no significant differences with sucrose and glucose at 30g and SCM and SWL at 35g. In fermentation runs at 30 degrees with continuous aeration (200rpm), the same amount of (NH4)2HPO4 and 20g glucose, sucrose, sugarcane molasses (SCM) and sulphite waste liquor (SWL) as C sources, yields were higher at pH 7 than at pH 5. Yields were consistently low on the 24th hr and peaked on the 48th hour with the N source at 2g for I-69 (S. maltophilia) and 4g for the other four isolates. Production by all five isolates also differed with the C sources, generally in decreasing order from sucrose, to glucos, SCM and SWL. Moreover prolonged fermentation up to 72 hr resulted in decreased yields by all isolates irrespective of C source and amount of N source. Similar changes in PHB production with fermentation time by the isolates other than I-69 were obtained in tests with increased levels of C sources (25-40g) and (NH4)2HPO4 (5-7g); yields were highest with no significant differences with sucrose and glucose at 30g and SCM and SWL at 35g. Dry biomass of the isolatews correlated in general with PHB yields, which, however, likewise did not differ significantly in further tests with these amounts of the C sources in combination with (NH4)Dry biomass of the isolates correlated in general with PHB yields, which, however, likewise did not differ significantly in further tests with these amounts of the C sources in combination with (NH4)2HPO4, (NH4)2MO4 or (NH2)2CO at 0-4g for I-69 and 4-7g for the other four bacterial isolates. Overall, I-79 (B. cepacia), a wild-type strain isolated from sewage sludge of Central Fermentation Corporation in Sulipan, Apalit, Pampanga, gave as much as 71% PHB yield equivalent to 4.25g per liter of FBM with 4g (NH2)2CO and 35g SCM at a minimal total cost of PhP 0.22 per 1% PHB.
Book Synopsis Mixed Culture PHA Production from Olive Oil Mill Pomace by : James Lincoln Waller
Download or read book Mixed Culture PHA Production from Olive Oil Mill Pomace written by James Lincoln Waller and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: PHA was produced in bench-scale SBRs fed olive pomace fermentate containing a mixed microbial consortium. The system consisted of an initial anaerobic fermentation to produce soluble carbon compounds, mainly organic acids, in a sequencing batch fermentor (SBF). SBF effluent was centrifuged, removing solids, and fed into a sequencing batch reactor (SBR) where intracellular PHA was produced. Buffer pre-treatment of diluted olive pomace increased organic acid production 75% in SBF fermentate over no pre-treatment. A 4 day HRT and pomace concentration of 75 g/L with buffer pre-treatment maximized pomace conversion yield at 0.0147 g organic acid/g pomace. Anoxic/oxic cycling in SBRs was not required and SBR #14 displayed the highest %PHA and volumetric productivity at 39% and 0.042 g PHA/L-day respectively in SBR #14 under fully aerobic conditions. SBR #3 exhibited the highest PHA conversion yield at 0.3625 g PHA/L fermentate.

Book Synopsis Plastics from Bacteria by : George Guo-Qiang Chen
Download or read book Plastics from Bacteria written by George Guo-Qiang Chen and published by Springer Science & Business Media. This book was released on 2009-12-02 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the possibility that petroleum supplies will be exhausted in the next decades to come, more and more attention has been paid to the production of bacterial pl- tics including polyhydroxyalkanoates (PHA), polylactic acid (PLA), poly(butylene succinate) (PBS), biopolyethylene (PE), poly(trimethylene terephthalate) (PTT), and poly(p-phenylene) (PPP). These are well-studied polymers containing at least one monomer synthesized via bacterial transformation. Among them, PHA, PLA and PBS are well known for their biodegradability, whereas PE, PTT and PPP are probably less biodegradable or are less studied in terms of their biodegradability. Over the past years, their properties and appli- tions have been studied in detail and products have been developed. Physical and chemical modifications to reduce their cost or to improve their properties have been conducted. PHA is the only biopolyester family completely synthesized by biological means. They have been investigated by microbiologists, molecular biologists, b- chemists, chemical engineers, chemists, polymer experts, and medical researchers for many years. PHA applications as bioplastics, fine chemicals, implant biomate- als, medicines, and biofuels have been developed. Companies have been est- lished for or involved in PHA related R&D as well as large scale production. It has become clear that PHA and its related technologies form an industrial value chain in fermentation, materials, feeds, and energy to medical fields.
Book Synopsis Post Treatments of Anaerobically Treated Effluents by : Vinay Kumar Tyagi
Download or read book Post Treatments of Anaerobically Treated Effluents written by Vinay Kumar Tyagi and published by IWA Publishing. This book was released on 2019-06-15 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anaerobic process is considered to be a sustainable technology for organic waste treatment mainly due to its lower energy consumption and production of residual solids coupled with the prospect of energy recovery from the biogas generated. However, the anaerobic process cannot be seen as providing the ‘complete’ solution as its treated effluents would typically not meet the desired discharge limits in terms of residual carbon, nutrients and pathogens. This has given impetus to subsequent post treatment in order to meet the environmental legislations and protect the receiving water bodies and environment. This book discusses anaerobic treatment from the perspective of organic wastes and wastewaters (municipal and industrial) followed by various post-treatment options for anaerobic effluent polishing and resource recovery. Coverage will also be from the perspective of future trends and thoughts on anaerobic technologies being able to support meeting the increasingly stringent disposal standards. The resource recovery angle is particularly interesting as this can arguably help achieve the circular economy. It is intended the information can be used to identify appropriate solutions for anaerobic effluent treatment and possible alternative approaches to the commonly applied post-treatment techniques. The succeeding discussion is intended to lead on to identification of opportunities for further research and development. This book can be used as a standard reference book and textbook in universities for Master and Doctoral students. The academic community relevant to the subject, namely faculty, researchers, scientists, and practicing engineers, will find the book both informative and as a useful source of successful case studies.

Book Synopsis The Microbiology of Activated Sludge by : Robert J. Seviour
Download or read book The Microbiology of Activated Sludge written by Robert J. Seviour and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been a long time in preparation. Initially it grew out of our frustrating attempts over the past ten years to identify the filamentous bacteria seen in large numbers in most activated sludge plants, and the realization that we know very little about them and the other microbial populations in these systems. Unfortunately this book does not provide many answers to the problems these filamentous bacteria can cause, but we hope it might encourage microbiologists and engineers to communi cate more with each other and to spend some time trying to understand the tax onomy, ecology and physiology of activated sludge microbes. It is now very timely, for example, to try to provide these filamentous bacteria with proper taxonomically valid names and to determine their correct place in bacterial classifications. This book is not meant to compete directly with the books by Gray (1989, 1990) nor the excellent manual published by Jenkins and coworkers (1993b), which has been invaluable to us and others trying to identify filamentous bacteria. Wanner's book (1994a) also provides an excellent account of the problems of bulking and foaming caused by filamentous bacteria. These publications and others by Eikelboom's group have made an enormous contribution to the study of filamentous bacteria, and will con tinue to do so.

Available in PDF, EPUB and Kindle. Book excerpt: The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.
