The newest installment in this superb series presents descriptions of the latest DNA recombinants molecule technology. The text combines reports on basic research in genetics with discussions of specific new industrial applications (as well as refinements of older ones) that are likely to prove highly profitable in the years to come.
Propionic acid is an important intermediate produced during anaerobic degradation of biowaste and a precursor of a large amount of methane. Its accumulation during biomethanation is however a common problem resulting in stagnation phases in biogas production. During this study, the deeper insight into the process of propionic acid degradation was intended by using modern analytical chemistry, standard microbiological approach and molecular biology for describing and explaining the problem.
This volume covers topics on humanitarian engineering education of the Lenox Institute of Water Technology and recent advances in potable water and wastewater flotation processes. The specific advancements covered include: chemical coagulation and precipitation enhancements, first wave of flotation advancement for potable water treatment, second wave of flotation technology advancement for wastewater treatment, innovative circular gravity flotation, fiber detection, fiber separation, independent physicochemical wastewater treatment systems, primary flotation clarification, secondary flotation clarification, tertiary treatment, activated sludge and flotation wastewater treatment, cold weather wastewater conditions, operation and performance of the AquaDAF process system, operation and performance of the Clari-DAF process system, water purification, spectrophotometric determination of dissolved proteins, biological and physicochemical sequencing batch reactors, and sedimentation and flotation comparisons. The book will be of value to advanced undergraduate and graduate students, to designers of flotation systems, and to scientists and researchers.
Activated Sludge - 100 Years and Counting covers the current status of all aspects of the activated sludge process and looks forward to its further development in the future. It celebrates 100 years of the Activated Sludge process, from the time that the early developers presented the seminal works that led to its eventual worldwide adoption. The book assembles contributions from renowned world leaders in activated sludge research, development, technology and application. The objective of the book is to summarise the knowledge of all aspects of the activated sludge process and to present and discuss anticipated future developments. The book comprises invited papers that were delivered at the conference "Activated Sludge...100 Years and Counting!", held in Essen, Germany, June 12th to 14th, 2014. Activated Sludge - 100 Years and Counting is of interest to researchers, engineers, designers, operations specialists, and governmental agencies from a wide range of disciplines associated with all aspects of the activated sludge process. Authors: David Jenkins, University of California at Berkeley, USA, Jiri Wanner, Institute of Chemical Technology, Prague, Czech Republic.
The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unreal- tic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to aba...
Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.
A great deal of research has been focused on the isolation, characterization, and regulation of expression of pathogenesis-related proteins since the discovery that several of the PR-proteins had antimicrobial or insecticidal activity and can delay the progression of diseases caused by several pathogens belonging to diverse genera. This is an excit
Anaerobic digestion of the organic fraction of municipal solid waste as such or together with food waste, press water or patatoes sludge was investigated to equilibrate methane production within a day or over the weekend, when no OFMSW was available. A stable co-digestion process could be achieved with COD degradation between 60 and 80 %. The max. organic loading rates were 28 kg COD/L, d. For stable methane production the OLR during Co-digestion should not excede 22,5 kg/L,
In this volume the relevance of fungi for agriculture is discussed in four sections. The first one 'Food and Fodder Production' concerns the application and potential of mushrooms, straw enrichment, and food or crop spoilage. The next section 'Mycotoxins and Detoxification' deals with the biosynthesis of mycotoxins and the use of fungi in organopollutant degradation. A large section entitled 'Disease Control, Diagnostic, and Management' covers various aspects of biological control (fungi, insects, and weeds), diagnostics with emphasis on the example of Magnaporthe grisea, and disease management with focus on the important fungal pathogens Phoma, Fusarium, rusts and powdery mildew. The last section 'Update on Host-Parasite Interactions' discusses signal transduction, avirulence determinants, phytotoxins, cell wall degradation, and the coevolution of pathogenic fungi and grass hosts.
