Book excerpt: Das Ziel der Arbeit bestand darin, die lokalen und globalen mechanischen Beanspruchungsparameter in einem Rührkesselbioreaktor mit Hilfe der numerischen Strömungssimulation (CFD) nachzubilden und die Ergebnisse mit experimentellen Daten der Pellet-kultivierung bzgl. Fluiddynamik und Rheolgie des rekombinanten Stammes A. niger SKAn1015 zu validieren. Ausgehend von der einphasigen Strömungssimulation eines 2L-Bioreaktors werden zunächst Simultionsdaten über Strömungsgeschwindigkeit und mechanische Beanspruchung diskutiert. Aßerdem erfolgt eine Validierung der einphasigen Simulationsdaten mit der Particle Image Velocimetry. In weiteren Untersuchungen wird die Strömungssimulation auch auf nicht-newtonsche Flüssigkeiten, so wie sie bei der Kultivierung filamentöser Pilze üblicherweise auftreten, mit dem Ostwald - de Waele-Ansatz erweitert und die mechanische Beanspruchung in Abhängigkeit zu den rheologischen Prozessparametern korreliert. Die Untersuchung des Einflusses unterschiedlicher Rührergeometrien auf die Strömungsfelder und die mechanische Beanspruchung mittels CFD bildet den Abschluss, so dass die Auswahl eines geeigneten Rührers für den Kultivierungsprozess mit schesensitiven biologischen Systemen eindeutig getroffen wird. Die Arbeit validiert die numerische Strömungssimulation in einem Bioreaktor mit experimentell gnerierten biologischen und fluiddynamischen Prozessdaten und gibt praktische Hinweise darüber, wie biotechnologische Prozesse mit filamentösen Mikroorganismen hinsichtlich der Minimierung der mechanischen Beanspruchung zu betreiben sind.
Book Synopsis Production of labyrinthopeptin A1 with Actinomadura namibiensis by : Sebastian Tesche
Download or read book Production of labyrinthopeptin A1 with Actinomadura namibiensis written by Sebastian Tesche and published by Cuvillier Verlag. This book was released on 2020-12-21 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The filamentous actinomycete Actinomadura namibiensis is the only known producer of labyrinthopeptins, a class of ribosomally synthesized and posttranslationally modified peptides (RiPPs) displaying highly attractive bioactive properties. In order to increase the labyrinthopeptin A1 productivity in shaking flask cultivations of A. namibiensis, a new cultivation method called salt-enhanced cultivation was used. Compared to the unsupplemented control, labyrinthopeptin A1 productivity was enhanced the most by addition of 50 mM (NH4)2SO4, reaching a 7-fold higher yield of 325 mg L-1 within 10 cultivation days. Salt-enhanced cultivation affected growth and product formation mechanisms, cell morphology characteristics and rheological characteristics of cultivation broth. An image analysis method was developed to quantify both the macro-morphology (pellet size and shape) and the micro-morphology (hyphal network structure) of the heterogeneous filamentous biomass in detail. Productivity-related morphological parameters were in particular the size and circularity of pellets and the degree of hyphal interweaving (hyphal network spacing). It was shown that the time-dependent change in morphology linked to the rheological properties of the cultivation broth. The results presented in this work provide new insights into the cultivation aspects of A. namibiensis and illustrate the challenges on the way to a comprehensive understanding of the complex relationship between productivity, morphology and rheology in filamentous cultivations.

Book Synopsis Bioprocess Engineering Principles by : Pauline M. Doran
Download or read book Bioprocess Engineering Principles written by Pauline M. Doran and published by Elsevier. This book was released on 1995-04-03 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence and refinement of techniques in molecular biology has changed our perceptions of medicine, agriculture and environmental management. Scientific breakthroughs in gene expression, protein engineering and cell fusion are being translated by a strengthening biotechnology industry into revolutionary new products and services. Many a student has been enticed by the promise of biotechnology and the excitement of being near the cutting edge of scientific advancement. However, graduates trained in molecular biology and cell manipulation soon realise that these techniques are only part of the picture. Reaping the full benefits of biotechnology requires manufacturing capability involving the large-scale processing of biological material. Increasingly, biotechnologists are being employed by companies to work in co-operation with chemical engineers to achieve pragmatic commercial goals. For many years aspects of biochemistry and molecular genetics have been included in chemical engineering curricula, yet there has been little attempt until recently to teach aspects of engineering applicable to process design to biotechnologists. This textbook is the first to present the principles of bioprocess engineering in a way that is accessible to biological scientists. Other texts on bioprocess engineering currently available assume that the reader already has engineering training. On the other hand, chemical engineering textbooks do not consider examples from bioprocessing, and are written almost exclusively with the petroleum and chemical industries in mind. This publication explains process analysis from an engineering point of view, but refers exclusively to the treatment of biological systems. Over 170 problems and worked examples encompass a wide range of applications, including recombinant cells, plant and animal cell cultures, immobilised catalysts as well as traditional fermentation systems. * * First book to present the principles of bioprocess engineering in a way that is accessible to biological scientists * Explains process analysis from an engineering point of view, but uses worked examples relating to biological systems * Comprehensive, single-authored * 170 problems and worked examples encompass a wide range of applications, involving recombinant plant and animal cell cultures, immobilized catalysts, and traditional fermentation systems * 13 chapters, organized according to engineering sub-disciplines, are groupled in four sections - Introduction, Material and Energy Balances, Physical Processes, and Reactions and Reactors * Each chapter includes a set of problems and exercises for the student, key references, and a list of suggestions for further reading * Includes useful appendices, detailing conversion factors, physical and chemical property data, steam tables, mathematical rules, and a list of symbols used * Suitable for course adoption - follows closely curricula used on most bioprocessing and process biotechnology courses at senior undergraduate and graduate levels.

Book Synopsis Mathematical Modelling and Computer Simulation of Activated Sludge Systems by : Jacek Makinia
Download or read book Mathematical Modelling and Computer Simulation of Activated Sludge Systems written by Jacek Makinia and published by IWA Publishing. This book was released on 2020-03-02 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Modelling and Computer Simulation of Activated Sludge Systems – Second Edition provides, from the process engineering perspective, a comprehensive and up-to-date overview regarding various aspects of the mechanistic (“white box”) modelling and simulation of advanced activated sludge systems performing biological nutrient removal. In the new edition of the book, a special focus is given to nitrogen removal and the latest developments in modelling the innovative nitrogen removal processes. Furthermore, a new section on micropollutant removal has been added. The focus of modelling has been shifting in the last years to models that can describe the performance of a whole plant (plant-wide modelling). The expanded part of this new edition introduces models describing the most important processes interrelated with the mainstream activated sludge systems as well as models describing the energy balance, operating costs and environmental impact. The complex process evaluation, including minimization of energy consumption and carbon footprint, is in line with the present and future wastewater treatment goals. By combining a general introduction and a textbook, this book serves both intermediate and more experienced model users, both researchers and practitioners, as a comprehensive guide to modelling and simulation studies. The book can be used as a supplemental material at graduate and post-graduate levels of wastewater engineering/modelling courses.
