This book was released on 2018-10-31 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the manufacture of bio-therapeutics the importance of a well-known process is key for a high product titer and low batch to batch variations. Soft sensors are based on the concept that online sensor signals can be used as inputs to mathematical models to derive new valuable process information. This information could then be used for better monitoring and control of the bioprocess. The aim of the present thesis has been to develop soft sensor solutions for upstream bioprocessing and demonstrate their usefulness in improving robustness and increase the batch-to-batch reproducibility in bioprocesses. The thesis reviews the potential and possibilities with soft sensors for use in production of bio-therapeutics to realize FDA´s process analytical technology (PAT) initiative. Modelling and hardware sensor alternatives which could be used in a soft sensor setup are described and critically analyzed. Different soft sensor approaches to control glucose feeding in fed-batch cultures of Escherichia coli are described. Measurements of metabolic fluxes and specific carbon dioxide production was used as control parameters to increase product yield and decrease the variability of produced recombinant proteins. Metabolic heat signals were used in uninduced cultures to estimate and control the specific growth rate at a desired level and thereby also estimate the biomass concentration online. The introduction of sequential filtering of the signal enabled this method to be used in a down-scaled system. The risk and high impact of contaminations in cell cultures are also described. An in situ microscope (ISM) was used as an online tool to estimate cell concentration and also to determine cell diameter size which enabled the detection of contaminant cells at an early stage. The work presented in this thesis supports the idea that soft sensors can be a useful tool in the strive towards robust and reliable bioprocesses, to ensure high product quality and increased economic profit.

Download or read book Development of Soft Sensors for Monitoring of Chinese Hamster Ovary Cell Processes written by Seyed Kaveh Ohadi and published by . This book was released on 2014 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this work was to develop monitoring techniques for use during the production of monoclonal antibodies (Mabs) in Chinese hamster ovary cell cultures. Such monitoring would enable real-time screening and control of key process variables both upstream and downstream so as to guarantee product quality and process consistency. The measurement techniques that are currently available are time and labor intensive and in some cases require frequent maintenance. Thus, they are not suitable for fast online monitoring of bioprocesses. Thus, with a goal of future real-time implementation, data-driven (empirical models) and model-driven (mechanistic models) soft sensors were developed. The bioreactor is the key component of the upstream manufacturing phase. Continuous monitoring and control of this unit is critical in order to maximize production of the Mab with a desired quality (i.e. glycosylation pattern). Data-driven soft sensors were developed using intrinsic multi-wavelength fluorescence spectra of the culture broth in combination with partial least square regression (PLSR) for tracking viable cell, dead cell, recombinant protein, glucose, and ammonia concentrations. To better elucidate the relationship between the fluorescence spectra and process operating conditions, trajectories of fluorophore-peaks over the course of the culture were investigated and compared to changes in key process variables prior to model development. The proposed soft sensors were capable of predicting the aforementioned process variables with high accuracy. To enhance the extrapolation accuracy of the data-driven soft sensor outside of the region of operating conditions used for model calibration and to better track the dynamics of the culture, an extended Kalman filter (EKF) was developed based on a combination of mechanistic and empirical models. To address the structural and parameter uncertainty of the models, non-stationary disturbances were introduced to the model through parameter adaptation. The resulting EKF-based soft sensor's predictions surpassed the accuracy of a standalone fluorescence based soft sensor and was capable of tracking process dynamics in between sampling instances with high precision. N-linked glycosylation has a significant impact on the therapeutic properties of Mab and is an important quality attribute that is associated with the extracellular metabolic state of the culture. Based on the primary investigation it was revealed that the fluorescence spectroscopy is not capable of accurately tracking the glycosylation profile of the Mab. Thus, to enhance the controllability of the glycoprofile, a novel dynamic model was developed that relates the extracellular culture conditions to the accumulated glycosylation pattern of Mab produced through the production of nucleotide sugars required for N-linked glycosylation in the Golgi apparatus. The model parameters were estimated using the experimental data. The resulting model was capable of accurately predicting the glycosylation extent in the form of a galactosylation index as well as individual glycan structures. Another area of application of fluorescence was for monitoring protein aggregation. During downstream processing proteins are exposed to stress factors such as changes in temperature, pH, or shear stress that can increase the propensity of Mab to aggregate. Aggregation can trigger undesirable impacts including an increased immunogenicity response in the patient. Therefore, developing an in situ technique for fast quality and quantity control of protein aggregation is of great industrial interest. Fluorescence-based soft sensors, in conjugation with PLSR, were developed for quality control (product classification) and for quantitative monitoring (Mab monomer concentration) at different process conditions that typically occur in different stages of the purification process. To better elucidate the impact of stress factors on the degree of aggregation and identify the operating conditions for which the propensity to aggregate is minimal, a surface response model was fitted to the data prior to soft sensor development. The soft sensors were capable of accurately predicting monomer concentration of samples exposed to different levels of stress factors as well as for classifying the final product into different groupings according to their relative aggregation levels.

Download or read book Bioprocess Monitoring and Control written by Bernd Hitzmann and published by . This book was released on 2020-09-10 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Process monitoring and control are fundamental to all processes; this holds especially for bioprocesses, due to their complex nature. Usually, bioprocesses deal with living cells, which have their own regulatory systems. It helps to adjust the cell to its environmental condition. This must not be the optimal condition that the cell needs to produce whatever is desired. Therefore, a close monitoring of the cell and its environment is essential to provide optimal conditions for production. Without measurement, no information of the current process state is obtained. In this book, methods and techniques are provided for the monitoring and control of bioprocesses. From new developments for sensors, the application of spectroscopy and modelling approaches, the estimation and observer implementation for ethanol production and the development and scale-up of various bioprocesses and their closed loop control information are presented. The processes discussed here are very diverse. The major applications are cultivation processes, where microorganisms were grown, but also an incubation process of bird's eggs, as well as an indoor climate control for humans, will be discussed. Altogether, in 12 chapters, nine original research papers and three reviews are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Readers will find a multidisciplinary approach elucidating all the important features of green hydrogen so that science researchers and energy engineers as well as those in economics, political science and international relations, will also find value. Energy sources and generation is the foremost concern of all governments, NGOs, and activist groups. With Green New Deals and reduced or net zero emission goals being implemented on a global scale, the quest for economic, scalable, efficient, and sustainable energy systems has reached a fever pitch. No one energy source ticks all the boxes and new energy technologies are being developed all the time as potential disruptors. Enter green hydrogen with zero emissions. Hydrogen is a rare gas in nature and is often found together with natural gas. While hydrogen is the most abundant element in the known universe, molecular hydrogen is very rare in nature and needs to be produced—and produced in large quantities, if we are serious about the Green Deal. This book has been organized into three parts to introduce and discuss these crucial topics. Part I discusses the Green Deal and the current state and challenges encountered in the industrialization of green hydrogen production, as well as related politics. Chapters in this section include how to decarbonize the energy industry with green hydrogen, and one that describes a gradual shift in the approach of hydrogen production technologies from non-renewable to renewable. Part II is devoted to carbon capturing and hydrogen. Chapters on biomass mass waste-to-hydrogen conversion and related efficient and sustainable hydrogen storage pathways, life cycle assessment for eco-design of biohydrogen factory by microalgae, and metal oxide-based carbon capture technologies are all addressed in this section. The third and final part of the book was designed to present all features of green hydrogen generation. Chapters include PEM water electrolysis and other electrolyzers, wind-driven hydrogen production, and bifunctional electrocatalysts-driven hybrid water splitting, are introduced and thoroughly discussed. Audience This book is directed to researchers and industry professionals in energy engineering, chemistry, physics, materials science, and chemical engineering, as well as energy policymakers, energy economists, and others in the social sciences.
