The calves have an immature immune system as they lack immunoglobulins (Igs). Subsequently, the supply of good quality bovine colostrum is required. The quality of colostrum is classified by low bacterial counts and adequate Ig concentrations. Bacterial contamination can contain a variety of human pathogens or high counts of spoilage bacteria, which has become more challenging with the emerging use of bovine colostrum as food and food supplements. There is also a growing risk for the spread of zoonotic diseases originating from bovines. For this reason, processing based on heat treatment or other feasible techniques is required. This review provides an overview of literature on the microbial quality of bovine colostrum and processing methods to improve its microbial quality and keep its nutritional values as food. The highlights of this review are as follows: high quality colostrum is a valuable raw material in food products and supplements; the microbial safety of bovine colostrum is increased using an appropriate processing-suitable effective heat treatment which does not destroy the high nutrition value of colostrum; the heat treatment processes are cost-effective compared to other methods; and heat treatment can be performed in both small- and large-scale production.}}, author = {{Fasse, Sylvia and Alarinta, Jarmo and Frahm, Björn and Wirtanen, Gun}}, booktitle = {{Dairy}}, issn = {{2624-862X }}, keywords = {{bovine colostrum, bacteria, pathogens, probiotic bacteria, cost-effective processing, heat treatment, pasteurization, contamination control, immunoglobulins, enzymes}}, number = {{4}}, pages = {{556--575}}, publisher = {{MDPI}}, title = {{{Bovine Colostrum for Human Consumption - Improving Microbial Quality and Maintaining Bioactive Characteristics through Processing}}}, doi = {{10.3390/dairy2040044}}, volume = {{2}}, year = {{2021}}, } @inbook{7983, abstract = {{For the manufacturing of complex biopharmaceuticals using bioreactors with cultivated mammalian cells, high product concentration is an important objective.

Five clonal Chinese hamster ovary cell populations were analyzed based on the data of a 3-month-stability study. We adapted a mechanistic cell culture model to the experimental data of one such clonally derived cell population. Uncertainties and prior knowledge concerning model parameters were considered using Bayesian parameter estimations. This model was used then to define an inoculum train protocol. Based on this, we subsequently simulated the impacts of differences in growth rates (±10%) and production rates (±10% and ±50%) on the overall cultivation time, including making the inoculum train cultures; the final production phase, the volumetric titer in that bioreactor and the ratio of both, defined as overall process productivity.

This can be challenging in the presence of low sampling frequencies (e.g. every 24 h), different consecutive scales and large measurement errors, as in the case of cell culture seed trains. This contribution presents an iterative learning workflow which generates and incorporates knowledge concerning cell growth during the process by using a moving horizon estimation (MHE) approach for updating of model parameters. This estimation technique is compared to a classical weighted least squares estimation (WLSE) approach in the context of model updating over three consecutive cultivation scales (40–2160 L) of an industrial cell culture seed train. Both techniques were investigated regarding robustness concerning the aforementioned challenges and the required amount of experimental data (estimation horizon). It is shown how the proposed MHE can deal with the aforementioned difficulties by the integration of prior knowledge, even if only data at two sampling points are available, outperforming the classical WLSE approach.

One of them is the power supply of factories. Here lies the origin of the upheaval in drive technology, which today is already based on direct current, while the grid supplies alternating current. In this book you will learn the advantages of building a comprehensive direct current factory network into which all power generators feed their energy and from which all consumers are supplied directly. All related conceptual, economic, technical and organizational issues are dealt within this book: - Potential and economic assessment of the direct current factory in comparison with a current factory supplied with alternating current - System concept draft for the necessary system and device adjustments with concrete solutions for implementation - Detailed treatment of all relevant technical topics, such as topology, voltage level, supply concepts, grounding and network types, EMC, pre-charging - Characteristic-based control of a direct current network with different supply devices and loads - Guarantee of network stability, even with highly dynamic loads and without additional communication - Treatment of essential security aspects - Planning and design of a direct current network in your own factory, including presentation of the planning tasks and instructions for the user}}, author = {{Borcherding, Holger and Austermann, Johann and Spanier, Patrick and Sauer, Alexander}}, editor = {{Alexander, Sauer}}, isbn = {{978-3-446-47174-0}}, pages = {{214}}, publisher = {{Hanser}}, title = {{{The DC-Factory - Energy efficient.
