Simulating Process Limitations in Microbial Cultivation: A Parallel Two-Compartment Scale-Down Approach

Simulating Process Limitations in Microbial Cultivation: A Parallel Two-Compartment Scale-Down Approach

29 Feb 2016

In large-scale industrial bioprocesses, the presence of gradients in critical process parameters, such as dissolved oxygen (DO), pH, and substrate concentration, can be observed. They result in inhomogeneous growth conditions within the bioreactor/fermenter and can affect cell yield and/or productivity. This application note describes the effects of oscillating DO and substrate concentration. This study exemplifies the benefits of flexible bench scale bioreactor solutions and advanced bioprocess control software. Individual control of parallel operated bioreactors allowed different vessel sizes, individual parameter set-points, and multiple cultivation phases to be implemented easily.

Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Bioprocessing / FermentationBioprocessing is the use of biological materials to perform commercial, scientific or medical research processes. Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.BioreactorBioprocessingBioprocessing is the use of biological systems for the conversion of raw materials to desired products. This includes the research, development and manufacturing stages of production and can refer to food processing, small-molecule pharmaceutical manufacture, production of recombinant protein therapeutics, or the generation of renewable energy.BiopharmaceuticalsBiopharmaceuticals are proteins and other compounds (such as nucleic acids) produced by living organisms that have uses as therapeutics or for in vivo diagnostics. The most well known example of a biopharmaceutical product, and the first to be approved for therapeutic use, was recombinant human insulin.Cell GrowthCell growth refers to the process by which cells increase in size and number. It is essential for tissue development, wound healing, and cancer research. Understanding and controlling cell growth is a fundamental part of cell biology and regenerative medicine.
