Oxygen Transfer Characteristics of Miniaturized Bioreactor Systems
Since their introduction in 2001 miniaturized bioreactor systems have made great advances in function and performance. In this article the dissolved oxygen (DO) transfer performance of submilliliter microbioreactors, and 1-10 mL minibioreactors was examined. Microbioreactors have reached k(L) a values of 460 h(-1) , and are offering instrumentation and some functionality comparable to productio...
متن کاملA Bioreactor System Based on a Novel Oxygen Transfer Method
JUNE 2008 B ioreactor technologies for mammalian cell culture may seem quite sophisticated (1). In fact, efficient mammalian cell culture is simple and requires just two major elements: mixing and oxygen (O2) transfer. Traditional methods for mixing use an impellor, and the classical O2 transfer method features a sparging stone that expels air bubbles to increase the O2 transfer surface area in...
متن کاملQuantification of power consumption and oxygen transfer characteristics of a stirred miniature bioreactor for predictive fermentation scale-up.
Miniature parallel bioreactors are becoming increasingly important as tools to facilitate rapid bioprocess design. Once the most promising strain and culture conditions have been identified a suitable scale-up basis needs to be established in order that the cell growth rates and product yields achieved in small scale optimization studies are maintained at larger scales. Recently we have reporte...
متن کاملModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon Impeller
Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of k...
متن کاملOptimization of oxygen mass transfer in a multiphase bioreactor with perfluorodecalin as a second liquid phase.
Oxygenation is an important parameter involved in the design and operation of mixing-sparging bioreactors and it can be analyzed by means of the oxygen mass transfer coefficient (k(L)a). The operational conditions of a stirred, submerged aerated 2-L bioreactor have been optimized by studying the influence of a second liquid phase with higher oxygen affinity (perfluorodecalin or olive oil) in th...
