Current Opinion in Biotechnology, 1997
A very wide range of methods has recently been employed to selectively partition fermentation products, substrates, or other metabolites to achieve an overall improvement in bioprocess performance. Techniques ranging from extraction and gas stripping to electrokinetic methods have been used to favorably influence the microenvironment of cells being ...

Bioreactors in Tissue Engineering
Technology and Health Care, 2010A bioreactor can be defined as a device that uses mechanical means to influence biological processes. In tissue engineering bioreactors can be used to aid in the in vitro development of new tissue by providing biochemical and physical regulatory signals to cells and encouraging them to undergo differentiation and/or to produce extracellular matrix ...

Hydrometallurgy, 1999
A survey of the literature on biohydrometallurgical topics revealed that the papers devoted to bioreactors amount to less than 5 % of the total and refers mainly to the analysis of the performance and m design guidelines of stirred tank and of bubble column machines, the so-called Pachuca tanks.

Enzymes are pliable systems and core cellular components allowing the performance of several processes. They can also be utilized as "green" synthetic factories to generate bioactive therapeutic, diagnostic or theranostic compounds. Methods to enable the mapping of enzyme substrates as well as the understanding of the interactions of the formed ...

Modelling of bioreactors [PDF]
Biochemical reactors pose special problems in that they are essentially concerned with living systems. The consequences of this is that the bio transformations are complex and require detailed consideration, especially since instabilities can easily occur if the concentration of species is not controlled carefully.

Biotechnology and Bioengineering, 1990
AbstractThe fluid dynamic design and characterization of a low mechanical stress agitator and bioreactor vessel for largeāscale bioprocessing using anchorage dependent mammalian cells is considered. The complex and fragile nature of mammalian cells puts stringent constraints on the design of agitators for stirred tank bioreactors. Traditional agitators

Bioreactors: Design and Operation
Science, 1983The bioreactor provides a central link between the starting feedstock and the product. The reaction yield and selectivity are determined by the biocatalyst, but productivity is often determined by the process technology; as a consequence, biochemical reaction engineering becomes the interface for the biologist and engineer.

Bioprocess and Biosystems Engineering, 2001
Analysis of bioreactors is central for successful design and operation of biotechnical processes. The bioreactor should provide optimum conditions, with respect to temperature, pH and substrate condition, for example, besides its basic function of containment. The ability to control the substrate concentration is an important function of the bioreactor.

Bacteriophage Production in Bioreactors
2017The optimal conditions for the production of virulent bacteriophages in bioreactors can vary greatly depending on the host-bacteriophage system used. We present a general method for the production of virulent bacteriophages in bioreactors that can be adapted to many host-bacteriophage systems and various operating conditions (reactor volume, medium ...
