Since the generation of the first transgenic mice in 1980, transgene technology has also been successfully applied to large farm animals. Although this technology can be employed to improve certain production traits of livestock, this approach has not been very successful so far owing to unwanted effects encountered in the production animals.

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 ...

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 ...

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 ...

Biotechnology and Bioengineering, 1990
AbstractThe fluid dynamic design and characterization of a low mechanical stress agitator and bioreactor vessel for large‐scale 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

Modelling of bioreactors [PDF]
Transactions of the Institute of Measurement and Control, 1986 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.

Microfluidic conductimetric bioreactor
Biosensors and Bioelectronics, 2007A microfluidic conductimetric bioreactor has been developed. Enzyme was immobilized in the microfluidic channel on poly-dimethylsiloxane (PDMS) surface via covalent binding method. The detection unit consisted of two gold electrodes and a laboratory-built conductimetric transducer to monitor the increase in the conductivity of the solution due to the ...

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.
