Modeling the Separation of Microorganisms in

Bioprocesses for the production of renewable energies and materials lack efficient separation processes for the utilized microorganisms such as algae and yeasts. Dissolved air flotation (DAF) and microflotation are promising approaches to overcome this problem. The efficiency of these processes depends on the ability of microorganisms to aggregate with microbubbles in the flotation tank.

Separation, Characterization, and Handling of Microalgae ...

Dielectrophoresis-based microfluidic devices have been long established as promising tools for label-free handling, characterization, and separation of broad ranges of cells. The technique is based on differences in dielectric properties and sizes, which results in different degrees of cell movement under an applied inhomogeneous electrical field.

The separation of the microorganisms from their original matrices may reduce this problem of interference. Techniques based on the density gradient centrifugation to remove microorganisms from their ecosystem were first optimized on soil samples ( 3 , 7 , 9 , 17 , 20 ) and were thereafter extended to other matrices, like sediments ( 2 ).

2014-2-17 · Flotation is a widely used method for separation of DNA (Okamoto et al. 1998), virus particles or parts of cells (Jones and Matus 1974). However, this is the first study to report the use of flotation for the separation of bacteria. The use of the hydrostatic pressure of the FA is the underlying principle of flotation.
