Integration of Product Recovery in Microbial Advanced Biofuel Production: Overcoming Emulsification Challenges

Bulk Dynamics of Droplets in Liquid-Liquid Axial Cyclones

Separation of oil and water is an essential step in the treatment of the production streams from fossil oil wells. Settling by gravity is a robust though voluminous process and therewith expensive method at remote locations, leading to a need for smaller separation equipment. In this thesis, we describe the research performed on the development...

Recovery of bio-based butanol

Product recovery is crucial for fermentative butanol production. Bio-based fermentative butanol production systems benefit from answering the question to what extent, and in which form, integration between fermentation and product recovery should be applied. The product recovery is applied in order to minimize the impact of butanol inhibiting...

Production and deposition of well defined aerosol nanoparticles for studies of basic properties

The search for new materials and material properties has advanced to smaller and smaller structures during the past years. Inorganic particles in the size range below {100 nm} are interesting for many applications, because on this scale properties often vary strongly from bulk. Nanoparticles are traditionally produced on large scale in wet...

Bioseparations using surfactant-aided size-exclusion chromatography

In most bioprocesses one or more chromatographic steps are used in the purification of the product. Size-exclusion chromatography (SEC) is often one of these chromatographic steps. It is based on the difference in size and shape of the components to be separated and is used for the separation of molecules with a near identical chemical...

Selective recovery of micrometer bioparticles using aggregation and air flotation

Air flotation is a separation technique that makes use of the air-water interface for separation of particles and molecules from mixtures. This thesis discusses its use for separation of bioparticle mixtures. Particulate bioproducts, such as crystals, inclusion bodies, virus-like particles and precipitates, can be produced inside microbial cells...
