A process for an efficient phase separation of emulsions resulting from biphasic whole cell-bio-transformations has been developed at the TU Dortmund. The phase separation of unavoidable emulsions typically present due the presence of microorganisms and bio-surfactants, which has previously been seen as problematic, has been greatly simplified to permit further processing of the reaction mixture. In contrast to other approaches such as the use of de-emulsifiers or centrifuges a phase separation can be achieved with a minimal effort in both energy and equipment. Using a physical effect the new methods enables a high potential for an industrial application due to its scalability, low costs and easy process control.
The exoplanet 51 Pegasi b [1] lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as…
The invention concerns a T-cell based immunotherapy using peptides which are derived from human membrane protein desmoglein. By applying a medical preparation including a peptide or a combination of peptides, a specific immunological tolerance is triggered. Therefore, the clinical signs of pemphigus vulgaris disease improve, because the base for disease is deprived.
