Abstract: A method for producing a crystalline and/or amorphous metabolite suspension from a cell fermentation broth in a continuous centrifuge process comprising (a) adding at a separate inlet to the centrifuge the fermentation broth comprising the cells and the metabolite of interest, wherein the metabolite is partly or wholly on crystalline and/or amorphous form; (b) adding at another inlet to the centrifuge an aqueous liquid comprising a salt and/or a carbohydrate having a higher density than the cells and a lower density than the metabolite of interest in its precipitated form; (c) removing the cells at a separate outlet to the centrifuge; and (d) removing the suspension comprising the crystalline and/or amorphous metabolite of interest at another outlet to the centrifuge.

Abstract: A method of flocculating a bacterial cell, producing a protein of interest, from a fermentation broth, comprising a) diluting the fermentation broth up to 1000% (w/w) with water; b) adding a divalent salt to a concentration in the fermentation broth of more than 10 milli moles per liter diluted fermentation broth; c) adjusting the phosphate concentration to a concentration in the fermentation broth of more than 10 milli moles per liter diluted fermentation broth; d) adjusting the pH of the diluted fermentation broth to a pH within the range of 6.1-10.5; and e) removing the bacterial cells, whereby a protein solution with a turbidity of less than 100 NTU is obtained.

Abstract: A method and an equipment for monitoring the syntrophic relations between different parts of a bacterial consortium in the process fluid of a biological process plant, such as a biological gas plant or waste water treatment plant, through a chromatographic measurement of the content of the individual volatile fatty acids in consecutive samples of the process fluid, the samples being acidified and filtered prior to the chromatographic separation

Abstract: A method for withdrawing and filtering a partial volume of a particle-containing process fluid enclosed in a container, a combination of a container enclosing a process fluid and an assembly for continuously withdrawing and filtering a partial volume of a process fluid and a cross-flow filtering device are disclosed. The method, the assembly and the filtering device can be used in connection with biological process systems, in which the removal of sand, sludge, fibers and alike from partial volumes of the process fluid is necessary before additional filtration and subsequent sample analysis.
