The separators and decanters from GEA Westfalia Separator ensure that the intracellular and extracellular enzymes are separated undamaged and in high concentrations.
Enzymes are complex organic protein compounds located in every living cell, where they are produced. They accelerate organic processes such as the breakdown of starch, protein, fat or sugar as catalysts, i. e. without being expended themselves. These valuable proteins are known to industry as esteemed helpers.
Glucose isomerase is an example of an enzyme which converts glucose into fructose and is highly significant in the starch industry. The enzyme is produced and remains in the cells of the employed microorganisms. To process it, the liquid phase of the fermentation broth is separated by centrifuging after fermentation. The concentrated microorganisms are treated further after centrifuging. The cell walls are broken down. Depending on the consistency of the suspension, it is diluted before the cell fragments are separated by continuously operating separators.
Separators and decanters from GEA Westfalia Separator are ideal for the optimum treatment of washing powder enzymes. Carefully purified and sterilized air is injected into a fermenter equipped with an agitator. The air bubbles are distributed in the nutrient solution, which is composed of carbohydrates, protein, growth agents and nutrients. This is sterilized, heated to an optimum temperature and then inoculated with the purified culture of a non-pathogenic microorganism. The microorganisms nourish themselves by converting the substances and simultaneously produce the enzymes. These are then excreted to the fermentation broth. After fermentation, the microorganisms are separated by adding a flocculent and centrifuging with separators and decanters. Succeeding stages of washing and polishing with centrifuges further increase the yield and the purity of the enzymes.
