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. The separators and decanters from GEA Westfalia Separator Group ensure that the intracellular and extracellular enzymes are separated undamaged and in high concentrations. Production of intracellular enzymes Glucose isomerase is an example of an enzyme which converts glucose into fructose...

Starter cultures are now an established part of the food, medical product and animal feed industries. They are responsible for predictable and reproducible product quality and thus for controllable production processes. Probiotic products are also becoming more...

from the liquid phase. Nozzle and self-cleaning disc separators in steam-sterilised design are available for this step of the process. The concentrated lactobacilli then pass to a freeze drier. Finally, the cultures are packaged under oxygen exclusion and stored at low temperatures. This retains their activity for months before they are processed, e. g. as “live cultures” in probiotic yoghurts. Sterility and careful treatment The careful treatment of the living microorganisms, sterility and a high separation efficiency are prerequisite to the economical, reliable and efficient processing. The...

Vaccines Protection against germs Vaccines are medicines which immunise human or Process of vaccine manufacturing animal organisms against diseases. The organism When a suitable virus strain has been chosen, it is to be protected is repeatedly exposed to small isolated in ampoules and stored at -192 °C in liquid quantities of antigens (vaccines) or antibodies in nitrogen. Breeding is then conducted starting with the form of a serum. This achieves immunity. the pre-fermenter and continuing in the main fermenter. The fermentation process is supplemented Live vaccines by a nutrient solution. The...

Non-live vaccines In serum therapy, the infected organism is supplied with the sera produced with the antibodies of immunised individuals. Sera are gained by multiplying bacteria in a suitable nutrient solution. The serum produced during fermentation is excreted by the cells into the fermentation solution. The serum is isolated by separating the biomass in centrifuges and by further stages of processing in the clarification phase. An aseptic process is essential in the production of vaccines and sera. ^14 Aeration Starter culture Dried nutrients Water Pre-fermenter Nutrient tank Virus culture...
