A fermentation starter or starter culture is a preparation that’s used to kick-start the fermentation process in a number of diverse industries, from food & renewables to biotechnology and pharmaceutical.
In the pharmaceutical industry, bacteria are used to produce antibiotics, vaccines and medically useful enzymes. The biotechnology industry uses bacterial cells for the production of biological substances that are useful to human existence, including fuels, foods, medicines, hormones, enzymes, proteins and nucleic acids, resulting in the development of human hormones such as insulin, enzymes such as streptokinase, and human proteins such as interferon and tumor necrosis factor. These products are used for the treatment of a various medical conditions and diseases, including diabetes, heart attack, tuberculosis, AIDS and SLE (lupus).
Starter cultures are derived from undefined, empirically produced species to attain an end-product with predictable and reproducible quality and quantity characteristics. The production of starter cultures can be divided into two sections.
After fermentation, the bacteria must be processed and separated from the fermentation solution, comprising the cultured micro-organisms and the remainder of the nutrient solution. First, the bacteria are separated from the liquid phase and concentrated: nozzle and self-cleaning steam-sterilizable disc separators are available for this step of the process.
The concentrated culture is then transferred to a freeze dryer (lyophilizer) and dried. Finally, the cultures are packaged under airtight conditions and stored at low temperatures.
The careful treatment of the active culture, sterility and high separation efficiencies are prerequisites for the economical, reliable and efficient processing of bacterial starter cultures. As such, separators from GEA are equipped with hydrohermetic product feed systems that minimize the shear forces experienced when the product enters the bowl, which maintains the viability of the cells.

Le testate di compressione di GEA sono il cuore pulsante dell'omogeneizzatore poiché attivano il processo di omogeneizzazione pompando il prodotto ad alta pressione per convogliarlo all'interno della valvola di omogeneizzazione.
GEA's thorough understanding of the lyophilization process enables them to supply a comprehensive range of products and services, comprising laboratory equipment, pilot plants for research and small-scale production batches, industrial size pharmaceutical production freeze dryers.
Gli omogeneizzatori da laboratorio GEA, piccoli e compatti, consentono di testare gli effetti dell'omogeneizzazione sul prodotto e valutare quali sono i migliori parametri di processo.
Gli omogeneizzatori industriali GEA sono costituiti da due elementi essenziali: un blocco di compressione che consente di pompare il prodotto ad alta pressione e una valvola di omogeneizzazione, in grado di micronizzare le particelle disperse fino a un ordine di grandezza micrometrica e nanometrica, a seconda delle caratteristiche del prodotto e ...
In a dairy herd, every cow has her own story – and modern herd management tools help tell it. By tracking health, habits and needs, these smart systems let farmers care better, work smarter and keep milk flowing. It's the secret behind happy herds and successful, more sustainable dairy farming.
La riduzione degli sprechi è importante per GEA e, sfruttando le potenzialità della tecnologia di liofilizzazione, possiamo trasformare le eccedenze alimentari in prodotti di valore e di lunga durata, contribuendo a ridurre gli sprechi, a prolungare la durata di conservazione e a creare maggiore resilienza nel sistema di approvvigionamento alimentare per le generazioni a venire.
