INNOVATIVE SOLUTIONS FOR BIOTECH APPLICATIONS Fermentation Yeast Extract -More than just a nitrogen source

Yeast Extracts – What makes them unique? In the complex world of biotechnology and fermentation, Leiber brewers’ yeast extracts have proven to be more than just a nitrogen source! Yeast extracts have a long tradition in the fermentation industry, serving as a nutritious and effective complex nitrogen source for a broad spectrum of production microorganisms belonging to bacteria, fungi and yeasts. The production of beer, and thus the production of the by-product brewers’ yeasts is carried out mainly on the basis of renewable, natural raw materials such as barley, hops and water. The solids,...

Brewers' yeast extracts in biotech industry Brewers' yeast extracts from Leiber have found their way into countless applications, ranging from beverage production and straight forward fermentations for manufacturing of starter cultures, to complex processes of primary and secondary metabolites production. The possible applications are huge in industrial biotechnology, as well as in the field of fermented food and beverages. It is the perfect choice for applications from lab to big scale industrial fermentation. The following study shows the impact of brewers' yeast extracts applied as...

Yeast extracts are common products made by extracting the cell contents (removing the cell walls). They are used as complex nutrients for culture media for fermentation applications. Why yeast extract for fermentation? Yeast extracts are essential nutrients for production organisms deliver nitrogen in form of proteins and amino acids deliver vitamins, minerals and traces as important cofactors and stimulants deliver nucleotides as important growth factors Germany foodsales@leibergmbh.de
