Ohly's X-SEED® yeast-based bionutrients are a powerful tool for the biotechnology industry to achieve high yields, titers and productivity in fermentation processes. They are a balanced source of complex nutrients and contain amino acids, peptides, vitamins, minerals as well as growth factors and nucleotides.  

Fermentation is a sustainable production method for food ingredients, biochemical and enzymes using bacteria, yeast and fungi as the production host. To execute a fermentation process that is fast and efficient, supplying these micro-organisms with nutrients is of key importance. But there are very many different fermentation processes, from the production of probiotics to insulin and feed additives. Each of these fermentation processes has its specific production host and process conditions, resulting in unique nutrient requirements. Ohly has a diverse portfolio of yeast-based nutrient solutions to give the optimal nutrient mixture for each specific process.

Yeast Extracts

X-SEED® yeast extracts are a complete source of bionutrients for your fermentation process. The inclusion of yeast extract in the growth medium will increase the productivity, titer and yield of your process.

Enriched Yeast Extract

Certain micro-organisms require additional specific bionutrients beyond what is naturally present in a regular yeast extract. X-SEED® enriched yeast extracts can cover these higher nutrient demands, resulting in further optimization of your fermentation process.

Yeast Peptone

Some micro-organisms prefer peptides over free amino acids as their complex nitrogen source. Ohly offers several X-SEED® peptone products produced from yeast protein that are non-GMO, animal-free, allergen-free, Kosher and Halal.

Inactive Yeast

The use of inactive yeast, instead of yeast extracts or peptones, provides a release of nutrients from the yeast cell during your fermentation process. This can avoid inhibition of productivity by the presence of high concentrations of specific nutrients, especially at the start of your process.
