Some micro-organisms require a higher level of certain nutrients beyond what is naturally present in a regular yeast extract. In addition, the product being produced by fermentation or the fermentation conditions employed can have the same effect. In this case to ascertain efficient fermentative production, Ohly’s enriched yeast extracts can meet the enhanced requirements of specific nutrients. By using different yeast extract production processes, higher concentrations of particular nutrients or growth factors in the yeast extract can be achieved. Using Ohly’s yeast extracts with enhanced vitamin or nucleotide levels enables you to grow and produce efficiently with micro-organisms that have such higher nutrient demands.
