Summary

Out of 51 strains tested (incl. 37 isolated from special habitats), the wild-type yeast strain Meyerozyma guilliermondii produced the highest riboflavin concentration in the screening procedure. A fermentation strategy at a laboratory scale is provided, where a yield of 30 mg riboflavin per g dry matter of yeast cells was achieved.


EPrint Type:Practice tool
What problem does the tool address?:Supplementation of vitamin B2 (riboflavin) in poultry feed is essential. For organic farming, non-GMO derivative riboflavin is required. The only products on the market that are not produced with the help of GMOs are more expensive than the conventional products,and their legal status still needs to be clarified at the EU level.
What solution does the tool offer?:Screening non-GM wild-type yeast strains overproducing riboflavin is the first step in developing GMO-free riboflavin production lines that ensure a continuous supply of riboflavin for organic livestock.
