Selenium yeast is a nutrient-rich yeast. Using molasses as raw material, adding nitrogen source, phosphorus source, and other nutrient sources, after fermentation and culture, selenium element is added in the yeast growth process and inorganic selenium is converted into organic selenium in yeast cells through a special fermentation process.
Selenium Yeast is selected from the high biomass of Se enriched yeast species. Selenium was added to the culture medium to enrich selenium in yeast in the form of organic selenium. Yeast selenium is a new and green organic selenium source for feeding.
