Phyterra Yeast Inc.'s primary focus is to develop and commercialize advanced urea-degrading yeast products to reduce a known naturally occurring carcinogen Ethyl Carbamate. These yeasts are designed to drastically reduce urea, one of the primary precursors of Ethyl Carbamate. Ethyl Carbamate, also known as urethane, is found in many commonly-consumed yeast-fermented foods and beverages, such as wine, brandy, whiskey, sake, bread, soy sauce, sherry and beer and is a direct byproduct of the use of yeast to ferment foods and beverages
