Elemental, Nano-Sized (100-500 nm) Selenium Production by Probiotic Lactic Acid Bacteria

Abstract—Selenium is well known as an essential trace element since the 20th century, but it can be overdosed easily because of its toxicity. According to the present regulations [1] only the potentially most harmful, inorganic selenium salts can be added to any comestibles. Elemental selenium is considered as the least toxical of all selenium forms and in the same time supplementation with its nano-size particles has the same or better bioavailability compared to its salts. In our experiments we managed to produce nano-size (100-500nm) elemental selenium by using probiotic yogurt bacteria in a fermentation procedure. We developed the laboratory technology of product purification and recovery from bacteria.

Index Terms—Antioxidant, Food Supplement, Lactic Acid Bacteria, Nanosphere, Selenium.
