| Abstract | We have found that several species of probiotic bacteria are capable of producing spherical elemental Se nanospheres having an average diameter in the range of 50-500 nm when 10-10 000 mg Se L-1 was added to the medium in the form of selenite ions. In these bacteria, if the selenite concentrations above 1-2 mg L-1 seemingly induce detoxification processes, whereby the bacterium reduces selenite and excretes Se intracellularly in elemental form. This selenium form has a very low toxicity and a very good bioavailability. According to the toxicological and the feed testing experiments this Se form is a promising food and feed additive. |
