Selenium is an essential element in many organisms, with beneficial roles for animal health, but it can also be a dangerous toxin. Research into these two paradoxical faces of selenium is reviewed in relation to unicellular species of microalgae. Recent information on algal selenoproteins in general, and selenium-containing enzymes in particular, will be described, as well as the bioaccumulation of different forms of selenium in algae. In this review, we will also consider the impact of selenium on algal growth and other cellular events: firstly from the point of its toxicity, including research into selenium-resistant algal strains and their possible use for remediation of selenium contaminated environments. Secondly, we will examine case examples of selenium-enriched algae as a source of organic selenium with health benefits for different domestic animals.
