abstract = "Radiation hormesis is a biological phenomenon whereby a relatively low doses of radiation
induce beneficial effects on biological parameters, such as viability, growth, and metabolic
profile 1. A number of studies have documented stimulatory effects of low-dose X- and
gamma radiation on plant growth 2. However, radiation hormesis has not been investigated
in microalgae which are becoming a highly relevant source of lipid-derived biofuels. The
aim of this study was to establish the effects of low-dose X-irradiation on biomass and
lipid production in Chlorella sorokiniana. The microalgae cultures were exposed to total
doses of 10, 20 or 50 Gy at different irradiation rates (0.565; 2.290 and 5.057 Gy/min).
Absorbed doses corresponded to ~10% of the total dose, as determined by dosimetry. Lipid
content was determined 30 days after irradiation using Nile Red fluorescence assay with
excitation/emission maxima at 530/570 nm (total lipids), 480/575 nm (neutral lipids) and
549/628 nm (polar lipids) 3,4. Lipid content was normalized to dry biomass.",
