Abstract:

The effects of additional Mg²⁺ on the growth and lipid accumulation of the microalgae Monoraphidium sp. FXY-10 under mixotrophic conditions were investigated. 100 μmol Mg²⁺ were added to the growth media during the stationary growth phase. Compared with the control (35.25%), the highest lipid content reached up to 37.13% biomass after Mg²⁺ was added to the media. Moreover, the higher lipid productivity of 79.83 mg L¹ d¹ and the biomass productivity of 214.65 mg L¹ d¹ were attained in the Mg²⁺-supplemented cultures, as compared with cultures without supplemented (72.95 mg L¹ d¹ and 179.28 mg L¹ d¹, respectively). The use of Mg²⁺ supplements were proven to stimulate cell regrowth, prolong the stationary phase, and promote lipid accumulation in Monoraphidium sp. FXY-10.
