Effect of sulphur on selenium accumulation and speciation in Nannochloropsis oceanica

Sulphur (S) and selenium (Se) are chemically similar. Once Se is taken up, it substitutes S in S-containing amino acids. This study investigated the effect of S on selenite accumulation in the microalga Nannochloropsis oceanica. [0–28 mM] S concentrations and selenite concentrations of 0 and 30 µM w...
