Abstract excerpt
Although microalgae such as diatoms and haptophytes have been studied to optimize fucoxanthin production, the complete biosynthetic pathway of fucoxanthin remains unclear. In this study, we subjected the haptophyte Tisochrysis lutea cells to heavy-ion beam irradiation to induce random mutations and obtained two greenish strains, GR1 and GR2, following exposures to 45 and 100 Gy, respectively. The GR1 strain...
