Popis: The production of fucoxanthin and fatty acids in Conticribra weissflogii has been examined, but there is still a lack of understanding regarding the impact of trace elements, including iron, on their co-production. To address this knowledge gap, this study investigated the effects of FeCl3·6H2O on the growth, fucoxanthin, and fatty acids of C. weissflogii. The findings revealed that the highest cell density (1.9 × 106 cells mL−1), cell dry weight (0.89 ± 0.15 g L−1), and total fatty acid concentration (83,318.13 µg g−1) were achieved at an iron concentration of 15.75 mg L−1, while the maximum carotenoid and fucoxanthin contents were obtained at an iron concentration of 3.15 mg L−1. The study demonstrated that the content of the active substance in C. weissflogii could be increased by adjusting the iron concentration, providing new information as to the more efficient co-production of fucoxanthin and fatty acids and offering experimental support for large-scale production.
