Fatty acid metabolism of marine microalgae
… were elucidated in two heterotrophic, marine microalgae; Schizochytrium sp. and Crypthecodinium cohnii. PUFA-requiring auxotrophs of both of these algae were created and used as tools for studying PUFA biosynthetic pathways. Additionally, equilibrium radio-labeling techniques were applied to …

Transient heterologous protein expression in green microalgae
… safety and scalability. The potential of green microalgae as an innovative heterologous expression system for the production of recombinant proteins is examined in this thesis. To enable this, more specifically, the preparation of algal biomass of various axenic isolates, and their incorporation …

Anti-aging potential of some freshwater microalgae extracts
The aging of the skin is a progressive, multi- faceted phenomenon that alters skin tissue and is impacted by both intrinsic and external causes. Age and genetics contribute to intrinsic aging, whereas ultraviolet radiation (UVR) contributes to extrinsic aging. Intrinsic aging is a predetermined …
