Variation of antioxidant capacity and antiviral activity of the brown seaweed Sargassum filipendula (Fucales, Ochrophyta) under UV radiation treatments
Autor: Luz K. Polo, Fungyi Chow
Publikováno v: Applied Phycology, Vol 3, Iss 1, Pp 260-273 (2022)
Physiological responses in seaweeds are influenced by environmental conditions such as UV radiation among other abiotic factors, concerns that must be taken into account for bioprospecting purposes. The production of UV-absorbing compounds is a well-

Physiological performance by growth rate, pigment and protein content of the brown seaweed Sargassum filipendula (Ochrophyta: Fucales) induced by moderate UV radiation exposure in the laboratory
Autor: Luz K. Polo, Fungyi Chow
Publikováno v: Scientia Marina, Vol 84, Iss 1, Pp 59-70 (2020)
UV radiation is a factor affecting the distribution and physiology of photosynthetic organisms in an aquatic ecosystem. Studies with macroalgae indicate diverse biological disturbances in response to UV radiation. This work aimed to study sensitivity
