the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...

Phytohormones are present in seaweeds but little is known about occurrence and content of them in seaweeds of Persian Gulf. The aim of this study was extraction of abscisic acid and gibberellin in Sargassum muticum and Gracilaria corticata. The seaweeds were collected bimonthly over one year at Bushehr coasts, Persian Gulf, during a range of environmental conditions. We explored new HPLC method...

The Anticancer Effects of Sargassum Boveanum Hydroalcoholic Extract in Human Colorectal Cancer Cell Lines

Blooms and coastal inundations of pelagic Sargassum have caused major problems to communities ecosystems throughout the tropical Atlantic over past decade. Understanding growth, movement, mortality is essential being able predict mitigate these events. In principle, cyclones that occur in this area could an impact on all three processes. a recent article, Sosa-Gutierrez et al. (2022, https://do...

A phytochemical investigation of a southern Australian marine brown alga, Sargassum paradoxum, resulted in the isolation and identification of four new (5, 9, 10, and 15) and nine previously reported (1, 2, 6-8, and 11-14) bioactive meroditerpenoids. HPLC-NMR and HPLC-MS were central to the identification of a new unstable compound, sargahydroquinal (9), and pivotal in the deconvolution of eigh...

Seaweed cultivation is a high growth industry that is primarily targeted at human food and hydrocolloid markets. However, seaweed biomass also offers a feedstock for the production of nutrient-rich biochar for soil amelioration. We provide the first data of biochar yield and characteristics from intensively cultivated seaweeds (Saccharina, Undaria and Sargassum--brown seaweeds, and Gracilaria, ...

Sargassum is a brown macroalga that has become general environmental problem in the Mexican Caribbean. Despite negative effects on beaches, algae contain compounds of biotechnological and agronomic interest. The possibility using sargassum as substrate under liquid media fermentation (LMF) processes will allow obtention bioactive compounds. In this research, five species from Puerto Morelos reg...
