Extraction and identification of toxic organic substances from decaying green alga Ulva prolifera

Biological activities of secondary metabolites from Turbinaria triquetra (Phaeophyceae), Hypnea cornuta (Florideophyceae), and Ulva prolifera (Ulvophyceae) methanolic extracts

“…Heptadecanes, derived from fatty acids, are one of the principal components of the marine green algae Ulva pertusa and are the signature impact compound of edible kelp (Yamamoto et al, 2014). Similarly, Hexadecanoic acid and 9,12,15octadecatrienoic acid (α-linolenic acid) have been isolated from U. prolifera monomer compounds (Gao et al, 2020). It has been recorded that the brown algae Padina pavonica (Dictyotales) and Hormophysa triquetra (Fucales) contain a high concentration of terpenes and sterols.…”

Ecological Impact Patterns and Temporal Cycles of Green Tide Biomass in the Settlement Region: Based on Time-Series Remote Sensing and In Situ Data

“…Finally, the Chl-a concentration starts to rebound at the decomposition of the green tide. The decay and decomposition of the green macroalgae releases large amounts of nutrients, thereby aggravating the eutrophication of the relevant area [15,69]. At the same time, the disappearance of the green tide will alleviate its inhibitory effect on the phytoplankton, which allows it to recover [34,70] The study area is primarily influenced by the Yellow Sea Coastal Current (YSCC) during the summer season.…”

Inactivation of harmful algal bloom by an environmentally friendly photocatalyst under photo-Fenton-like degradation process

“…According to the literature review (Gao et al, 2020), algal cells contain different macromolecules such as protein, carbohydrates, polypeptides, amino acids, chlorophyll a, DNA, and RNA are supposed to have a complex structure. Therefore, any destruction of the algal cells can lead to the degradation of these macromolecules into leaner and small compounds.…”
