Ecophysiology of photosynthesis in macroalgae
Photosynthesis Research, 2012Macroalgae occur in the marine benthos from the upper intertidal to depths of more than 200 m, contributing up to 1 Pg C per year to global primary productivity. Freshwater macroalgae are mainly green (Chlorophyta) with some red (Rhodophyta) and a small contribution of brown (Phaeophyceae) algae, while in the ocean all three higher taxa are important ...

Macroalgae (fleshy and calcareous seaweeds), along with sponges, stony and soft corals, hydroids, bryozoans, and tube-building polychaete worms are the critical building blocks of biological habitats of nearshore hardbottom reefs of east Florida. Physical characteristics of these foundation species enhance available shelter for fish and invertebrates ...

Plastic debris in coastal macroalgae
Environmental Research, 2022Macroalgae are the most productive marine macrophytes in the coastal ecosystem. Although plastic debris has been ubiquitously detected in marine animals, little is known about plastic pollution in macroalgae and how they interact with each other. In this study, the occurrence of plastic debris including microplastics was investigated in 5 macroalgae ...

Plant Growth Regulation, 2003
Thirty-one seaweeds were collected from the warmer KwaZulu-Natal coast and the cooler Cape waters (South Africa). Plant material was extracted with 70% ethanol supplemented with deuterium labelled standards of all known isoprenoid cytokinins.

Biosorption of cadmium with brown macroalgae
Chemosphere, 2015Sorption experiments for cadmium removal using two brown macroalgae Lessonia nigrescens and Durvillaea antarctica were carried out. Although both types of algae were capable of retaining cadmium, differences in their performance were observed. The optimum pH was 3.7±0.2, and to achieve the equilibrium, 5 days of contact time were necessary for both ...

Banded structure of drifting macroalgae
Marine Pollution Bulletin, 2009A massive bloom of macroalgae occurred in the western Yellow Sea at the end of May, 2008, and lasted for nearly 2 months. The surface-drifting macroalgae was observed to accumulate in a pattern dominated by linear bands. The maximum length of individual algal bands exceeded 10 km and the distance between neighboring bands ranged from hundreds of meters

Potentials of macroalgae as feedstocks for biorefinery
Bioresource Technology, 2013Macroalgae, so-called seaweeds, have recently attracted attention as a possible feedstock for biorefinery. Since macroalgae contain various carbohydrates (which are distinctively different from those of terrestrial biomasses), thorough assessments of macroalgae-based refinery are essential to determine whether applying terrestrial-based technologies to

The steep rise in human population together with the simultaneous growth of urbanization and industrialization has triggered overuse of fossil fuels in the recent years. However, they are non-renewable and release carbon dioxide causing global warming.

Valuable compounds in macroalgae extracts
Food Chemistry, 2013Bioactive compounds present in ethanolic extracts from 18 macroalgae of the Portuguese coast were analysed by gas chromatography-mass spectrometry (GC-MS), leading to the characterization of 14 compounds: proline, phloroglucinol, mannitol, 8 fatty acids and 3 sterols. A dose-dependent response against enzymes with biological significance (α-glucosidase,
