Macroalgae and Cyanobacteria

2020
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, 2022
Macroalgae 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 ...

Cytokinins in 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, 2015
Sorption 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 ...

Macroalgae

Although there are various routes for the valorisation of macroalgae, the preferential applications are for the food, cosmetic, and pharmaceutical areas, considering the scalability through cultivation, nutritional profile, and presence of bioactive compounds, among other factors, with a focus on specific species that are particularly rich in desired ...

Banded structure of drifting macroalgae

Marine Pollution Bulletin, 2009
A 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, 2013
Macroalgae, 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

Valuable compounds in macroalgae extracts

Food Chemistry, 2013
Bioactive 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,

Cryopreservation of macroalgae

2018
A significant constraint to the development of fundamental and applied research on macroalgae is the capacity to maintain representative cultures of living material ex situ. This is also relevant for their commercial exploitation, where seasonal factors may limit the availability of seed stock for commercial-scale cultivation.
