Production and fate of macroalgal carbon in the ocean: How much do macroalgal organics matter?

Limnology and Oceanography Letters, Volume 10, Issue 6, Page 799-814, December 2025.
Abstract Global carbon sequestration by macroalgae is hypothesized to rival rates in other blue carbon ecosystems. However, quantifying macroalgal carbon sequestration is challenging as it is hypothesized to occur outside macroalgal ecosystems, with 73% of sequestration occurring when dissolved organic carbon (DOC) is exported to deep ocean waters.

Slow-Binding Inhibition of Tyrosinase by Ecklonia cava Phlorotannins [PDF]

Marine Drugs, 2019
Tyrosinase inhibitors improve skin whitening by inhibiting the formation of melanin precursors in the skin. The inhibitory activity of seven phlorotannins (1–7), triphlorethol A (1), eckol (2), 2-phloroeckol (3), phlorofucofuroeckol A (4), 2-O-(2,4,6-trihydroxyphenyl)-6,6′-bieckol (5), 6,8′-bieckol (6), and 8,8′-bieckol (7), from Ecklonia cava was ...

Latitudinal variation in the constitutive and inducible defences of a canopy‐forming rocky intertidal seaweed

Functional Ecology, Volume 39, Issue 12, Page 3718-3731, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A long‐standing theory in biogeography is that stronger biotic interactions at lower latitudes select for better‐defended phenotypes. However, greater environmental variability at temperate latitudes may also shape defensive strategies by increasing temporal or local ...

Profiling of the Molecular Weight and Structural Isomer Abundance of Macroalgae-Derived Phlorotannins

Marine Drugs, 2015
Phlorotannins are a group of complex polymers of phloroglucinol (1,3,5-trihydroxybenzene) unique to macroalgae. These phenolic compounds are integral structural components of the cell wall in brown algae, but also play many secondary ecological roles ...

Temperate seaweeds Himanthalia elongata and Fucus vesiculosus significantly reduce rumen methane emissions in vitro due to their high phlorotannin content

Journal of the Science of Food and Agriculture, Volume 105, Issue 13, Page 7522-7534, October 2025.
Abstract BACKGROUND Global food insecurity and the fact that food production contributes around 30% of greenhouse gas (GHG) emissions is a major planetary challenge. Ruminant products are widely consumed since they are macro‐ and micronutrient dense; however, ruminants produce enteric methane (CH4), a potent GHG.
