A Study on the Antimicrobial Activity of Algae Extract: The Fucales Order Case

Biology and Life Sciences Forum
Over the years, foodborne pathogens have caused countess health problems and massive financial losses. Therefore, an essential goal for the food industry is to prevent food contamination and the related foodborne illnesses as microbial contamination of ...

Significant changes in seaweed community structure revealed by a nationwide long‐term monitoring survey in Japan ‘Monitoring‐Site 1000’ over the past 15 years (2008–2022)

Phycological Research, Volume 74, Issue 1, Page 39-56, January 2026.
SUMMARY Significant changes in seaweed communities were identified at six sites in Japan through the long‐term monitoring program ‘Monitoring Sites 1000.’ This study summarizes the results of 15 years of surveys conducted from 2008 to 2022. Annual nondestructive permanent quadrat observations and line‐transect surveys, carried out perpendicular to the ...

Warming seas: Native Sargassum species at risk

Limnology and Oceanography, Volume 70, Issue 12, Page 3561-3575, December 2025.
Abstract Sargassum species play a critical role in tropical and temperate coastal ecosystems by contributing to primary production and providing habitat to different species, while causing ecological disruptions and social challenges in some localities.

Diversified Chemical Structures and Bioactivities of the Chemical Constituents Found in the Brown Algae Family Sargassaceae

Marine Drugs
Sargassaceae, the most abundant family in Fucales, was recently formed through the merging of the two former families Sargassaceae and Cystoseiraceae. It is widely distributed in the world’s oceans, notably in tropical coastal regions, with the exception

Opportunistic Macroalgae as a Component in Assessment of Eutrophication

Diversity, 2022
For the last few decades, coastal eutrophication with the associated mass development of opportunistic macroalgae has increased on a global scale. Since the end of the 2000’s, the number of studies of macroalgal blooms also increased many times.

Review of available DNA sequence data: our understanding of macroalgal diversity in New Zealand

New Zealand Journal of Botany, Volume 63, Issue 5, Page 2264-2274, December 2025.
ABSTRACT Understanding our biodiversity is of the utmost importance to determine evolutionary histories of organisms, reliably detect new incursions and select species for commercial operations. Advances in molecular techniques have provided a strong tool to facilitate a deeper understanding of our biodiversity. Macroalgae are a polyphyletic group that

Interspecific variation in total phenolic content in temperate brown algae

Journal of Biological Research, 2017
Marine algae synthesize secondary metabolites such as polyphenols that function as defense and protection mechanisms. Among brown algae, Fucales and Dictyotales (Phaeophyceae) contain the highest levels of phenolic compounds, mainly phlorotannins, that ...

The role of the epidermal physode layer in UV protection of Fucus species

Journal of Photochemistry and Photobiology, 2023
Phlorotannins are believed to provide UV protection in brown algae. In Fucus species, phlorotannin-rich vesicles (“physodes”) form an “epidermal physode layer”, which might represent the anatomical structure responsible for UV protection.

An Acetocarmine Squash Technique for the Fucales [PDF]

Nature, 1957
ACETOCARMINE techniques have only been used to a limited extent in cytological studies of the Phaeophyta, and only in examination of filamentous forms, or filamentous phases in the life-history of the larger forms. Investigations of the Fucales have relied on techniques of embedding and microtoming, followed by staining with Heidenhain's haematoxylin1 ...
