Four sterols were isolated from a brown alga endophytic fungus NO. ZZF36 from the South China Sea. Their structures were identified as brassicaterol(2), ergosterol(2), ergosterol peroxide(3),7,22(E)-ergostadiene-beta,5alpha,6beta-triol(4) by spectroscopic methods.

is an invasive brown macroalga that has recently proliferated in the western Mediterranean Sea, causing significant environmental challenges. This alga, however, contains valuable bioactive compounds-alginate, mannitol, and phlorotannins-that can serve as biofertilizers to promote plant growth and aid in bioremediation of degraded or contaminated soils. This study focused on optimizing the extraction of these compounds from , transforming an ecological issue into a beneficial resource.

The brown alga (SF) is historically consumed as a food material in Japan. A steaming process is often required for SF products on the market due to their moderate hardness and astringent taste. This investigation aimed to elucidate the effect of steaming on the anti-diabetic activity of SF and its related chemical components.

Since 2011, massive strandings of Sargassum (brown alga) have significantly affected Caribbean islands causing major health, environmental and economic problems. Amongst them, the degradation of algae releases corrosive gases, hydrogen sulphide (HS) and ammonia (NH) which causes an accelerated corrosion of the metallic structures of these coastal areas. The aim of this study was to quantify the impact of Sargassum strandings on the corrosion of three types of steels (DC01 carbon steel, 304L and 316L stainless steels) immersed for up to 120 days at various sites in Martinique which were gradually impacted by Sargassum.

Cisplatin is a chemotherapeutic drug, which exhibits undesirable side effects. Chitosan nanoparticles are promising for drug delivery. The aim of this study was to determine the effect of the brown alga Turbinaria triquetra ethyl acetate fraction and polysaccharides, either loaded on chitosan nanoparticles or free, against podocyturia and cisplatin nephrotoxicity in rats.

Reproduction, development and homeostasis depend on motile cilia, whose rhythmic beating is powered by a microtubule-based molecular machine called the axoneme. Although an atomic model of the axoneme is available for the alga Chlamydomonas reinhardtii, structures of mammalian axonemes are incomplete. Furthermore, we do not fully understand how molecular structures of axonemes vary across motile-ciliated cell types in the body.
