Abstract Fucoxanthin, a natural xanthophyll carotenoid, is generally found in brown seaweeds, such as Sargassum duplicatum, Turbinaria turbinata, Padina australis, Undaria pinnatifida, and Laminaria japonica; microalga or diatom Phaeodactylum tricornutum, Isochrysis galbana Odontella sinensis. Fucoxanthin marine exhibiting several anticancer activities, activities against leukemia, prostate, ce...

Selective macroalgae comprising green algae (Ulva lactuca), brown (Padina gymnosphora, Sargassam wightii, Turbinaria ornate) and red (Gracilaria corticata, Halimeda macrolopa, Halymenia dilatata, Gracilaria crassa) were collected from Gulf of Mannar, India. Taxonomic molecular identification affirmed the identity microalgal species. Free fatty acids Fatty Acid Methyl Ester (FAME) synthesis by t...

BACKGROUND AND OBJECTIVES Sixty ethanol extracts of marine flora of Baja California Sur (Mexico) were screened to evaluate the reversing effect of the bacterial resistance to antibiotics in combination with a sublethal concentration of ampicillin or erythromycin. MATERIALS AND METHODS The activity was assayed by using a modification of the classical agar-diffusion method against 3 resistant, ...

The endophytic fungus Fusarium equiseti was isolated from the brown alga Padina pavonica, collected from the Red Sea. The fungus was identified by its morphology and 18S rDNA. Cultivation of this fungal strain in biomalt-peptone medium led to isolation of 12 known metabolites of diketopeprazines and anthraquinones. The organic extract and isolated compounds were screened for their inhibition of...

The aim of this study is to adopt the approach of metabolic fingerprinting through the use of Fourier Transform Infrared (FTIR) technique to understand changes in the chemical structure in Padina tetrastromatica (Hauck). The marine brown alga under study was grown in two different environmental conditions; in natural seawater (P. tetrastromatica (c)) and in seawater suplemented with 50 ppm of c...

Sulfated polysaccharides have shown promising effects on wound healing processes along with many other biological activities. The sulfated polysaccharides extracted from two algae species habitats in Persian Gulf were studied in vivo for their effects on collagen formation and epidermal regeneration. The polysaccharides were purified from aqueous extracts of P. tetrastromatica and P. boergeseni...
