Ethanolic crude extracts from seven marine algal species belong to Clorophyceae (Cladophora glomerata, Enteromorpha linza, Ulva rigida), Phaeophyceae (Cystoseira barbata, Padina pavonica) and Rhodophyceae (Corallina officinalis, Ceramium ciliatum) from the coast of Vona, Turkey were evaluated in vitro for the antibacterial and antifungal activity of six bacteria and two fungus with the paper di...

Climate change is a global phenomenon that is considered an important threat to marine ecosystems. Ocean acidification and increased seawater temperatures are among the consequences of this phenomenon. The comprehension of the effects of these alterations on marine organisms, in particular on calcified macroalgae, is still modest despite its great importance. There are evidences that macroalgae...

—Padina antillarum (Kützing) Piccone and P. glabra Gaillard are newly reported for Florida. The first species, which has been widely reported from the Indo-Pacific under the name P. tetrastromatica Hauck, has seldom been reported from the Western Atlantic. The type locality of P. antillarum is Trinidad in the Lesser Antilles, and there are reports of its occurrence from Venezuela and Colombia. ...

Padina sanctae-crucis Børgesen is distributed worldwide in tropical and subtropical seas; belongs to the Dictyotaceae family, and has proven to be an exceptional source of biologically active compounds. Four compounds were isolated and identified, namely: dolastane diterpene new for the genus Padina; phaeophytin and hidroxy-phaeophytin new for the family Dictyotaceae, and; mannitol first descri...

Background: Padina sp. is an algae that has potential as a functional food. This study aimed to explore the chemical and photochemical constituent in the methanolic exract of Padina sp. Methods: Brown algae of Padina sp. from Puntondo coast, Takalar, Indonesia was prepared. The algae characterization was carried out based on the standard procedure of Association of Official Agricultural Chemis...

Article history: Received on: 03/04/2016 Revised on: 05/05/2016 Accepted on: 30/06/2016 Available online: 26/09/2016 Marine algae are potential sources of biologically active compounds with antiviral, antimicrobial and anticancer activities. Two species of marine algae, Padina boryana Thivy and Enteromorpha sp were collected from the Red Sea. Both species were extracted with ethanol, acetone, a...

Predicting the impacts of ocean acidification on coastal ecosystems requires an understanding of the effects on macroalgae and their grazers, as these underpin the ecology of rocky shores. Whilst calcified coralline algae (Rhodophyta) appear to be especially vulnerable to ocean acidification, there is a lack of information concerning calcified brown algae (Phaeophyta), which are not obligate ca...

Abstiact: When offered single species of seaweeds in excess amounts, the sea urchin Arbuciapunctulata (Lamarck) Philippi consumed significantly more Gracilana folijr,a (Forsskal) Borgrsen and Codium z3thmocladium Vickers than Sargassum filipendula C. Agardh, Padina vickersiae Hoyt, or Dictyota dichotomu (Hudson) Lamouroux. When all five species were offered to urchins simultaneously, patterns o...

BACKGROUND Multi-resistantmicroorganisms such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida tropicalis e Candida krusei are the main causes of microbial infections. Padina sanctae-crucis is a seaweed often used to check the contamination of ecosystems by materials such as heavy metals, but studies of the antimicrobial activity of the same seaweed were not found. ...
