Phytomyxea are obligate endoparasites of angiosperm plants and Stramenopiles characterised by a complex life cycle. Here Maullinia braseltonii sp. nov., an obligate parasite infecting the bull kelp Durvillaea (Phaeophyceae, Fucales) from the South-Eastern Pacific (Central Chile and Chiloe Island) and South-Western Atlantic (Falkland Islands, UK) is described. M. braseltonii causes distinct hype...

Herein, Sargassum coreanum (marine algae)-mediated silver nanoparticles (AgNPs) were successfully synthesized by a simple reduction method. The AgNPs characterized using ultraviolet-visible spectroscopy, attenuated total reflection Fourier transformed infrared X-ray diffractometry, field emission scanning electron microscopy (FESEM) with energy-dispersive (EDX) and high-resolution transmission ...

Aqueous and ethanolic extracts obtained from nine Chilean marine macro-algae collected at different seasons were examined in vitro and in vivo for properties that reduce the growth of plant pathogens or decrease the injury severity of plant foliar tissues following pathogen infection. Particular crude aqueous or organic extracts showed effects on the growth of pathogenic bacteria whereas others...

Marine algae are known to contain a wide variety of bioactive compounds, biomaterials derived from marine algae have commercial applications in pharmaceutical, medical, cosmetic, nutraceutical, food and agricultural industries. Marine algae are found to contain high amount of nutrients, vitamins (A, B, C, D & E), minerals (Ca, P, Na & K), antioxidants and dietary fibers, that’s why they are use...

Marine algae are easily produced and are good sources of Fe. If this Fe is bioavailable, algae consumption could help to combat Fe deficiency and anaemia worldwide. The objective of the present study was to evaluate Fe bioavailability, polyphenol content and antioxidant capacity from three species of marine algae distributed worldwide. A total of eighty-three subjects received maize- or wheat-b...

Recently, the studies on the antiviral activities of marine natural products, especially marine polysaccharides, are attracting more and more attention all over the world. Marine-derived polysaccharides and their lower molecular weight oligosaccharide derivatives have been shown to possess a variety of antiviral activities. This paper will review the recent progress in research on the antiviral...

The fucose-containing sulfated polysaccharides (SP) from brown algae exhibit a wide range of bioactivities and are, therefore, considered promising candidates for health-supporting and medicinal applications. A critical issue is their availability in high, reproducible quality. The aim of the present study was to fractionate and characterize the SP extracted from Saccharina latissima (S.l.-SP) ...

The use of a number of species of marine brown algae in the implementation of bioremediation strategies for toxic heavy metals is being considered and evaluated. The biosorption capacity of these algae for heavy metals resides mainly in a group of linear polysaccharides known as alginates that occur as a gel in the algal thallus. The potential for selective metal binding by the biomass of two s...

Nudibranchs are marine gastropods with no shell and usually have a beautiful color pattern. The aim of this work was to record the scyllaeid Crosslandia daedali Poorman & Mulliner 1981 associated brown algae in coastal zone from state Paraíba, northeastern Brazil. One individual species collected November 2019 at about 0.5 meters depth subtidal Cabo Branco Beach city João Pessoa. Immediatel...

Abstract Bacillus coagulans T1.2, an indigenous bacterium from shrimp ponds in East Lampung, has been found to reduce total ammonia nitrogen (TAN). The purpose of this study was know the effectivity immobilization bacterial by sodium alginate marine brown algae wastewater pollution culture. algae, Sargassum sp. and Padina sp., were collected Pesisir Barat Ketapang beach, Lampung. Alginate extra...
