- Abstract:
- ... Ultrasound assisted aqueous extraction of alginate from Sargassum muticum was proposed to minimize the use of chemicals, high temperatures and prolonged times, with comparable extraction yields to conventional acid/alkali procedures. The alginate, precipitated from the liquors obtained after ultrasound assisted extraction of fucoidan and phlorotannin fractions, and converted to alginic acid sodium ...

- Abstract:
- ... Sargassum muticum is an invasive brown seaweed that causes a negative impact on ecology, fishing and recreational activities, and was also associated with changes in biodiversity by competing for light, space and nutrients with autochthonous algae. Marine brown seaweeds contain different valuable components, such as alginate, fucose rich sulfated polysaccharides (known as fucoidans) and phlorotann ...

Therefore, it is necessary to consider these impacts when managing marine areas. One of the most applied tools in recent years to deal with this are species distribution models, however there are still some challenges to solve, such as the inclusion of hydrodynamic predictors and ...

- Abstract:
- ... Sargassum muticum is an invasive brown seaweed which could not be eradicated from the Atlantic coasts. Therefore, periodic collection and valorization of its components has been suggested. Efficient multistage and multiproduct processes for the obtaining of valuable fractions from this seaweed, which also could be applicable to other brown seaweeds, were developed. This review discusses the potent ...

Temperature and day length are known environmental drivers of the reproductive timing of many species. Hence, reproductive phenology is sensitive to warming and is important to be considered for reliable predictions of s ...

Populations of the invasive alga Sargassum muticum were sampled along a time-since-invasion (TSI) gradient to test the hypothesis that chemical defences would increase with TSI, and diversity of native mesoherbivores. Algal chemical defences, phlorotannins, were quantified as a proxy for top-down-pressure, and these were compared with both native enemy diversity and time-since-invasion at each of ...

There is considerable conjecture about the reasons for the relatively low practical methane yields from seaweed, and polyphenols are suggested as one of the elements in the low yield of methane from brown seaweeds. However, there appears to be ...
