Current Trends on Seaweeds: Looking at Chemical Composition, Phytopharmacology, and Cosmetic Applications

Molecules, Journal Year: 2019, Volume and Issue: 24(22), P. 4182 - 4182

Published: Nov. 18, 2019

Seaweeds have received huge interest in recent years given their promising potentialities. Their antioxidant, anti-inflammatory, antitumor, hypolipemic, and anticoagulant effects are among the most renowned studied bioactivities so far, these been increasingly associated with content richness both primary secondary metabolites. Although metabolites a pivotal importance such as polysaccharides (fucoidans, agars, carragenans, ulvans, alginates, laminarin), data shown that some largely determines effective bioactive potential of seaweeds. Among metabolites, phenolic compounds feature prominently. The present review provides remarkable insights into seaweed research, specifically addressing its chemical composition, phytopharmacology, cosmetic applications.

Ecological Role of Submarine Canyons and Need for Canyon Conservation: A Review

Frontiers in Marine Science, Journal Year: 2017, Volume and Issue: 4

Published: Jan. 31, 2017

Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on study have considerably increased our understanding their ecological role, goods and services they provide to human populations, impacts that activities overall condition. Pressures from include fishing, dumping land-based mine tailings, oil gas extraction. Moreover, hydrodynamic processes enhance down-canyon transport litter. The effects climate change may modify intensity currents. This potential hydrographic is predicted impact structure functioning canyon communities as well affect nutrient supply deep-ocean ecosystem. review not only identifies status canyons, current future issues for conservation, but also highlights need a better anthropogenic ecosystems proposes other research required inform management measures protect ecosystems.

Effects of Marine and Freshwater Macroalgae on In Vitro Total Gas and Methane Production

PLoS ONE, Journal Year: 2014, Volume and Issue: 9(1), P. e85289 - e85289

Published: Jan. 22, 2014

This study aimed to evaluate the effects of twenty species tropical macroalgae on in vitro fermentation parameters, total gas production (TGP) and methane (CH4) when incubated rumen fluid from cattle fed a low quality roughage diet. Primary biochemical parameters were characterized included proximate, elemental, fatty acid (FAME) analysis. Macroalgae control, decorticated cottonseed meal (DCS), for 72 h, where was continuously monitored. Post-fermentation including CH4 production, pH, ammonia, apparent organic matter degradability (OMd), volatile (VFA) concentrations measured. All had lower TGP than DCS. Dictyota Asparagopsis strongest effects, inhibiting by 53.2% 61.8%, 92.2% 98.9% after respectively. Both also resulted lowest VFA concentration, highest molar concentration propionate among all analysed, indicating that anaerobic affected. Overall, there no strong relationships between or >70 analysed. However, zinc >0.10 g.kg−1 may potentially interact with other components influence production. The lack relationship primary biochemistry suggests significant decreases are associated secondary metabolites produced effective macroalgae. most species, Asparagopsis, offers promising alternative mitigation enteric emissions.

Alternative and Efficient Extraction Methods for Marine-Derived Compounds

Marine Drugs, Journal Year: 2015, Volume and Issue: 13(5), P. 3182 - 3230

Published: May 21, 2015

Marine ecosystems cover more than 70% of the globe’s surface. These habitats are occupied by a great diversity marine organisms that produce highly structural diverse metabolites as defense mechanism. In last decades, these have been extracted and isolated in order to test them different bioassays assess their potential fight human diseases. Since traditional extraction techniques both solvent- time-consuming, this review emphasizes alternative techniques, such supercritical fluid extraction, pressurized solvent microwave-assisted ultrasound-assisted pulsed electric field-assisted enzyme-assisted with switchable solvents ionic liquids, applied search for compounds.
