“…Other studies made with this species concern the influence of the farming on the surrounding biota, biofouling processes in sea cultivation, micropropagation cultures, biofilter potential, analysis of cell biology and the influence of environmental factors on the growth and carrageenan production (Pellizzari & Reis, 2011). The interaction with a biostimulant of algal growth has being studied (Loureiro et al, 2011) and investigations to verify cosmetic and pharmacological potential are beginning (unpublished data).…”

Kappaphycus alvarezii (Rhodophyta, Gigartinales) is a red algae widely cultivated as the main source of raw material for the carrageenan industry. This hydrocolloid is normally used in the food industry as a gelling and stabilizing agent. The facility of its commercial farming based on vegetative propagation promoted the success of the aquaculture of this macroalgae that consequently stimulated studies focusing on new potential uses of this resource. This work presents a brief review of the studies related to K. alvarezii cultivation in southern and southeastern Brazil, the latest discoveries in the world concerning pharmacological studies with this species and the advantages of the use of carrageenan as a source of dietary fiber, cholesterol reducer, and antioxidant, anti-viral and anti-cancer compounds, as well as the effects in hemagglutination activity.

“…16 Despite the large number of brown algae species found along the Brazilian coast, there is no effective exploration for alginate extraction and commercialization. 17,18 On the other hand, the alginate extraction residue has been introduced as biosorbent for toxic metals removal in batch mode, due to its binding sites that are similar to raw algae. [19][20][21][22] However, considering the large volume of wastewater and the high flow rate, the batch biosorption process may not be suitable for large-scale application.…”

BACKGROUND The alginate extraction residue from Brazilian Sargassum filipendula was employed as biosorbent for Zn(II) removal through a fixed‐bed column in order to explore its adsorptive properties and to establish a new use for this waste. RESULTS The best operating conditions were 0.5 mL min‐1 and 1.0 mmol L‐1 (inlet concentration), providing lower mass transfer zone and higher uptake. Elution percentages of 52 and 73% were obtained for the first and second desorption cycles, respectively, using CaCl2 as eluent. The Yan et al. model was more representative of the experimental data. Characterization revealed that ion exchange is involved between zinc ions and light metals (Ca, Na, K and Mg). A decrease was observed in real and apparent densities of biomass, with an increase in particle porosity of the residue after process. CONCLUSION The study revealed that this biomass has potential for Zn removal from aqueous solution, encouraging its application as a biosorbent in future studies involving multicomponent systems. © 2017 Society of Chemical Industry

Despite the potential for harvesting in the southeastern areas, the importance of cultivation to avoid depleting this resource has been emphasized (Faccini & Berchez 2000;Reis et al 2008).…”

Hypnea musciformis: alternative or complement to the production ofKappaphycus alvareziiintroduced in tropical countries?

et al. 2015

Hypnea musciformis that are harvested from natural beds and introduced Kappaphycus alvarezii are the two main sources of raw material for the production of carrageenan in Brazil. The daily growth rate (DGR) and carrageenan yield (CY) of both species were evaluated in vitro and in the sea to assess the feasibility of cultivating H. musciformis as a complement or as an alternative to the production of K. alvarezii. The DGR of H. musciformis (10.8 ± 0.6% day−1) was higher than the DGR of K. alvarezii (5.6 ± 0.3% day−1) in vitro, and the CY extracted using NaOH (62.3 ± 0.15%) was better than using KOH (32.0 ± 0.3%). In eutrophic medium, the DGR of H. musciformis (9.4 ± 2.1% day−1) was higher than that of K. alvarezii (5.0 ± 1.2% day−1). However, in this condition, the CY was similar for both species (50.2 ± 3.5%), and both species were effective in removing nutrients (30% NH4+, 18% NO2− and 2.4% PO43−). H. musciformis did not survive when cultivated in the sea, neither in monospecific nor in multispecific cultivation. Moreover, K. alvarezii grew better in monospecific cultivation throughout the year (from 1.73 to 5.15% day−1) except during the wet period and the CY was high in both cultivation types (33.7–50.8%). We conclude that the cultivation of H. musciformis is not an alternative to K. alvarezii on the Brazilian southeastern coast. However, the results in vitro suggested its use as a complementary source of carrageenan or as a biological filter.
