Kappa carrageenan is an important phycocolloid extracted from the red seaweed Kappaphycus alvarezii. This species has been introduced into several regions, most recently in Brazil. The remote invasive potential of this seaweed in both south and southeast waters of Brazil (subtropical regions) has been established, but introduction in the northeastern tropical area is contested due to the absenc...

In this study, a simple, rapid, and eco-friendly green method was introduced to synthesize magnetite nanoparticles (Fe3O4-NPs) successfully. Seaweed Kappaphycus alvarezii (K. alvarezii) was employed as a green reducing and stabilizing agents. The synthesized Fe3O4-NPs were characterized with X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FT-IR), ...

A pot experiment was conducted in rabi season 2004-05 to study the effect of Kappaphycus alvarezii extract applied as a foliar spray at 0.25%, 0.50% and 1.0% on wheat. Compared to control the yield of grain increased by 80.44% when, the plants were sprayed with 1.0% K. alvarezii extract. The nutritional quality of grain such as carbohydrate, protein and minerals also improved under the influenc...

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...

This study investigates the effect of salt reduction through inclusion seaweed (Kappaphycus alvarezii) on physicochemical and sensory qualities chicken patties. A control sample (1.5% without seaweed) four patty formulations were used with two levels (1% 1.5%) (2% 4%). Adding improves water holding capacity minimized cooking loss in reduced-salt In addition, adding decreases shrinkage diameter ...

This study investigated the potential of seaweed extract Kappaphycus alvarezii as biostimulant in 3% concentration on relative growth rate, net assimilation and root to shoot ratio mangrove propagules Rhizophora mangle L. through different day- intervals foliar application under field experiment. There were two factors included: factor A- types treatment (A1- water, A2- extract, A3- commercial ...

Alginate impression material is important in dentistry. In its clinical application, setting time still considered too fast, and the alginate must have dimensional stability accordance with ANSI / ADA standard specification no.18. has a main component, namely sodium which produced from seaweed extraction process. Indonesia, there are several types of seaweed, one Kappaphycus alvarezii (K. alvar...

The two red seaweeds, Gracilaria manilaensis and Kappaphycus alvarezii are cultivated in Malaysia for producing agar and carrageenan, respectively. The residues of these seaweeds after removing agar and carrageenan by dilute acid treatment were subjected to enzymatic hydrolysis using cellulase (Cellic CTec 2). In the optimization of enzymatic hydrolysis, highest glucose concentration was achiev...

In the search for bioactive compounds, 11 fungal strains were isolated from Indonesian marine habitats. Ethyl acetate extracts of their culture broth were tested for cytotoxic activity against a urinary bladder carcinoma cell line and for antifungal and antibacterial activities against fish and human pathogenic bacteria as well as against plant and human pathogenic fungi. The crude extract of a...
