BACKGROUND Gracilaria changii (Xia et Abbott) Abbott, Zhang et Xia, a red algae commonly found in the coastal areas of Malaysia is traditionally used for foods and for the treatment of various ailments including inflammation and gastric ailments. The aim of the study was to investigate anti-inflammatory, gastroprotective and anti-ulcerogenic activities of a mass spectrometry standardized methan...

The fronds of marine macroalgae play an important role in coastal ecosystems because the algae banks are utilized as a microhabitat by different taxa, including molluscs, one of the most abundant and diverse animals of marine ecosystems. In this study, we characterized the malacofauna associated with the macroalgae Gracilaria domingensis (Kützing) Sonder ex Dickie 1874 and Gracilaria cuneata Ar...

The likelihood of invasion success increases when non-native species engage in mutualisms with a native or non-native species. Mutualisms formed between native and nonnative species have been termed ’novel mutualisms’, and research in terrestrial systems has advanced our understanding of the ecological processes involved in their formation and persistence. However, documentation of novel mutual...

The aim of the present study was to investigate the gastroprotective activity of a sulfated-polysaccharide (PLS) fraction extracted from the marine red algae Gracilaria caudata and the mechanism underlying the gastroprotective activity. Male Swiss mice were treated with PLS (3, 10, 30 and 90 mg·kg(-1), p.o.), and after 30 min, they were administered 50% ethanol (0.5 mL/25 g(-1), p.o.). One hour...

Abstract Activated carbon obtained from red algae Gracilaria changii was used as an adsorbent to remove Pb (II) and Cu aqueous solution. The raw were first impregnated with phosphoric acid, followed by thermal activation. Box–Behnken design optimize the activation process. optimum parameters 84%, 650 °C, 175 min for acid concentration, temperature, time, respectively. activated had a high surfa...

Eutrophication has become a serious environmental problem because of the excessive amounts nitrogen and phosphorus in water. Aquaculture waste is one drivers eutrophication. Seaweed known for its ability to remove nutrients from In Indonesia, research about efficiency seaweed decreasing nutrient concentration wastewater still rare. This article reviewed use as an adsorbent removal. review aims ...
