Introduction: Fucoidan is a sulfated polysaccharide that has a wide range of bioactivities including anti-cancer. This polysaccharide commonly is extracted from marine brown seaweed. There is lack of information on the fucoidan extracted from tropical brown algae and its anti-cancer activity. Objectives: The objectives of this study were to purify fucoidan from Sargassum sp., Turbinaria sp. and Padina sp., and to evaluate their cytotoxicity against breast cancer (MCF-7) and colon cancer cells (WiDr). Materials and Methods: Fucoidan extraction was conducted by using acid extraction method. Purified fucoidans were obtained by DEAE cellulose column chromatography and confirmed by HPLC and FT-IR spectrometry. The cytotoxicity was evaluated by using the MTT (3-[4,5-dimethylthiazol-2-yl] -2,5- diphenyltetrazolium bromide) assay. Results: Fucoidan from Sargassum sp. and Turbinaria sp. showed low cytotoxicity with IC50 ranging between 461-663 μg/mL. Higher cytotoxicity against MCF-7 and WiDr was showed by fucoidan from Padina sp. with IC50 of 144 and 118 μg/mL, respectively. While its IC50 against Vero cells was 501 μg/mL.Standard fucoidan from Fucus vesiculosus exhibited IC50 of 60, 63 and 211 μg/mL against MCF-7, WiDr and Vero Cells, respectively. Although the IC50 was higher than that of standard fucoidan, Padina sp. fucoidan showed cytotoxicity comparable with standard fucoidan at concentrations below 100 μg/mL. Conclusion: These results indicated that Padina sp.fucoidan showed potential selective cytotoxicity, and promising for the development of an anti-cancer compound. © 2016 Phcog.Net.

SUMMARY: Carrageenan extracted from Eucheuma spinosum harvested from three different coastal sea regions, where this alga has been mainly cultivated, were determined for their chemical and physical characteristics. The carrageenan was extracted from the seaweed using hot alkali followed by precipitation, drying, and milling. The carrageenan properties were determined in terms of yield, ash, mineral, sulfate content, functional group, molecular weight, and viscosity profile. Physical characteristics of carrageenan were evaluated by a texture analyzer for gel strength and a rapid visco analyzer for viscosity. The yield of carrageenan from Sumenep (34.81±5.83%) and Takalar (37.16±3.26%) was found to be relatively higher than that of Nusa Penida (25.81±1.93%). The calcium content was higher than magnesium, potassium and sodium content, and no cadmium, lead, mercury, and arsenic detected in all carrageenan. The ash content was around 29%; while, the sulfate content was in the range of 30-32%, and those were not different in all carrageenan. The presence of sulfate content was identified by FTIR at absorption band of 1373cm-1. It was found that the molecular weight of carrageenan from Takalar were relatively higher and the gel strength of carrageenan from Takalar were significantly higher than that of carrageenan from Nusa Penida and Sumenep. Likewise, upon cooling from 80 to 20°C, the viscosity profile of carrageenan from Takalar characterized by higher viscosity compared to that of carrageenan from Sumenep and Nusa Penida. These results indicated that carrageenan from Nusa Penida, Sumenep, and Takalar were identified as iota-carrageenan with similar physico-chemical characteristics except for the gel strength, viscosity profile upon cooling from 80 to 20°C and the yield. © 2017 Japanese Society of Phycology.

A new 3-alkylpiperidine compound (-)-acanthocyclamine A (1) has been obtained from the methanolic extract of Acanthostrongylophora ingens (order Haplosclerida, family Petrosiidae) collected from Wakatobi Marine National Park in South East Sulawesi, Indonesia. The structure of 1 was investigated by extensive 1D-and 2D-NMR experiments. The absolute configuration of 1 was established by X-ray crystallography from anomalous dispersion effects using Cu radiation as C2 (R), C3 (R), C7 (R), and C9 (R). A plausible biosynthetic scheme leading to 1 is presented, and compared with the biosynthetic pathway proposed for the manzamine alkaloids. © 2014 CSIRO.

Marine microorganisms are a rich reservoir of highly diverse and unique biocatalysts that offer potential applications in food, pharmaceutical, fuel, and cosmetic industries. The fact that only less than 1% of microbes in any marine habitats can be cultured under standard laboratory conditions has hampered access to their extraordinary biocatalytic potential. Metagenomics has recently emerged as a powerful and well-established tool to investigate the vast majority of hidden uncultured microbial diversity for the discovery of novel industrially relevant enzymes from different types of environmental samples, such as seawater, marine sediment, and symbiotic microbial consortia. We discuss here in this review about approaches and methods in metagenomics that have been used and can potentially be used to mine commercially useful biocatalysts from uncultured marine microbes.
