Abstract

More than 3000 MT of Sargassum illicifolium ,annually washed-up from the Oman Sea (Sistan and Baluchestan province). , According to the estimates of the Iranian Fisheries Sciences Researchinstitiute.The brown seaweed biomass has been considered as one of the best free sources for production of sodium alginate. A key objective of this study was to determine the biochemical composition of Sargassum illicifolium collected from Chabahar Bay in November 2018and to understand the economic potential and cost drivers of sodium alginate on basis of the present macroalgae. Alginates were purified by re-precipitation with ethanol and characterized by infrared spectroscopy. The results showed that the Chabahar Sargassum was characterized by total protein (TP), total lipid (TL) and carbohydrate as 9.8±0.8%, 4.4±0.2% and 33.2±4.1% dry weight, respectively. The ash content contained 41.6±2.3% DW. Moreover, the n-6/n-3 ratio was 2.62 and total essential amino acids and total minerals were 29.1±0.2 mg g-1 DW and 102. 2±0.6 mg g-1 DW, respectively. sodium alginate of Sargassum illicifolium was found to be high as 28.2% purification with molecular weight of 8.06×105 g mol-1. Its total production price was evaluated 7.66 $ per kg sodium alginate, which is much cheaper than existing ones on the Iranian market.

伊朗阿曼湾Chabahar湾褐藻Sargassum illicifolium (Turner) C. Agardh, 1820的生化组成及生产海藻酸钠的经济可行性研究

每年从阿曼海（锡斯坦省和俾路支斯坦省）冲上来的非法马尾藻超过3000公吨，根据伊朗渔业科学研究所的估计，褐藻生物量被认为是生产藻酸钠的最佳自由来源之一。本研究的一个关键目标是确定2018年11月从Chabahar湾采集的泥鳅的生化成分，并在现有大型藻类的基础上了解藻酸钠的经济潜力和成本驱动因素。通过用乙醇再沉淀纯化藻酸盐，并通过红外光谱进行表征。结果表明，马尾藻的总蛋白质（TP）、总脂质（TL）和碳水化合物含量分别为干重的9.8±0.8%、4.4±0.2%和33.2±4.1%。灰分含量为41.6±2.3%DW。此外，n-6/n-3的比例为2.62，必需氨基酸和矿物质的总量分别为29.1±0.2 mg g-1 DW和102。分别为2±0.6 mg g-1 DW。泥鳅藻酸钠的纯化率高达28.2%，分子量为8.06×。它的总生产价格为每公斤7.66美元，比伊朗市场上现有的价格便宜得多。
