Marine algae, notably , are valuable sources of essential nutrients, including carbohydrates, vitamins, and minerals, as well as bioactive compounds, such as phenols and pigments. In this study, subcritical water extraction of , a brown seaweed, was conducted using a 10% (w/v) seaweed slurry at a temperature of 140°C for 10 min. The concentrations of mannitol, laminarin, and total phenolic content were determined to be 18.93 g/l, 10.79 g/l, and 1.94 mg GAE/g, respectively. The fermented using (SFL) resulted in a maximum biomass production of 4.43 g dcw/l and exhibited an inhibitory activity of 78.69% against pancreatic lipase. The fermented using (SFE) extracts exhibited α-glucosidase inhibitory and antioxidant activities of 59.23% and 65.60%-66.57%, respectively, at a concentration of 3.0 mg/ml. These results facilitate the development of functional seaweed food formulations derived from microbial fermentation.
海藻，尤其是 ，是必需营养素的宝贵来源，包括碳水化合物、维生素和矿物质，以及生物活性化合物，如酚类和色素。在本研究中，使用10%（w/v）的海藻浆液在140°C的温度下对褐藻 进行亚临界水提取10分钟。测定甘露醇、海带多糖和总酚含量的浓度分别为18.93 g/l、10.79 g/l和1.94 mg GAE/g。使用 （SFL）发酵 产生的最大生物量产量为4.43 g dcw/l，对胰脂肪酶的抑制活性为78.69%。使用 （SFE）提取物发酵的 在浓度为3.0 mg/ml时，α-葡萄糖苷酶抑制活性和抗氧化活性分别为59.23%和65.60%-66.57%。这些结果有助于开发源自微生物发酵的功能性海藻食品配方。
