Data on the chemical composition of 40 edible red algal species was compared to Grateloupia gibbesii, a recently reported non-indigenous red alga in the Mediterranean Sea. There has been no information on the seasonality or the chemical composition of G. gibbesii from its areas of distribution. The species was reported in a single location in the Mediterranean Sea, a eutrophic embayment in Egypt. Grateloupia gibbesii existed in spring from late March to early June. The short life span of G. gibbesii affected its biochemical constituents. Crude lipids and total carbohydrate contents represented 12 % and 70% of its dry mass; resp. Five grams of dry G. gibbesii could provide 8.6% and 91% of the recommended dietary intake of lipids and carbohydrates. In contrast, protein and ash contents were low in comparison to other red seaweeds. The analysis of mineral content showed that Ca, Fe and Zn concentrations were high, while Cd and total As, might be at a toxic level. In Egypt, exploitation of seaweeds is still emerging; accordingly, more studies are needed to assess the application of seaweeds as a healthy and renewable alternative in the nutraceutical, cosmetics, and well-being industries.

将有关40种可食用红藻物种化学成分的数据与最近报道的地中海非本地红藻Grateloupia gibbesii进行了比较。从其分布区域，没有关于吉氏短吻菌的季节性或化学成分的信息。据报道该物种位于地中海的一个地方，埃及是一个富营养化的巢穴。3月下旬至6月初存在于春季的Grateloupia gibbesii。Gibbesii的短寿命影响了它的生化成分。粗脂肪和总碳水化合物含量分别占其干重的12％和70％；分别 五克干的吉氏白僵菌可以提供建议饮食中脂质和碳水化合物摄入量的8.6％和91％。相反，与其他红海藻相比，蛋白质和灰分含量较低。矿物质含量分析表明，Ca，Fe和Zn浓度较高，而Cd和总As可能处于有毒水平。在埃及，对海藻的开采仍在兴起。因此，需要更多的研究来评估海藻作为保健食品，化妆品和福利行业中健康和可再生替代品的应用。
