Construction of Remediation Eco-system Using Green Algae Grown under High CO_2 Conditions - Application of High Efficient System Utilized Sun-light -

纤细裸藻（Euglena gracilis）在植物界被分类为绿色藻类，在动物界被分类为原生动物。这种生物是一种光合作用的单细胞真核生物，大约30亿年前出现在地球上。该菌能在2 ~ 5的pH范围内生长，即使在高浓度CO_2（20 ~ 40%）下也能生长。纤细裸藻（Euglena gracilis）是一种细长的藻体，长约20 ~ 50 μ m，宽约为藻体长度的1/5。裸藻通过改变身体的形状，可以沿着鞭毛运动。食物或营养物质直接通过细胞表面吸收。纤细裸藻能在添加维生素B_1和B_的轻无机培养基中生长<12>。在黑暗中，需要有机能源。纤细裸藻可作为测定生物材料和天然水中B_的检测生物<12>。纤细裸藻（Euglena gracilis）的种群数量（如绿色花朵）在环境温度升高时会急剧增加。 关于我们 还已知收获的裸藻细胞可用于生产工业材料如蜡酯、角鲨烯和烃，或生产含有各种维生素、多不饱和脂肪酸和抗高血压剂的双功能食品。裸藻富含蛋白质。氨基酸评分和净蛋白质利用率分别为88和79.9，高于其他单细胞生物如小球藻或螺旋藻。裸藻的营养成分与牛奶酪蛋白相似。甘油三酯主要由不饱和脂肪酸组成，尤其是亚油酸是人类必需的脂肪酸，裸藻在自养生长时还含有大量的花生四烯酸。由该生物合成的副淀粉具有裸藻特有的β-1.3-葡聚糖和海藻糖，海藻糖也是人类可利用的营养素。营养素，维生素通过暴露在强烈的光照下或通过添加一些前体而变得非常丰富。这些观察结果表明，裸藻细胞作为封闭生态系统中的唯一营养物是有用的。事实上，在月球基地的封闭环境生命支持系统中，纤细裸藻作为人类的营养物质已经被研究了很长一段时间。少

Euglena gracilis is classified both as green algae in the plant kingdom and as protozoa in the animal kingdom. This organism is a photosynthetic unicellular eukaryote and it appeared in the earth some 3 billion years ago. This organism can grow at 2〜5 pH ranges even under high concentration CO_2(20〜40%) in the atmosphere. Therefore, Euglena can be used in reducing CO_2 in the atmosphere.Euglena gracilis has an elongated body of 20〜50 microns in length and the width is 1/5 of the length. By changing the shape of the body, Euglena can move along with flagellum. Foods, or nutrients are absorbed directly through the cell surface. Euglena gracilis can grow in light inorganic media supplemented with vitamin B_1 and B_<12>. In darkness, an organic energy source is required. Euglena gracilis can be used as an assay organism for determining the presence of B_<12> in biological materials and natural water. The population of Euglena gracilis(as green blooms) can increase tremendously when the env … More ironment is suitable.It is also known that harvested Euglena cells can be utilized for the production of industrial materials like wax esters, squalene and hydrocarbons, or of bifunctional foods containing various vitamins, polyunsaturated fatty acids and antihypertensive agents. Euglena is rich in proteins. The amino acid score and net protein utilization are 88 and 79.9, respectively, higher than those of other single cell organisms such as Chlorella or Spirulina. The nutrients of Euglena are similar to cow-milk casein. Triglycerides are mainly composed of unsaturated fatty acids, especially linoleic acid which are essential fatty acids for mankind, and also contains considerable arachidonic acid when Euglena is grown autotrophically. Paramylon systhesized by the organism has the characteristic β-1.3-glucan in Euglena, and trehalose which is also available for mankind as a nutrient. Micronutrients, vitamins become extremely rich by being exposed to strong illumination or by adding some precursors. These observations show that Euglena cells are useful as sole nutrients in a closed ecosystem. In fact, Euglena gracilis has been studied for a long period as the nutrients for mankind in a closed environmental life support system on the lunar base. Less
