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

绿藻在植物界被归类为绿藻，在动物界被归类为原生动物。这种生物是一种光合作用的单细胞真核生物，大约在30亿年前出现在地球上。即使在大气中高浓度CO_2（20 ~ 40%）的条件下，该生物也能在2 ~ 5个pH范围内生长。因此，绿藻可用于降低大气中的CO_2。细叶菊的体长20 ~ 50微米，宽度为长度的1/5。通过改变身体的形状，绿毛藻可以随着鞭毛移动。食物或营养物质是通过细胞表面直接吸收的。细叶菊在添加维生素B_1和B_<12>的轻无机培养基中均能生长。在黑暗中，需要有机能源。细叶草可作为测定生物材料和天然水中B_<12>存在的试验生物。当环境更适宜时，绿花草的数量会大幅增加。人们还知道，收获的绿藻细胞可用于生产蜡酯、角鲨烯和碳氢化合物等工业材料，或含有各种维生素、多不饱和脂肪酸和降压药的双功能食品。芥菜富含蛋白质。氨基酸得分和净蛋白质利用率分别为88分和79.9分，高于小球藻和螺旋藻等单细胞生物。草甘膦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，尤其是人体必需脂肪酸亚油酸，在绿豆自养生长时还含有相当多的花生四烯酸。生物合成的Paramylon具有海藻藻特有的β-1.3-葡聚糖，海藻糖也是人类可利用的营养物质。微量营养素，维生素通过暴露在强光照下或添加一些前体而变得极其丰富。这些观察结果表明，绿藻细胞是封闭生态系统中唯一的营养物。事实上，在月球基地一个封闭的环境生命维持系统中，人们长期以来一直在研究荠菜作为人类的营养物质。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
