螺旋藻优质高产的新方法研究

Study of New Method for the High Yield and Superior Quality of Spirulina

螺旋藻是一种已有 35亿年生命史的最古老的原核光合生物 ,已被联合国粮农组织 (FAO)和世界卫生组织 (WHO)誉为“2 1世纪最佳保健食品”。通过多年多点室内外试验研究 ,探明了TA乳粉促进螺旋藻优质高产的应用技术。在螺旋藻工厂化生产中 ,向养殖池添加TA 0 0 1～ 0 0 2mg/L的TA乳粉 ,能促进螺旋藻的细胞分裂、增殖及藻丝生长 ,提高净光合速率和干物质积累 ,增强硝酸还原酶活力和呼吸强度 ,并显著提高蛋白质、氨基酸、藻蓝蛋白、β -胡萝卜素、叶绿素及类胡萝卜素等含量。在促进螺旋藻品质明显改善的同时 ,还能显著提高其生物产量 ,处理比对照的增产幅度可达 1 19～ 1 76 g/d·m2 ,增产率 2 0 %～ 30 %。用TA乳粉作为螺旋藻养殖的调节剂及其养殖工艺是一项新创举 ,并开拓了TA乳粉在微藻上应用研究的新领域 ,是促进螺旋藻优质高产的一种比较好的方法 ,应用前景十分广阔。

Spirulina is a kind of the most ancient pronucleus photosynthetic living things.Through many years of multiple points indoor and outdoor experiments and research, it has been proved the application technology of the TA emulsion powder for the promotion of superior quality and high yield of spirulina . In the factory mode of production of spirulina , 0.01～0.02 mg/L emulsion powder is added into the culture pool. It cannot onlg promote the cell fission of spirulina, the proliferation and growth of spirulina thread,the raise of pure rate of photosynthesis and accumulation of dry substance, but also strengthen the activity of nitric reductase and respiratory intensity of spirulina ,and remarkably increase the content of protein, amino acid, pheophytin β \|carotene, chlorophyll and carotenoid. At the same time, it significantly improve the quality and the biological yield of Spirulina . The amount of yield increase can be up to 1.19～1.76 g/d·m 2, the yield increase rate is 20%～30 %. To apply TA emulsion powder as the cultivation regulator and the cultivation technology is a new creation and the prospect of the application is cheerful.
