螺旋藻是一种高蛋白生物资源。研究结果表明,在我国开发利用螺旋藻这项生物技术具有很大的可行性。但是,培养液中碳源的供给是直接影响藻体光合效率的主要因素之一。据国外研究结果,培养液中NaHCO_3的浓度对螺旋藻干物质的累积速率呈如下顺序:18.0>9.0>4.5(克/升)。在螺旋藻的培养液中,NaHCQ_3的浓度以4.5克/升的经济效益为最高。 现将培养液中NaHCO_3浓度对钝顶螺旋藻净光合速率的试验结果简报如下。 材料与方法 取中科院武汉水生所提供的钝顶螺旋藻(Spirulina Platensis)少许,散于含2％
Spirulina is a high protein biological resources. The results show that the development and utilization of Spirulina in our biotechnology has great feasibility. However, the supply of carbon source in culture solution is one of the main factors that directly affect the photosynthetic efficiency of algae. According to the results of foreign studies, the accumulation rate of NaHCO 3 in culture medium on the spirulina dry matter in the following order: 18.0> 9.0> 4.5 (g / L). Spirulina culture medium, NaHCQ_3 concentration of 4.5 g / l of the highest economic benefits. Now the culture medium NaHCO_3 concentration of Spirulina net photosynthetic rate test results are summarized below. Materials and Methods Take Spirulina Platensis from Wuhan Aquatic Institute of Chinese Academy of Sciences,
