He-Ne激光诱变钝顶螺旋藻的初步研究

Studies on Mutagenicing of Spirulina Platensis Induced by He-Ne Laser

本文研究了钝顶螺旋藻在不同剂量的Ｈｅ－Ｎｅ（６３２．８ｎｍ）激光照射下引起的生理生化特性变化。研究结果表明，与出发菌株相比，经激光照射后，藻体在形态、干重、含氮量和胞外多糖等方面都有不同程度的变化，其中胞外多糖含量，提高了１９３％，展示了激光诱变螺旋藻的良好前景。

:The Spirualina Platensis initial strain was induced with HeNe Laser at different doses.research on the changes of the physiological and biochemical characteristics induced after treating with HeNe Laser indicated that in comparison with initial strains,their dry weight,nitrogen content,exocellular polysaccharides and morpha were varied at different degrees.Among these,the exocellular polysaccharides were increased by 193%. This means that Laser mutagenicing spirulina platensis has a bright perspective.
