| 9. | The overseas studies on it have been reported since 1960 , but few researches have been carried out in china . in this paper , the culture condition , polysaccharide extraction and rapd analysis of three species of porphyridium were studied 本文主要研究三种紫球藻培养条件的优化,胞外多糖的提取工艺和不同碳源、氮源对多糖产量的影响以及三种紫球藻rapd分析。 |
| 10. | The polysaccharide production were 37 . 296mg / l and 12 . 961mg / l . the best conditions for extracting polysaccharide from porphyridium purpureum were as follow : alcohol concentration was 75 % , alcohol volume was 2 - fold time , percolation time was 1h , the volume ratio of glycoprotein solution to sevag reagent was 1 : 2 , time was 45min and sevag reagent was 3 : 1 between chloroform and butanol . the result also indicate that nahco3 and nh4cl were the best carbonic and nitrogen sources for polysaccharide respectively 淡色紫球藻的最优提取工艺为乙醇浓度75 ,乙醇用量为2倍体积,醇沉时间为1小时;氯仿与正丁醇的比例3 : 1 ,样液与sevag试剂的比例1 : 2 ,作用时间为45min :由方差分析可得五种碳源和五种氮源对胞外多糖的影响不显著,添加碳酸氢钠和摘要nhoci的多糖产率最高,分别为41 |
