The best condition for extracting polysaccharide from porphyridium cruentum were as follow : alcohol concentration was 50 %, alcohol volume was 1 - fold time, percolation time was 0. 5h, the volume ratio of glycoprotein solution to sevag reagent was 2 : 1, time was 45min and sevag reagent was 4 : 1 between chloroform and butanol. the result also indicate that sodium acetate anhydrous and nh4cl were the best carbonic and nitrogen source for polysa
血色紫球藻的最優提取工藝為乙醇濃度50 % ，乙醇用量為1倍體積，醇沉時間為0 . 5小時;氯仿與正丁醇的比例4 : 1 ，樣液與sevag試劑的比例2 : 1 ，作用時間為45min ;五種碳源的影響差異不顯著，氮源的影響差異顯著，其中添加無水乙酸鈉和nh4ci的培養基多糖產率最高，分別為33 . 784mg / l和40 . 997mg / l 。 -
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
淡色紫球藻的最優提取工藝為乙醇濃度75 ，乙醇用量為2倍體積，醇沉時間為1小時；氯仿與正丁醇的比例3 ： 1 ，樣液與sevag試劑的比例1 ： 2 ，作用時間為45min ：由方差分析可得五種碳源和五種氮源對胞外多糖的影響不顯著，添加碳酸氫鈉和摘要nhoci的多糖產率最高，分別為41 -
Deproteinized from crude polysaccharide by adopting sevag method. through orthogonal test, we found that the best constitution for extracting polysaccharide from porphyridium aerugineum 755 were as follow : alcohol concentration was 50 %, alcohol volume was 3 - fold time, percolation time was 1. 5h, the volume ratio of glycoprotein solution to sevag reagent was 1 : 2, time was 15min and sevag reagent was 4 : 1 between chloroform and butanol. the result also indicate that lactose and ( nh4 ) 2so4 were the best carbonic and nitrogen sources for polysaccharide respectively
研究結果表明，三種紫球藻的最佳提取工藝各不相同，銅綠紫球藻的最優提取工藝為乙醇濃度50 ，乙醇用量為3倍體積，醇沉時間為1 . 5小時；氯仿與正丁醇的比例4 ： 1 ，樣液與sevag試劑的比例1 ： 2 ，作用時間為15min ；由方差分析可得五種碳源和五種氮源對胞外多糖的影響不顯著，其中添加乳糖和（ nh _ 4 ） _ 2so _ 4的培養基多糖產率最高，分別為37 . 296mg l和12 . 961mg l 。
