p.cruentum
porphyridium
Examples
- Porphyridium is one of the most important primal productivity in the sea , and large - scale cultivation is the most important problem in the exploitation of microalgae
对于紫球藻资源的开发利用，首先要解决该藻大规模培养问题。 - This paper reports that the optimum extraction of exopolysaccharides process by orthogonal design and the effect of different carbonic ( c ) and nitrogen ( n ) sources on cell growth rate and exopolysaccharides production of three porphyridiums
此外，研究不同碳源和氮源对三种紫球藻多糖产量的影响，确定适于多糖生产的最佳碳源和氮源。 - 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。 - 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
