| 摘 要： | 比较不同ＮａＣｌ、Ｃａ２＋、ＰＯ３－４等离子浓度对嗜盐隐杆藻（Ａｐｈａｎｏｔｈｅｃｅｈａｌｏｐｈｙｔｉｃａ）细胞生长及胞外多糖（Ｅｘｏｐｏｌｙｓａｃ－ｃｈａｒｉｄｅＥＰＳ）产量的影响。在各影响因子不同浓度的培养条件下，０．５ｍｏｌ／Ｌ的ＮａＣｌ、１．０ｇ／Ｌ的Ｃａ（ＮＯ３）２·４Ｈ２Ｏ、０．１ｇ／Ｌ的ＫＨ２ＰＯ４分别是其最佳生长浓度。ＥＰＳ的产量在０．５ｍｏｌ／ＬＮａＣｌ、，０．５ｇ／ＬＣａ（ＮＯ３）２·４Ｈ２Ｏ、０．５ｇ／Ｌ的ＫＨ２ＰＯ４培养条件下最高。在较低的Ｃａ２＋、Ｍｇ２＋、ＰＯ３－４浓度下可提高ＥＰＳ产率。

| Abstract: | The cell growth and EPS production are investigated under different growth conditions by changing some nutritional and physicalchemical parameters known to affect the synthesis of expolysaccharides and cell number. {Among} the factors tested, 0.5 mol/L NaCl, 1.0 g/L Ca(NO-3)-24H-2O, 0.10 g/L KH-2PO-4 are suitable for cell growth concentration and alga can produce more EPS in culture of 0.5 mol/L NaCl, 0.5 g/L Ca(NO-3)-24H-2O, {0.05} g/L KH-2PO-4. Limitation of Ca {2 }, PO {3-}--4 all can induce a significant enhancement of EPS synthesis. |
