| 摘 要： | ＸＣＣＮＡＵ－９２生产黄原胶的工业发酵培养基成份是：蔗糖、玉米淀粉、氮源Ｘ、鱼粉、ＣａＣＯ３、ＭｇＳＯ４、Ｋ２ＨＰＯ４。适宜的Ｃ／Ｎ是：蔗糖（玉米淀粉）／氮源Ｘ＝６０．０／１．０，蔗糖（玉米淀粉）／鱼粉＝６０．０／１０．０。ＣａＣＯ３、ＭｇＳＯ４对ＸＣＣＮＡＵ－９２合成黄原胶有明显促进作用，Ｋ２ＨＰＯ４在发酵过程中使ｐＨ保持稳定，Ｍｎ２＋、Ｚｎ２＋、Ｆｅ３＋、柠檬酸和谷氨酸对生产黄原胶无促进作用。

| Abstract: | The ingredients of industrial fermentation medium for XCCNAU 92 producing xanthan gum were as follows:surcose,maize;nitrogen X,fishpowder;CaCO 3,MgSO 4,K 2HPO 4.The optimum C/N:surcose (maize starch)/nitrogen source X was 60.0/1.0;source (maize starch)/fish powder was 60.0/10.0.CaCO 3 or MgSO 4 evidently improved the synthesis of xanthan gum;K 2HPO 4 kept pH stability during fermentation;Mn 2+ ,Zn 2+ ,Fe 3+ ,citris acid and glutamic acid could not accelerate the xanthan gum synthesis. |
