中文摘要:
      对添加表面活性剂TritonX-1∞与补水两种不同工艺条件对黄原胶发酵的影响进行了研究.结果表明(1)产胶初期添加∞×10"TritonX-1∞的试验组对黄原胶产胶率的促进作用最为明显,其产胶率可达3.951∥1∞mL,较对照组提高约n%,碳源转化率为71.836%.(2)保持碳源含量6.5%,当发酵进行至36h时补加20%的水分,黄原胶的产胶率可达4.962∥100mL,较对照组提高约15%,碳源转化率为76.338%.
英文摘要:
      Effect of Triton X 100 or water added on xanthan gum fermentation was with Xanthomonas campestris HL 9901 studied. It showed that: (1) 40ppm Triton X 100 added at the beginning of gum producing to the fermentation media had significant effect on the productivity, and its gum productivity reached 3.951g/100mL, exceeded the control by 11%. The carbon transformation ratio was 71.836%. However, it improved the viscosity of colloid by the addition of Triton X 100 at the initiate of fermentation is superior to the control. (2) If the carbon concentration was kept at 6.5%, the gum productivity reached 4.962g/100mL, increased by 15% when 20% water added after 36h fermentation, and the carbon transformation ratio was 76.338%.
