In order to cutting down the cost, flocculation of recombined Erwinia carotovora-Eccl3B cell from broth, influence of temperature, pH and oxidants on the separation of PHB were studied; and the method which measure the molecular weight of PHB by intrinsic viscosity was also studied; furthermore, a phenomenon was found that insolubility of PHB in chloroform can be changed by pretreated at over 120℃ for the fist time, and the mechanism of this phenomenon was explored.

为了降低成本，提高生产效率，本文针对发酵法生产PHB过程中存在的，发酵液难以分离沉淀，非有机溶剂提取PHB时分子量严重降低等问题，进行了发酵液的絮凝，及温度、pH、氧化剂对提取PHB影响的研究。并对粘度法测定PHB分子量的方法进行了研究，同时，对于研究过程中发现的，加热后PHB在三氯甲烷中的溶解性变化及其原因进行了探索。

This is, further to certify that the parent plants were grown on the farm in which the intensive controls against the vectors of Erwinia stewartii were carried out, and these plants were inspected on the field during the most active growing season and found to be free from the pest mentioned above.

（兹证明母本植物种植地已针对玉米细菌性枯萎病菌媒介采取严密的防控措施，并在这些植物最具活力的生长季节进行田间检查，未发现玉米细菌性枯萎病菌。

Result The results revealed that different concentration of C6-HSL could obviously inhibit the growth rate of root and the number of roots, but have no effects on plant height, number of nodes and leaf size. The POD and SOD activities and the concentration of H2O2 showed a significantly increased when the potato implants were pretreated with C6-HSL, however, no effect of C6-HSL pretreatment on PAL and PPO activities were found. The ability of resistance aginst Erwinia carotovora subp. carotovora was signifinantly improved after treated by C6-HSL. Incidence was obviously lower than the control group.

结果］不同浓度的C6-HSL能明显抑制马铃薯的出根率和生根数，而对株高、茎节数及叶片大小没有影响；植物标志性防御酶类中POD和SOD的活性以及H2O2的产生量经C6-HSL诱导后显著提高，而PAL和PPO的活性则没有明显变化；抗病试验中，经C6-HSL诱导的马铃薯植株能有效抑制胡萝卜软腐欧文氏菌的侵染，发病率明显低于对照组。
