• In this thesis , the fist cyanophage isolated in china was investigated with regard to the molecular biological characters . techniques for the large harvest and the electronic microscopy negative staining of the cyanophage were established . the genome library was constructed
  论文对我国淡水中分离得到的一株蓝藻病毒(噬藻体)的某些分子生物学特性进行了研究，建立了其大量增殖与电镜染色的技术，构建了基因组文库，并对部分序列进行了测定与和分析比较。
• A new concentration system , the backflushing ultrafiltration system , was constructed with the isolated cyanophage pp in our lab associated with the ultrafiltration technique . basing on this system , the cyanophage concentration multiple could reach up to 30 times and the recovery rate of the cyanophage could exceed 90 %
  浓缩是研究噬藻体的重要前期工作，我们以本实验室分离的淡水噬藻体pp为实验材料，结合超滤技术，建立了一套能够有效浓缩水样中噬藻体的方法- - -反冲超滤法。此浓缩技术可使噬藻体的回收率达90以上，浓缩倍数达30倍。
• Under mixed culturing conditions , it was observed that bacterial number rapidly incre ; ised soon after the lysing of host cells . on the contrary , while the non - host cyanobacterium ( i . e . anabaena flos - aquae ) was incubated in the mix culturing system , the breeding of the bacteria could be inhibited . it may be suggested from the result above that cyanophage could bring about the changes in microorganism populations
  调查结果显示， 19个采集的水样中有6个含有裂解织线藻的噬藻体，而且水样未经浓缩即能裂解宿主，说明噬藻体在淡水中分布较广泛，裂解性也较强；混合培养条件下的研究结果表明，噬藻体裂解宿主后，细菌数量快速增加，而当培养系统中有非宿主藻类存在时，细菌的增殖则受到非宿主藻的抑制，说明噬藻体可以显著改变系统中微生物的种群结构。
• Again , using cyanophage pp and adopting orthogonal design , we have performed the studies on the effects of several environmental factors on the multiplication of the cyanophage . results are as follows : in the experiment of measuring the adsorption rate , temperature was found to be the primary influencing factor and displayed an obvious significance by the statistics analysis
  以噬藻体pp为对象运用正交设计的实验方法，我们还研究了几种环境因子对噬藻体增殖的影响，结果如下：在测定吸附率的实验中，我们发现温度是主要的影响因素，并且在统计学上有显著意义。
• As temperature rose , the saturated adsorption rate tended to increase , and the time to reach saturation would become longer . comparatively , the sunlight radiation showed a minor influence . with the intensity of sunlight radiation strengthened , the adsorption speed of the cyanophage to the host gradually quickened , and reached the maximum of 62 . 4 % at 28cand 2000 lux
