噬藻體 的英文怎麼說
中文拼音 [shìzǎotǐ]
噬藻體
英文
phycophage-
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
調查結果顯示， 19個採集的水樣中有6個含有裂解織線藻的噬藻體，而且水樣未經濃縮即能裂解宿主，說明噬藻體在淡水中分佈較廣泛，裂解性也較強；混合培養條件下的研究結果表明，噬藻體裂解宿主后，細菌數量快速增加，而當培養系統中有非宿主藻類存在時，細菌的增殖則受到非宿主藻的抑制，說明噬藻體可以顯著改變系統中微生物的種群結構。Under the dark condition or at low temperatures, the cyanophage would n ' t multiply, but the elevation in both temperature and sunlight would bring about the burst size to increase
測定釋放量和潛伏期的實驗結果表明，溫度和光照是主要的影響因子，在無光照或溫度較低的情況下，噬藻體幾乎不增殖。The burst size of the cyanophage was ca. 200 pfu ? cell " 1. the rate of adsorption to host was markedly higher under light condition than that under dark condition ( p = 0. 02 ), and light was necessary for infection
此外，固體培養條件下，織線藻的生長速率與噬藻斑的擴大之間有明顯的同步性，即生長速度越大，噬藻斑的擴大就越明顯。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 %
濃縮是研究噬藻體的重要前期工作，我們以本實驗室分離的淡水噬藻體pp為實驗材料，結合超濾技術，建立了一套能夠有效濃縮水樣中噬藻體的方法- - -反沖超濾法。此濃縮技術可使噬藻體的回收率達90以上，濃縮倍數達30倍。Under trasmission electronic microscope ( tem ), the cyanophage showed a bacteria - phage shape with head diameter at 52nm and short tail ( almost invisible )
電鏡照片顯示該噬藻體為噬菌體形態，頭部直徑為52nm ，尾部很短，幾乎不可見。Several methods for measuring the lysing cycle and burst size of the cyanophage were tested. it was established that cell counting method was more convenient and exact for confirming the lysing cycle. burst size obtained by 1 pfu infecting was reliable
我們研究了確定該噬藻體裂解周期和釋放量的多種方法，認為細胞計數法是測量裂解周期既方便又準確的方法，而採用1pfu的感染可獲得噬藻體的準確釋放量。More studies were conducted on both the physiology and ecology of the cyanophage
在上述研究的基礎上，我們還系統開展了噬藻體生理與生態特性的研究。Investigation in details on a freshwater cyanophage isolated in china infecting plectonema and phormidium is presented in this thesis
我們在國內首次分離和報道了淡水噬藻體（藍藻病毒） ，其宿主為織線藻和席藻。This method was also effective for concentrating virus form large volume water samples. moreover / the concertration multiple of cyanophage pp could rise to nearly one - hundred times when two - step backflushing ultrafiltration technique was adopted
此法也適用於大量水樣的處理，而且當採用兩步反沖超濾技術時，噬藻體的濃縮倍數可以提升到近100倍。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
論文對我國淡水中分離得到的一株藍藻病毒（噬藻體）的某些分子生物學特性進行了研究，建立了其大量增殖與電鏡染色的技術，構建了基因組文庫，並對部分序列進行了測定與和分析比較。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
以噬藻體pp為對象運用正交設計的實驗方法，我們還研究了幾種環境因子對噬藻體增殖的影響，結果如下：在測定吸附率的實驗中，我們發現溫度是主要的影響因素，並且在統計學上有顯著意義。Preliminary studies on the ecological characters of freshwater cyanophage were carried out under both field condition and culturing system. the field investigation result showed that 6 in 19 water samples contained cyanophages lysing plectonema and the lysis phenomenon were readily observed without concentrating the water
對淡水噬藻體的生態學進行了初步研究，包括淡水中噬藻體分佈及感染力的調查與人工混合培養條件下噬藻體裂解宿主引起微生物和藻類種群變化的研究。分享友人
