High performance ion exchange chromatography was applied in studying qualitatively and quantitatively of bacteria, which was shown as follows : firstly, physio - biochemical characteristics of bacteria was investigated by ion exchange chromatography. for the first time spores and nutrient of bacillus pumilus had been separated successfully by chromatography. chromatographial behaviors of bacteria at different cultivating environment and different growth phase were also studied
本文利用高效液相離子交換色譜系統研究細菌學，探討了該方法在細菌定性、定量方面的應用，主要包括三個方面：首先，利用離子交換色譜系統表徵細菌生理、生態方面的變化，首次成功地在色譜上區分了短小芽孢桿菌的芽孢及營養體；考察了不同的培養環境對細菌色譜行為的影響及不同生長階段的細菌的色譜行為。Factors of inducing dormancy, determining the stage of flower initiation and dormancy development, the methods of avoiding dormancy and stimulating adequate and uniform budburst, the growth and development of tree and the cultural management, the cause of secondary dormancy and the methods of avoidance of secondary dormancy, and the breeding of non - dormant cultivars are the critical points for non - dormancy culture
溫帶地區無休眠栽培的研究重點是：自然休眠誘導因子的確定；花芽分化進程及自然休眠進程的精確界定；避免進入深度休眠及促芽整齊萌發的配套技術；無休眠栽培條件下樹體的生長發育規律及樹體綜合管理技術；二次休眠現象發生的原因和克服措施；無休眠品種的選育。Restriction of vegetative growth to ensure flower initiation, defoliation to prevent the onset of dormancy, stimulation of adequate and uniform budburst, and avoidance of secondary dormancy are essential for success of non - dormancy culture
控制營養生長、保證花芽分化，使樹體避開休眠，促進足夠多的芽整齊萌發，避免二次休眠的發生是無休眠栽培成功的4項重要保證。Icp analysis shows that the nutritious elements in the organs of bean sprouts, such as roots and hycopotys change after yuanji treatment, exposing that the effect of yuanji treatment is the omnidirectional and multi - level holographic operation, and the orderly change of different organs from seeds to bean sprouts
三元能量的不同載體對豆芽處理的效應，通過icp分析表明，豆芽的不同器官（如根與胚軸）的營養元素多有變化，說明三元能量的效應是全方位多層次的全息運化，是從種子向豆芽的各器官有序變化，從而步步促進生長發育。The optimized parameters of high - frequency in bacillus thuringiensis plasmid - free mutant bmb171 by electroporation was studied. it showed that a highest electro - transformation frequency could be obtained, when sg solution was used as the buffer, and a 10. 0 kv / cm of field strength, one time of pulse as well as a growth phase of recipient cells at the exponential phase ( od650nm value was 0. 2 - 0. 3 ) were selected
對用電脈沖法轉化蘇雲金芽胞桿菌受體菌bmb171優化條件的研究結果表明，採用sg溶液作電脈沖緩沖液，用10 . 0kv cm的脈沖場強和1次電脈沖（ 4 . 6ms ） ，以及採用對數前期（ od _ （ 650 ）約0 . 2 0 . 3 ）收獲的受體菌，可以達到最高轉化頻率。The display of penicillin g acylase from bacillus megaterium not only offers the possibility of applying this technology for the selection of penicillin acylases with new side - chain specificities, but also facilitates our screen of mutant library constructed by using dna shuffling technique
這是首次在噬菌體表面展示出有活力的巨大芽孢桿菌青霉素g酰化酶，為利用噬菌體展示技術進行青霉素g酰化酶突變庫的篩選奠定了基礎。分享友人
