長孢菌素 的英文怎麼說
中文拼音 [zhǎngbāojūnsù]
長孢菌素
英文
longinosporin-
Israelensis recombinants, which contained recombinants plasmid pmt4 and pmt9 respectively, were obtained by electroporation. the bioassay results showed that the recombinants b - pmt9 and b - pmt4 had toxicities both to resistant and susceptible c. quinqnefasciatus larvae during vegetative growth stage, having the lc ? o values similar to that of. fi. sssii - 1. however, the toxic levels of the final sporulated cultures of recombinants b - pmt4 and b - pmt9 differed, with a lcso value of 2 49mg / ml for b - pmt9 and little toxicity for b - pmt4 by using the plasmid pmt9, m txl gene from b. sphaericus was ligated with p20 and cytjaa gene, giving recombinant plasmid pmpx2
含有pmt9和pmt4的大腸桿菌轉化子能表達產生mtx1毒素，發酵液對敏感和抗性致倦庫蚊幼蟲具有中度毒殺作用；含有pmt9和pmt4的蘇雲金芽孢桿菌轉化子b - pmt9和b - pmt4在營養體生長階段對敏感蚊幼和抗性幼蟲也具有毒性，毒力與野生型b . sss - 1相當，而不同轉化子在芽孢形成期的毒力因插入的mtx1基因轉錄方向不同而表現出差異，其中b - pmt4對目標蚊幼毒力極低（ lc _ （ 50 ） 10mg ml ） ，而b - pmt9對蚊幼蟲具有毒性（ lc _ （ 50 ） = 2 . 49mg ml ） 。2. the resistence of transformators were selected by g418 after co - culture with agrobactrium tumeflien, which was 40 mg / l in subcultured medium and 50mg / l in differeniated medium. in the process of killing agrobactrium, cef, amp or carb were also useful and the time of inhibition was long too
經與農桿菌共培養后轉化子的鑒定選用g418 ，在繼代篩選培養基中添加40mg l ，在分化篩選培養基中添加50mg l ；在除菌過程中，頭孢噻肟鈉、羧芐青霉素、氨芐青霉素抑菌效果較好，抑菌時間較長。Sonication - assisted agrobacterium - mediated transformation ( saat ) can increase the efficiency of transformation. 2s sonication can enhance the gus gene transient expression and induction of resistant buds without leaves incision
頭孢毒素（ cef ）對不定芽的誘導有一定的抑制作用，哌拉西林鈉（ pip ）對不定芽的誘導抑制作用稍弱，以pip400mg / l作為抑菌生長濃度。Anti - epileptic peptide makes the latency period of the epilepsy caused by cephalosporin shorter than the contrast group, the extent lighter, and the continual period shorter
抗癲癇肽使頭孢菌素引起癲癇的潛伏期比對照組長，發作程度減輕，平均總持續時間縮短。Cefotaxime inhibited the bud regeneration at concentrations more than 250 mg / l, so the concentration used in suppression of agrobacterium is 200 mg / l
頭孢黴素（ ce ）對大巖桐不定芽的誘導也有抑制作用，但較卡那黴素弱，其抑制農桿菌生長的適宜濃度為200mg l 。分享友人
