中文拼音 [yábāoxíngchéng]
芽孢形成
英文
sporation-
The cultural conditions such as temperature, fermentation period and the compound of medium are studied. the result of test show that suitable factors for both bacterium to grow and active substance to produce are 28, 200rpm and 72 hours. the bacterium is gotten through centrifuge with 8000rpm for 20min. then the bacteria is diluted and colophony named s - 8 is put into and used to absorbed active substance for 4 hours
對該菌株發酵條件的研究表明：該菌株用馬鈴薯葡萄糖液體培養基發酵培養， 28 ， 200rpm搖瓶中振蕩培養72h可獲得高活性的發酵產物，用蘇雲金芽孢桿菌hd - 1做指示菌，將發酵液稀釋40倍生測仍可形成明顯的抑菌圈。Formerly, the bryophyta also included the liverworts and hornworts, which in the five kingdoms classification are now placed in separate phyla ( hepatophyta and anthocerophyta )
孢子萌發產生一個絲狀的單倍體，將來可以發育為芽體，進而形成整個植株。Protonema ( pl. protonemata ) the young bryophyte gametophyte that develops following spore germination. the mature gametophyte plants develop from buds that form at several points along the protonema
原絲體：苔蘚植物中直接由孢子萌發形成的結構稱為原絲體。原絲體上形成1個或幾個芽體，芽體進一步發育為配子體。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 ） 。The recombinant b. thuringiensis subsp. israelensis b - pmpx2 can produce a rhombus crystalline inclusion body during its sporulation sds - page analysis proved that cytlaa had overexpressed during the sporulation of the recombinant. it was found that b - pmpx2 strain remained stable toxicity, whatever during vegetative phase or sporulation phase, which was similar to the expression of mtxl gene in the strain of protease ( s ) - deficient b. sphaericus
同時，將來源於蘇雲金芽孢桿菌以色列亞種（ b . thuringiensissubsp . israelensis ， b . t . i ）的cytlaa基因和p20伴侶蛋白基因克隆連接到質粒pmt9中，並轉化到蘇雲金芽孢桿菌無晶體型中得到重組轉化子b - pmpx2 ，電鏡觀察發現重組轉化子b - pmpx2形成一菱形晶體。分享友人
