鏈變菌素 的英文怎麼說
中文拼音 [liànbiànjūnsù]
鏈變菌素
英文
dalacin-
A aada2 cassette, encoding aminoglycoside adenylyltransferase, was found in 2 isolates of shigella sonnei, and a two cassettes array of dfra1, encoding dihydrofolate reductase, and aadala in one isolate of shigella sonnei, and another two cassettes array of dfra1 7 and aada5 in two isolates of shigella sonnei and shigella flexneri y - variant each, and a dfrv cassette in one isolate of shigella flexneri 6, respectively
對其可變區測序分析，其中2株宋內志賀菌i類整合子均攜帶1個基因盒，為氨基糖昔腺營酞基轉移酶（ aminoglycosideadenylyltransferase ） az基因（ aa朔2 ） ，編碼對鏈黴素的抗性。S. lividans mutant strains zx1 ( dnd cluster deleted ) and zx64 ( dnda disrupted ) had pleiotropic mutations including low mel expression and poor sporulation. it was speculated that dnda together with its downstream dna ( 2. 5kb ) might be involved in these two phenotypes because dnda together with its downstream dna could restore normal sporulation and mel expression to zx64, while dndb and dndc had no such effect because lai and la2 showed no obvious difference in these two phenotypes from wild type s. lividans 1326
另外通過比較這幾個突變株及野生型菌株在產孢和黑色素基因（ mel ）表達方面的差異，推測dnda及其下游區域與變鉛青鏈黴菌的產孢和刺激外源黑色素基因的表達有關，而dndb和dndc則與之無關，因為la1和la2在這兩種表型上與野生型菌株無明顯差異。After the primary and secondary selection, 7 strains were tested to have higher productivity than the starting strain. of the 7 strains, strains s1 - 007, s1 - 123 and s1 - 018 were proved to produce more maduramicin than the starting strain. compared with 6236ug / ml of the starting strain, the productivity of the above three strains reached 8020 g / ml, 8254 g / mland9175 g / ml respectively
出發菌株尤馬馬杜拉放線菌s - 1 ，經過鏈黴素抗性篩選，挑取223個菌株，經過初篩和復篩得到7株菌株馬杜黴素的產量高於出發菌株，其中3個菌株s1 - 007 、 s1 - 123和s1 - 018的產素量與出發菌株的6236ug ml相比有較大提高，分別為8020ug ml ， 8254ug ml和9175ug / ml ，尤其是突變菌株s1 - 018的產量比出發菌株高47 。Also the ci represser was expressed, presumably from its own phage promoter and prevented transcription from pr at low temperature. moreover, s. lividans strains expressing the c. 100 kda pks were different in sporulation and antibiotic production compared to strains without the 2. 7 kb pks gene, suggesting that the pks protein was active in an unknown manner in streptomyces
表達pks的變鉛青鏈黴菌菌株在孢子形成和抗生素產生方面與沒有2 . 7kbpks基因的菌株相比較是有區別的，因而推測在鏈黴菌中表達的雙功能結構域pks蛋白具有活性。Streptomyces hygroscopicus subsp. yingchengensis 10 - 22 is an important agricultural strain which produces at least four antifungal antibiotics named as antibiotic 5102 - i, 5102 - ii, 5102 - iii, 5102 - iv respectively
吸水鏈黴菌應城變種10 - 22是一種有用的農用抗生素產生菌，它可以產生至少四類抗真菌抗生素，分別命名為5102 ?號、 5102 ?號、 5102 ?號、 5102 ?號抗生素。分享友人
