突变菌株 meaning in English
mutant strain
Examples
- . the conditions of the liquid state and solid state fermentation that m12 - 69 produced monaclin k were studied
第五，对红曲霉突变菌株m12一69产monacofink的液态和固态发酵条件进行了初步优化研究。 - An auto - controlled fermentor was used to culture these strains under nitrogen fixation conditions and the nitrogneases were effectively depressed
在固氮条件下，所构建固氮酶突变菌株均表现为严格的nif ~ -表型，不能进行固氮生长。 - Antimicrobial agents susceptibility of this strain illustrated that it was resistant to gentamicin , streptomycin , ciprofloxacin , ceftazidime and imipinem
应用此条件经过不断筛选，最后获得对多种抗生素耐药的突变菌株pa9911 - c64 。 - Lividans mutant strains la1 and la2 generated by gene replacement in dndb and dndc were obtained respectively . both of these two mutants lost dnd phenotype because of disruption of a respective dnd gene
首先利用基因置换实验获得分别在dndb 、 dndc基因内部发生基因中断的突变菌株la1利la2 ，并通过southern杂交进行了验证。 - After ten generations growing on drug - free plate , the resistance of pa9911 - c64 kept unchanged . 800 broth samples of endophytes were tested on this model , among which several samples showed antimicrobial or synergic activity
以此耐药突变菌株作为模型，对800份植物内生菌所产生的发酵样品进行了初步筛选，并获得了几份活性样品。
