限速步骤 meaning in English
rate-limiting step
Examples
- The organic fraction of municipal solid waste ( ofmsw ) is composed of various substance and its limiting step of anaerobic digestion resulting in reducing biogas production and process stabilization , this paper reviews the pretreatment of organic solid waste for improving ofmsw characteristics eliminating anaerobic limiting - step
摘要由于城市有机生活垃圾成分的复杂性和厌氧消化的限速步骤的影响，导致厌氧发酵的速度比较缓慢、产气量较少和工艺不稳定等问题。 - The supernatant fraction and the precipitation fractions were analyzed by western blotfor strain dh5 a / pkkfpga , 5 - 10 % pga precursors formed as inclusion bodies in the cytoplasm while no inclusion bodies formed in the periplasm , this suggested most pga precursors were transported to the periplasm and matured to active pga and indicated that the maturation of pga in strain dh5 / pkkfpga was limited by the translocation step
Western印迹分析表明对于菌株dh5 pkkfpga ， 5 - 10的原前体青霉g素酰化酶在胞内形成了包涵体，说明其成熟的限速步骤在胞内的运输阶段，而菌株dh5 psmlfpga则无明显包涵体形成，说明菌株dh5 psmlfpga改善了青霉素g酰化酶的合成流，因而其表达能力高于菌株dh5 pkkfpga 。 - In order to break down the rate - limited steps in the artemisinin biosynthesis to improve the artemisinin production and realize the industrial production of artemisinin , related key genes in artemisinin biosynthesis must be cloned and the regulatory patterns of key genes should be studied . for this purpose molecular cloning of related key genes in artemisinin biosynthesis was performed in this thesis work
利用现代分子生物学和基因工程技术手段，克隆青蒿素生成途径的关键酶基因，研究关键酶基因对青蒿素生物合成的调控规律，是打破青蒿素生物合成的限速步骤，大幅度提高青蒿素含量，最终达到利用植物生物技术工业化生产青蒿素的目的必须解决的关键问题。
