concentration of substrate meaning in English

底物浓度

Study of " ph memory " and activity water ( aw ) in processing of immobilization indicates that former factor has much effect on transformation and the latter just has little effect . permeabilization treating of baker ' s cell with alcohol and ultrasonic leads to lower transformation rate , which illustrates that permeabilization procedure has negative role on biotransformation with whole cell as biocatalyst in organic solvent . in simple dynamics research amount of biocatalysu concentration of substrate and reaction course are considered and all of them have remarkable effect on transformation
Ph记忆、水活度及通透性处理的实验结果表明， ph记忆对转化有明显的影响，水活度对模型反应的影响不大；作为完整细胞生物催化，细胞的通透性可能是传质阻力的重要组成部分，利用不同浓度的乙醇和超声波对细胞进行处理，结果表明，在有机相完整细胞生物催化中，通透性处理对转化产生的是负面影响。
