interspecies fusion meaning in Chinese

种间融合

But in s . mycarofaciens , there is no distinctive propionate kinase , so that the utilization rate of propionic acid is lower than that of acetic acid . for this reason , it is hoped that the higher producers would be obtained by protoplast interspecies fusion between s . mycarofaciens and s . erythreus , which would transfer propionate kinase of s . erythreus to s . mycarofaciens . therefore , the fusion cells could use propionic acid as precursor in synthesis of mdma _ ( 1 ) , which would reduce the production costs
根据文献报道，红霉素链霉菌中的丙酸激酶对丙酸的利用率是对乙酸的利用率的13倍；而在生米卡链霉菌中，无特异的丙酸激酶，菌体对丙酸的利用低于对乙酸的利用，因此希望利用原生质体种间融合的方法将红霉素链霉菌的丙酸激酶基因转移到生米卡链霉菌中，从而使融合子能够利用丙酸盐作为合成mdma _ 1的前体，提高mdma _ 1的产量，降低生产成本。
